Help for the desperate ...?

Hello all...

I have been working on this for about a week now, which is probably pretty pathetic to admit. This assignment is for a beginners C Ansi programming class. I have created this using the "for", "do" and "while" loops, and am missing the same thing every time.

Here is my problem:

When the user enters a negative number, an error message is initiated. The program is then supposed to ignore that and prompt the user for the number again. For example, if it were positive value # 3, and a negative number was entered, then the negative number would be ignored, and the program would prompt for #3 again.

I'm sure this is something stupid I keep doing over again, since I keep coming up with the same anwer, but I would truly appreciate any insight you could give me. Even if you were to simply ask me a question to put me in the right direction. I seem to have entered my own loop, and can't get out.

Thanks in advance!!!!!
Very humbly .....

here is the code:

#include <stdio.h>
void main (void)

{
/*------------Declare Variables--------------------------*/

int value,x;
int tot_val = 0;
int pos_int = 0;
float average;

/*------------Describe what the program does-------------*/


printf("\nThis program calculates the average of as many numbers as you wish to enter.");


/*------------Give instructions to the user--------------*/


printf("\n\nFirst, enter the number of values to process:");

scanf("%i", &value);

printf("\nNow enter the %i numbers to be averaged.\n\n",value);



/*------------Enter the loop information----------------*/

for (x=1; x <= value; x++)

{
printf("Enter the positive integer #%i: ", x);

scanf ("%i", &pos_int);

tot_val=tot_val + pos_int;

{

if(pos_int < 0 )

printf("\n***Invalid entry. Value must be positive.\n");
continue;

}

pos_int++;
}

/*-------------Figure the average--------------------- */



average = (float)tot_val / value;


printf("\n\nThe average of the %i numbers entered is %.2f\n.",value,average);

}//end main

Hi kmr6655,

try this instead

Code:

for (x=1; x <= value; x++){
                    
   printf("Enter the positive integer #%i: ", x);
   scanf ("%i", &pos_int);

   while ( pos_int < 0 ){
      printf( "Please enter a positive integer!\n" );
      scanf( "%i", &pos_int );
   }
   tot_val=tot_val + pos_int;
   pos_int++;
}

The user will stay in the while loop until they enter in a positive number.

Hope this helps!

[edit]Change void main(void) to int main(void)and add return 0; at the end of main.
main always returns an int.[/edit]

Just wanted to say thank you for your help.....

It hung for some reason, so I added the printf statement, and it works like a charm.

Much appreciated!!!!
