Question
i did this question.
car              discount
800cc               8%
1000cc              5%

write a prog to calculate the net amount.
input: cc, price, discount
print: cc, price, discount, net amount.

but when i compile,there r no errors or warnings. but the if-else part wasnt executed. y?
please help me.

#include<stdio.h>

int main(void)
{

  int cc;
  float price;
  double discount;



  printf("Enter your car cc:");
  scanf("%d",&cc);

  printf("Enter the price of your car:");
  scanf("%f",&price);

  if(cc=800)
     discount=price-(0.05*price);
  else
     discount=price-(0.08*price);

  return 0;
}

Answer
Change:
>if(cc=800)
To:
if(cc == 800)

Note that you have used '=' which is an assignment operator in the condition. Because of that value of cc is getting changed to 800.
Instead use the '==' operator which tests for equality.

Hope this helps....
