My Solution

#include<stdio.h>
void res(int a, char b, int c){
    if(b == '+'){
        printf("%d + %d = %d",a,c,a+c);
    }
    else if(b=='-'){
        printf("%d - %d = %d",a,c,a-c);
    }
    else if(b=='*'){
        printf("%d * %d = %d",a,c,a*c);
    }
    else if(b=='/'){
        printf("%d / %d = %d",a,c,a/c);
    }
    else{
        printf("0");
    }
}
int main(void){
    int num1,num2;
    char giho;
    scanf("%d %c %d",&num1,&giho,&num2);
    res(num1,giho,num2);
    return 0;
}
