#include stdio.hint main(void) {const int minperhour = 60;int minutes, hours, mins;//printf(Enter the number of minutes to convert: );

#include stdio.hint main(void){char ch;printf(Please enter a character.\\n);scanf(%c, ch);/* user inputs character */

#include stdio.hint main(void){unsigned int un = 3000000000; /* system with 32-bit int */short end = 200;/* and 16-bit short*/

这里是一些例子。数字值指数表示法1,000,000,0001.0e9123,0001.23e5322.563.2256e20.000056

#include stdio.h int main(void) { int a, b; a = 5; b = 2;/* line 7 */ b = a;/* line 8 */ a = b;/* line 9 */

#include stdio.h int main(void) { int a, b; a = 5; b = 2;/* line 7 */ b = a;/* line 8 */ a = b;/* line 9 */

转换说明符有两部分：第一个字符是百分号(%)，第二个是一个特殊字符，告诉程序如何转换数据。

要打印变量的内容，请使用printf()函数并指一些新格式选项。#include stdio.h

以下代码声明了两个变量：一个整数和一个字符数据类型。创建两个变量后，代码会将它们初始化为特定值。\\0称为NULL字符。

浮点数包括有符号和无符号的小数和小数。有符号包括正数和负数。无符号数字只能包含正值。

#includestdio.hint main (void){printf(The next largest even multiple of %i and %i is %i.\\n, 365, 7, 365 + 7 - 365 % 7);

#include stdio.hint main (void){int n, triangularNumber;triangularNumber = 0;for (n = 1; n = 200; n = n + 1)

例如，它会将18天转换为2周，4天。以下列格式显示结果：18天是2周，4天。使用while循环允许用户重复输入日期值。

#include stdio.hint main(void){int count, sum;int n;printf(Enter the upper limit: );

#include stdio.hvoid showCube(double x);int main(void){double val;printf(Enter a floating-point value: );

#include stdio.hint main(void){int x = 100;printf(dec = %d; octal = %o; hex = %x\\n, x, x, x);

#include stdio.hint main(void){int jane, tarzan, cheeta;cheeta = tarzan = jane = 68;printf(cheetatarzanjane\\n);

#include stdio.hint main(void){int n = 0;size_t intsize;intsize = sizeof (int);printf(n = %d, n has %zd bytes; all ints have %zd bytes.\\n, n, sizeof n, intsize );

#include stdio.hint main(void){int top, score;top = score = -(2 + 5) * 6 + (4 + 3 * (2 + 3));
