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.h> int main (void) { int answer, result; answer = 100; result = answer - 10; printf ("The result is %i\\n", result + 5);

#include <stdio.h> int main (void) { int sum; // compute result sum = 25 + 37 - 19; // display result

正整数n的阶乘由n!表示 并定义如下： n! = 1 x2 x..... xn 例如： 0! = 1 1! = 1 2! = 1 x 2 = 2

#include <stdio.h> int main(){ int counter = 100; unsigned long int sum = 0; for (int i = 1; i <= counter; i++) {

素数是一个正整数，只能由1和它本身整除。 #include <stdio.h> #include <math.h>

#include <stdio.h> int main() { long int counter = 1234, temp, remainder, reverse; temp = counter; reverse = 0;

#include <stdio.h> int main(void){ char letter = 0;// Stores a character printf("Enter an uppercase letter:");// Prompt for input

可以通过字符常量为char类型的变量指定初始值。字符常量是在单引号之间写入的字符。看看下面的例子：
