Thread: Something is wrong???

I'm trying to prompt and print principal,rate,and days; and compute and display interest. The following doesn't seem to work. Any thoughts for correcting? The copile error I get on the last print is statement missing and after that I get a warning that "interest" is assigned a value that is never used. DW

#include<stdio.h>

void main(void)
{

int principal;
int rate;
int days;
int interest;

/* Prompt to enter principal*/

printf("\nEnter principal ");

scanf("%d",&principal);

/*Prompt to enter rate*/

printf("\nEnter rate ");

scanf("%d",&rate);

/* Prompt to enter days*/

printf("\nEnter days ");

scanf("%d",&days);

/*Print out the interest charge*/

interest=(principal*rate*days)/365

printf("\nThe interest charge is %f", principal*rate*days/365);



}

use [ code ] [ /code ] tags
and its

Code:

int main(void){

  ...
  return 0;
}

Code:

printf("\nThe interest charge is %f", principal*rate*days/365);

should be

Code:

printf("\nThe interest charge is %d", interest);

While I agree with sand_man that you don't need to reuse the formula when you are storing the result in interest, I also noticed that you left a semicolon off of this line:

Code:

interest=(principal*rate*days)/365

There is a symbol ( missing, it should go:
interest=(principal*rate*days)/365 ; with the ; symbol

instead of
interest=(principal*rate*days)/365

that is why it says "statement missing"

and also the correction sand_man made is needed

Shouldn't interest, rate, and principal also all be floats? Otherwise there will be serious rounding errors...
