I want to write a code which take a,b then calculate one of these(- + / *) main operations and say the result
But i can’t
What can i do?!

Check for b == 0 before calculating
int q = a/b;
If b is greater than a then q will always be 0 due to integer division
your q should be double
double q = (double) a / b;
use the correct format specifier when printing it.
if(b==0){
printf("error");
else
printf("%d",q);
}
should be
if(b==0){
printf("error");
}
else {
printf("%d",q);
} you can skip curly brackets since you have only one line statement
Improve your understanding of C language and develop logic. You are making silly mistakes (you did the same in your last program)

You will eventually have to improve. Your target should be to become a better programmer not those exercise. Just keep on practicing and be focussed when solving exercises, you will improve.
#include <stdio.h>
#include <math.h>
int main() {
int a,b;
printf("what do you want to do?\n");
scanf("%d%d",&a,&b);
int q=a/b;
if(b==0)
printf("error\n");
else
printf("%d\n",q);
int p=a+b;
int m=a-b;
int s=a*b;
printf("%d\n%d\n%d",p,m,s);
return 0;
}
This works?
This is your code I have just made some changes so that you can see the output atleast. Parenthesis after if continuing till the end of else was wrong.
