C Program to Create a Menu Driven Calculator

Program :-

#include < stdio.h >
main () {
    int a,b;
    int c,m;
    do{
         printf("\n enter the operands");
         scanf("%d%d",&a,&b);
         printf("enter the operations :1.addition 2.Subtraction 3.Multiplication 4.Division  5.Reminder");          scanf("%d",&c);
         if(c == 1){
                printf("%d + %d=%d",a,b,a+b);
         else if(c == 2)
                printf("%d - %d=%d",a,b,a-b);
         else if(c == 3)
                printf("%d * %d=%d",a,b,a*b);
         else if(c == 4)
                printf("%d / %d=%d",a,b,a/b);
         else if(c == 5)
                printf("%d % %d=%d",a,b,a%b);

         else

                printf("invalid option");

         printf("do you want to continue ?,if yes then enter 1 else 0);

         scanf("%d",&m);

        }

        while(m == 1);

}

Output :-

enter the operands
4
5
enter the operations :1.addition 2.Subtraction 3.Multiplication 4.Division  5.Reminder
1
4 + 5 = 9
do you want to continue ?,if yes then enter 1 else 0
0
