篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了打卡第二十三天相关的知识，希望对你有一定的参考价值。
要求编写一个简单计算器程序，可根据输入的运算符，对2个整数进行加、减、乘、除或求余运算。题目保证输入和输出均不超过整型范围。
一、
1.运用if语句，将每种运算都写出来
二、
三、
#include<stdio.h>
int main()
int a,b;
char c;
scanf("%d %c %d",&a,&c,&b);
if(c==\'+\')
printf("%d",a+b);
else if(c==\'-\')
printf("%d",a-b);
else if(c==\'*\')
printf("%d",a*b);
else if(c==\'/\')
printf("%d",a/b);
else if(c==\'%\')
printf("%d",a%b);
else
printf("ERROR");
return 0;
四、
#include<stdio.h>
int main()
int a,b;
char c;
scanf("%d %c %d",&a,&c,&b);
if(c==\'+\')
printf("%d",a+b);
else if(c==\'-\')
printf("%d",a-b);
else if(c==\'*\')
printf("%d",a*b);
else if(c==\'/\')
printf("%d",a/b);
else if(c==\'%\')
printf("%d",a%b);
else
printf("ERROR");
return 0;
