编程语言pat

‘壹’ 电脑编程有那几种语言

机器语言，没用过，不过是计算机最底层的语言，直接运行的，debug就是用这种语言
汇编语言，比机器语言高级，但仍然很繁琐
高级语言，就是通常意义上的编程语言，有很多种，列举一些（括号里是对应的编译器）
BASIC(VB),纯C（TurboC），C++（Visual C++，C++Builder），C#（Visual C#），Pascal（Turbo Pascal，Delphi），Java（Sun Java），J#（Visual J#）高级语言有很多，常用的就是这些，

‘贰’ pat每年什么时间考试

国家统考时间：3月、6月、9月、12月。考试一般都是在月底，现在应该还可以报名。

对外汉语教师资格证书是从事对外汉语教学能力的一个认定，也是对外汉语教学能力的一个证明。我国颁发的对外汉语教师资格证书是IPA国际注册对外汉语教师资格证；
“IPA国际注册汉语教师资格证”是国际认证协会根据国际上对汉语教师的极大需求的状况而推出的资格认证，由国家人事部授权在全国推行，并实行全国统考。国际认证协会推出的“国际注册汉语教师资格证书”是被国际100多国家认可的，具有权威性。国际职业资格证书获得了美国联邦政府的全面认可，并得到美国国务卿的签字。在中国，国际认证协会获得了国家人事部（人力资源和社会保障部）权威认可并授权儒森汉语（颁发CETTIC认证）在全国推行。
国际注册对外汉语教师资格证证书是中国地区唯一获得中国驻美国大使馆的全面认证，并由中国使领馆代表签字的。凭借国际注册对外汉语教师资格证证书，可申请获得中国驻美大使馆对证书及学历鉴定和中国人事部国家人才网的鉴定，“国际注册汉语教师资格证”，实行统一考试。通过考试者将由中国驻美大使馆、美国国务院、国家人事部全国人才流动中心、国际认证协会、中国国家人才网对其联合认证。颁发相应资格证书。
备注：IPA国际认证协会介绍
国际认证协会International Profession Certification Association（简称IPA）是资质齐全的驻京国际认证机构。是中国区唯一经美国国务院签印并由中国驻美国大使馆认证认可的国际认证协会。
国际认证协会得到了世界各国政府机构和市场的广泛认可和欢迎。在中国，国际认证协会获得国家质量监督检验检疫总局的权威认证认可，经北京公安局出入境管理处登记备案的合法国际认证机构。败族 国际认证协会与欧洲商业管理学院、哈佛大学、剑桥大学、耶鲁大学、斯坦福大学等近百家世界知名高等院校和认证机构建立了面向世界范围的专业等级察缺弊认证考试，并已为IBM、GE、DELL、国际金融管理集团等数百家跨国公司企业中的高级管理人员提供了专业的培训认证服务。

PAT对外汉语教师资格证是中华人民共和国人力资源和社会劳动保障部中职协颁发的我国唯一对外汉语教师从业资格证书，背面左上方烫有凹型为“中国职协”标志，下方烫有型“中华人民共和国人力资源和社会保障部中国职工教育和职业培训协会监制”字样。由国家官方认证并可到人社部中职协官方网站查询证书编号。
中文名：PAT对外汉语教师资格证
证书划分：初级、中级、高级三个级别
考试等级：同一试题根据考试分数高低确等级

人社部中职协PAT报考中心设立在上海，并且唯一授权扮纳于汉之音国际汉语学院。
中华人民共和国人力资源和社会保障部是统筹机关企事业单位人员管理和统筹城乡就业和社会保障政策的中国国家权力机构。十一届全国人大一次会议第四次全体会议（2008.03.11）“国务院机构改革方案”审议通过组建，同时组建国家公务员局，由人力资源和社会保障部管理。不再保留人事部、劳动和社会保障部。2008年3月31日正式挂牌，而其官方网站也于同日开始运行。

编程语言历史

《BYTE》：A Brief History of Programming Languages
We’ve come a long way from computers programmed with wires and punch cards. Maybe not as far as some would like, though. Here are the innovations in programming.

ca. 1946

Konrad Zuse , a German engineer working alone while hiding out in the Bavarian Alps, develops Plankalkul. He applies the language to, among other things, chess.

--------------------------------------------------------------------------------

1949

Short Code , the first computer language actually used on an electronic computing device, appears. It is, however, a "hand-compiled" language.

--------------------------------------------------------------------------------

1951

Grace Hopper , working for Remington Rand, begins design work on the first widely known compiler, named A-0. When the language is released by Rand in 1957, it is called MATH-MATIC.

--------------------------------------------------------------------------------

1952

Alick E. Glennie , in his spare time at the University of Manchester, devises a programming system called AUTOCODE, a rudimentary compiler.

--------------------------------------------------------------------------------

1957

FORTRAN --mathematical FORmula TRANslating system--appears. Heading the team is John Backus, who goes on to contribute to the development of ALGOL and the well-known syntax-specification system known as BNF.

--------------------------------------------------------------------------------

1958

FORTRAN II appears, able to handle subroutines and links to assembly language. John McCarthy at M.I.T. begins work on LISP--LISt Processing.

The original specification for ALGOL appears. The specific ation does not describe how data will be input or output; that is left to the indivial implementations.

--------------------------------------------------------------------------------

1959

LISP 1.5 appears. COBOL is created by the Conference on Data Systems and Languages (CODASYL).

--------------------------------------------------------------------------------

1960

ALGOL 60 , the first block-structured language, appears. This is the root of the family tree that will ultimately proce the likes of Pascal. ALGOL goes on to become the most popular language in Europe in the mid- to late-1960s.

Sometime in the early 1960s , Kenneth Iverson begins work on the language that will become APL--A Programming Language. It uses a specialized character set that, for proper use, requires APL-compatible I/O devices.

--------------------------------------------------------------------------------

1962

APL is documented in Iverson’s book, A Pro gramming Language .

FORTRAN IV appears.

Work begins on the sure-fire winner of the "clever acronym" award, SNOBOL--StriNg-Oriented symBOlic Language. It will spawn other clever acronyms: FASBOL, a SNOBOL compiler (in 1971), and SPITBOL--SPeedy ImplemenTation of snoBOL--also in 1971.

--------------------------------------------------------------------------------

1963

ALGOL 60 is revised.

Work begins on PL/1.

--------------------------------------------------------------------------------

1964

APL\360 is implemented.

At Dartmouth University , professors John G. Kemeny and Thomas E. Kurtz invent BASIC. The first implementation is a compiler. The first BASIC program runs at about 4:00 a.m. on May 1, 1964.

PL/1 is released.

-----------------------------------------------------------------------------

1965

SNOBOL3 appears.

--------------------------------------------------------------------------------

1966

FORTRAN 66 appears.

LISP 2 appears.

Work begins on LOGO at Bolt, Beranek, & Newman. The team is headed by Wally Fuerzeig and includes Seymour Papert. LOGO is best known for its "turtle graphics."

--------------------------------------------------------------------------------

1967

SNOBOL4 , a much-enhanced SNOBOL, appears.

--------------------------------------------------------------------------------

1968

ALGOL 68 , a monster compared to ALGOL 60, appears. Some members of the specifications committee--including C.A.R. Hoare and Niklaus Wirth--protest its approval. ALGOL 68 proves difficult to implement.

ALTRAN , a FORTRAN variant, appears.

COBOL is officially defined by ANSI.

Niklaus Wirth begins work on Pascal.

--------------------------------------------------------------------------------

1969

500 people attend an APL conference at IBM’s headquarters in Armonk, New York. The demands for APL’s distribution are so great that the event is later referred to as "The March on Armonk."

--------------------------------------------------------------------------------

1970

Sometime in the early 1970s , Charles Moore writes the first significant programs in his new language, Forth.

Work on Prolog begins about this time.

Also sometime in the early 1970s , work on Smalltalk begins at Xerox PARC, led by Alan Kay. Early versions will include Smalltalk-72, Smalltalk-74, and Smalltalk-76.

An implementation of Pascal appears on a CDC 6000-series computer.

Icon , a descendant of SNOBOL4, appears.

--------------------------------------------------------------------------------

1972

The manuscript for Konrad Zuse’s Plankalkul (see 1946) is finally published.

Denni s Ritchie proces C. The definitive reference manual for it will not appear until 1974.

The first implementation of Prolog -- by Alain Colmerauer and Phillip Roussel -- appears.

--------------------------------------------------------------------------------

1974

Another ANSI specification for COBOL appears.

--------------------------------------------------------------------------------

1975

‘肆’ c语言中的error: expected expression该怎么解决

函数调用错。

int x;

scanf("%d",&x);

int y=square(x);

printf("%d",y);

return 0;

或：

该行改为

input(pat);

把pat的定义移到前面去

int select;

struct patient pat;

fflush(stdin);

(4)编程语言pat扩展阅读：

C语言包含的各种控制祥没逗语句仅有9种，关键字也只有32 个，程序的编写要求不严格且以小写字母为主，对许多不必要的部分进行了精简。实际上，语句构成与硬件有关联的较少，且C语言本身不提供与硬件相关的输入输出、文件管理等功能，如需此类功能，需要通过配合编译系统所支持的谨卖各类库进行编程，故c语言拥有非常简洁的编译系统。察禅

‘伍’ pat算竞赛吗

算的。
PAT，是一项全国范围内非常有影响力的计算机程序能力考试。
PAT的考试，是不限编程语言的。PAT有非常细致人性化的“难度等级”设置—基础级、乙级、甲级到顶级。而其中的基础级又可划分为青铜、白银、黄金、白金、钻石5个段位。
PAT旨在通过统一组织的在线考试及自动评测方法客观地评判考生的算法设计与程序设计实现能力，科学地评价计算机程序设计人才，为企业选拔人让裂才提供参考标准。
目坦蚂闭前PAT已成为IT界的标准化能力测试，得到包括Google中国、Microsoft、雅虎、网易、网络、腾讯等在内的百余家大中小型各级企业的认可和支持。同时，从19考研起，浙江大学计算机学院硕士研究生招生考试上机复试成绩可以用前物猜一年的甲级或顶级PAT成绩替代。考试，汉语词语，拼音是kǎoshì，意思是通过书面或口头回答、现场操作等方式考查人的技能或知识水平。细致的等级划分，使得每一个孩子都可以从中找到自己的适用等级。（学习Python、C++的小创客均可参加）。

‘陆’ 单片机C语言编程：让8个LED流水灯以0.2s时间间隔从左到右依次点亮然后重复实现

#include<reg52.h>
#include<intrins.h>
void delay(unsigned int z );
void main()
{
unsigned int a;
unsigned char b=0xfe;
for(a=0;a<8;a++)
{
P1=b;//P1口接8个LED灯
delay(200);
b=_crol_ (b,1);
}
}
void delay(unsigned int z)
{
unsigned int i;
for(;z>0;z--) //延迟时间自己算吧
for(i=110;i>0;i--);
}
用汇编写这个容易点
main: mov a,#0feh
mov r0,#8
loop: mov p1,a
acall delay
rl a
djnz r0,loop
delay：mov r6,#0ffh
loop1: mov r7,#01h
djnz r7,$
djnz r6,loop1
ret
end
好像是这样,延迟时间可能不太准，也是P1口接8个LED灯
