使用getchar()函数暂停控制台窗口

使用GNU编译器 -

gcc myapp.c -o myapp.exe
./myapp.exe
Hello World

示例代码：

#include <stdio.h>

int main(void) {
  printf(Hello World);
  getchar();
}

#include <stdio.h> int main (void) { printf ("tutorial from book 2s.c om.\\n"); printf ("from book2s.com.\\n");

#include <stdio.h> int main (void) { printf ("Testing...\\n..1\\n...2\\n....3\\n"); return 0;//fromwww.y iiba i .co m

#include <stdio.h> int main (void) { int sum;//fromw w w. yiib ai . com sum = 50 + 25; printf ("The sum of 50 and 25 is %i\\n", sum);

#include <stdio.h> int main (void) { int value1, value2, sum; value1 = 50;/*ww w.yIi ba i. com*/ value2 = 25;

#include <stdio.h> int main()/* from w ww.yi ba I.c om*/ { int planets = 8; int friends = 6; int potterBooks = 7;

要求用户输入浮点，整数并将其打印在屏幕上，以下是代码的实现: #include <stdio.h>

C语言在屏幕上打印一条消息，参考以下实现代码: #include <stdio.h> int main() { printf("this is a test");

#include <stdio.h> int main(void) { int total; int cats; int dogs; int ponies; int others; cats = 4; dogs = 3;

#include <stdio.h> int main(void) { int ch; int ct = 0; while ((ch = getchar()) != EOF) ct++; printf("%d characters read\\n", ct);

switch 不使用 break 语句： #include <stdio.h> int main() { int iResponse = 0; printf("\\n1\\tSports\\n");

#include <stdio.h> int main() { char cResponse = '\\0'; printf("\\na\\tTurn the AC on\\n");

#include <stdio.h> int main() { int iSelection = 0; float fTransAmount = 0.0; float fBalance = 100.25;

#include <stdio.h> int main(void) { const float INCHES_PER_FEET = 12; float height; char name[40]; printf("What is your name?: ");

用双引号将其打印将其打印在20个字符宽的字段中，整个字段用引号括起，名称在字段的右端。在20字符宽的字段的左端打印它，整个字段用引号括起来。将其打印在比名称宽三个字符的字段中。

#include <stdio.h> int main(void) {// printf("a a\\n"); printf("a \\n a \\n");

#include <stdio.h> int main(void) { int ageyears;/* age in years */ int agedays;/* age in days*/ //fromwww .yi ib ai .co m

#include <stdio.h> void functionA(void); void functionB(void); int main(void){ functionA();/*fromwww.yi i bai.com*/

#include <stdio.h> void my_function(void);/* C function prototyping */ int main(void){ printf("main.\\n");
