char b = "Maths";
char c = "maths and science";
printf("how many subject you are passing and enter valid subjets because we have only two subjects \n",subject);

scanf("%d",&a);
if (a==1)

else if (a == 3)
{
printf("OMG very very congratulation you won 45 rupees because you passed in maths and science both");
}
return 0;
}
NESTD if.
#include <stdio.h>int main(){int var1, var2;printf("Input the value of var1:");scanf("%d", &var1);printf("Input the value of var2:");scanf("%d",&var2);if (var1 != var2){printf("var1 is not equal to var2\n");//Nested if elseif (var1 > var2){printf("var1 is greater than var2\n");}else{printf("var2 is greater than var1\n");}}else{printf("var1 is equal to var2\n");}return 0;}
