#include<stdio.h>
int main(){

int subject;
printf("Choose Your subject in which you have passed\n");
printf("If you have passed only Math then enter 1\n");
printf("If you have passed only Science then enter 2\n");

if (subject==1)
{
printf("You have passed only | Math | \n");
printf("You will get only 15 toffee!!");
}

else if (subject==2)
{
printf("You have passed only | Science | \n");
printf("You will get only 15 toffee!!");
}

else if (subject==4)
{
printf("You have passed both | Math | & | Science | \n");
printf("Hurray!! You will get only 50 toffee!!");
}

else
{
printf("You have entered Wrong! :(");
}

return 0;
}

Answer 1

If u enter a number accordingly it will show u no of toffee u get.
Eg. If u input 2
Then it will display 'passed in science' and 'you get 15 toffee'

Its just a basic problem to demonstrate the use of if else if else block .
Hope this helps.
Thanks.
