Hi All,

I'm trying to figure out how I can test a condition (negative or positive number) and then have it go back into the for loop. What I'm trying to accomplish is if the user enters a negative number the user will get an error and then should be re-prompted for a positive number like this:

First, enter the number of salaries to process: 4

Now enter the 4 salaries to be averaged.

Enter salary #1: 10000
Enter salary #2: 8000
Enter salary #3: -20000
*** Invalid entry. Salary must be positive. ***
Enter salary #3: 25000
Enter salary #4: -3333
*** Invalid entry. Salary must be positive. ***
Enter salary #4: 52000

The Average of the 4 salaries entered is: $ 23750.00

The Total of the 4 salaries entered is: $ 95000.0

Any help would be very appreciated:

Code:
#include <stdio.h>

int main(void)
{
    
      
    int     i, salary;
    int     numb_salaries = 0;
    int     sal_total = 0;
    float   total = 0;
    
    
    printf("Welcome to the  Employee Calculator Program. \n\n");
            
    printf("This program calculates the average and total of as ");
    printf("many employee salaries as you wish to enter. \n\n");
    
    printf("First, enter the number of salaries to process: ");
    scanf ("%i", &numb_salaries);
    
    printf("\nNow enter the salaries to be averaged. \n\n");
    
            /*  Enter for loop  */
                
            for (i = 1; i <=numb_salaries; ++i)
            {
                
                printf("Enter salary #%i: ",i);
                scanf ("%i", &salary);
                sal_total = sal_total + salary;
                
                    if ( salary < 0 )
                        salary = -salary;
                                
                printf("*** Invalid entry. Salary must be positive. *** ");        
                
                              
                
            }
    
            printf ("Thanks for using the program.\n\n");
    
            getchar(); /* Pause output */

            return (0);
}
