Answer 1

SoloProg also making char as c

Answer 2

Your condition are not correct in if statement you have to give condition you have written strings in double quotes remove them and take third input as a char type

Answer 3

#include <stdio.h>
int main() {
int a,b;
char c;
scanf("%i",&a);
scanf("%i",&b);
printf("your answer=");
scanf("%c",&c);
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);
return 0;
}

/* make c as char
and make operator in ''*/
