Hi guys,
I was just writing a wee program to calulate APR on a credit card, i was going to use a case statement, so did a bit of reading and looked at some examples, seems simple but i can't get mine to work. Could you help?
My code:
Code:
#include <stdio.h>
int main()
{
float balance, apr, apr_dec, interest;
int term;
// Ask for balance on card:
printf("Enter the balance of the card.\n");
scanf("%f",&balance);
printf("Card Balance = £%.2f\n", balance);
// Get Rate:
printf("Enter the current interest rate (APR) in percent.\n");
scanf("%f", &apr);
printf("Apr = %.2f\%\n", apr);
apr_dec = apr / 100;
// Get Term
printf("Enter the Term in Months.\n");
scanf("%d", &term);
printf("Term = %d months\n");
interest = (apr_dec * balance) / 12;
printf("interest = £%.2f\n", interest);
int selection ;
printf("Enter the type of payment : \n") ;
printf("1: minimum payment\n") ;
printf("2: fixed amount\n") ;
printf("selection : ");
scanf("%d", &selection) ;
switch (selection) {
case '1' :
printf("Case 1");
break ;
case '2' :
printf("Case 2");
break ;
}
printf("something\n");
}
When i run the above i get this output:
Code:
Enter the balance of the card.
1000
Card Balance = £1000.00
Enter the current interest rate (APR) in percent.
9.9
Apr = 9.90%
Enter the Term in Months.
30
Term = 30 months
interest = £8.25
Enter the type of payment :
1: minimum payment
2: fixed amount
selection : 1
something
So it won't do anything in the switch. Any ideas?
Thanks in advance.
Kai.
