Thread: cant figure out where to put the loop....

Well I finally got my basic accoutning program done, but I want it so that it doesnt quit right after it computes the info (so people dont have to use command everytime....

I cant figure out where to put

Code:

while( (c=getchar()) != EOF && c != '\n' ){ }

no matter where i think is appropriate it still just ends the program once computing is done...

Code:

#include <stdio.h>


int PMR ( int input );
int ROA ( int input );
int WC ( int input );
int c;
float pmr;
float ni;
float ns;
float roa;
float avg;
float wc;
float ca;
float cl;


int main()
{
int input;

printf( "Welcome to the Accounting Calculator v.1\n" );
printf( "NOTE: DO NOT USE COMMAS! USE PERIOD TO PUT IN DECIMALS!\n" );
printf( "Select from one of the following options by entering the number it corresponds to\n");
printf( "\n");
printf("1. Profit Margin Ratio\n");
printf("2. Return on Assets\n");
printf("3. Working Capital\n" );
printf("4. Exit program\n");
printf("Selection: ");
scanf("%d", &input);
switch ( input ) {

	case 1:
		 PMR( input );
		break;
	case 2:
		ROA( input );
		break;
	case 3:
		WC( input );
		break;
	case 4:
		printf("Thanks you for using the accounting calculator\n");
		break;
	default:
		printf("Bad input, quitting!\n");
		break;

	}
}

int PMR ( int input )
{
printf( "Enter the Net income\n" );
scanf("%f", &ni);
printf( "Now enter the Net sales\n" );
scanf("%f", &ns);
printf( "Your profit margin ratio is " );
pmr = ni/ ns;
pmr = pmr* 100;
printf("%.2f", pmr);

printf( "%%\n" );
printf( "That means you are making %.2f cents off each dollar\n");
printf( "press any button to exit the program\n" );
while( (c=getchar()) != EOF && c != '\n' ){ }
}
	
int ROA ( int input )
{
printf( "Enter the Net income\n" );
scanf("%f", &ni);
printf( "Now enter the average of total assets\n" );
scanf("%f", &avg);
printf( "Your Retun on assets is " );
roa = ni/ avg;
roa = roa* 100;
printf("%.2f", roa);

printf( "%%\n" );
}
	
int WC ( int input )
{
printf( "Enter the Current assets\n" );
scanf("%f", &ca);
printf( "Now enter the Current liabilities \n" );
scanf("%f", &cl);
printf( "Your Working capital is " );
wc = ca- cl;
printf("%3.f\n", wc);
printf( "press any button to exit the program\n" );
getchar ();
return 0;

while( (c=getchar()) != EOF && c != '\n' ){ }
}

awesome... got it thx
