c语言的差

❶ 用c语言编写(计算两个整数的和、 差、积、商与余数

代码一：

#include<stdio.h>

int main(void)

{

int num1, num2;

scanf("%d%d",&num1,&num2);

printf("%d + %d = %d ",num1,num2,num1+num2);

printf("%d - %d = %d ", num1, num2, num1-num2);

printf("%d * %d = %d ", num1, num2, num1*num2);

if (num2) printf("%d / %d = %g ", num1, num2, (double)num1/num2);

else printf("ERROR ,DIVBYZERO ");

printf("%d %% %d = %d ", num1, num2, num1%num2);

return 0;

}

代码二：

#include <stdio.h>

void main()

{

int x, y;

printf("please enter a,b,c:");

scanf("%d,%d",&x,&y);

printf(" x+y=%d ",x+y);

printf("x-y=%d ",x-y);

printf("x*y=%d ",x*y);

printf("x/y=%d ",x/y);

printf("x%%y=%d ",x%y);

}

下图为C语言算术运算符：

(1)c语言的差扩展阅读：

算术运算符实例：

#include <stdio.h>

main()

{

int a = 21;

int b = 10;

int c ;

c = a + b;

printf("Line 1 - c 的值是 %d ", c );

c = a - b;

printf("Line 2 - c 的值是 %d ", c );

c = a * b;

printf("Line 3 - c 的值是 %d ", c );

c = a / b;

printf("Line 4 - c 的值是 %d ", c );

c = a % b;

printf("Line 5 - c 的值是 %d ", c );

c = a++;

printf("Line 6 - c 的值是 %d ", c );

c = a--;

printf("Line 7 - c 的值是 %d ", c );

}

❷ C语言中求两个数的差程序如何编写

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char *argv[]) {
int a,b;
printf("请输入a和b两个数，并采用，分隔:");
scanf("%d,%d",&a,&b);
printf("a+b=%d",a+b);
return 0;
}
