Thread: Blank screen, while executing the program

Dear All,

I am facing this problem right from the time when i first installed Turbo C_3, the compiler runs fine, but the execution screen is just blank with no error messages. its just a blank screen with no output, i checked the output file, is creating.

there are no errors in the program, and this is really annoying.

i am using Windows Xp, SP - 0 OS, i tried it on my laptop too which has SP_2, but still the same thing which makes me think i have to tweek something on the TC options before it. If so kindly let me know.

Please help me with this regard.

@rogester001 : cool, i took ur advice, got it installed, here's my sample programme,

Code:

#include<stdio.h>
void main()
{
int num1,num2,num3,sum;
float averag;
printf("Entre the three nos\n");
scanf("%d %d %d",&num1,&num2,&num3);
sum=num1+num2+num3;
averag=sum/3.0;
printf("sum = %d\n Average = %f\n",sum,averag);
}

Execution window shows this mess : Process returned 0 <0x0> Execution time : 0.000s
without actually producing any o/p, what might probably be the error?

Guessing the fix might be this: FAQ > Stop my Windows Console from disappearing everytime I run my program? - Cprogramming.com

Well guys, i tried getchar(); too earlier...but had no luck,i even tried to execute the example programs that come included in the software package, but had no luck even there. I used c programs while at college, had no problems then, in the same computer.

Sounds like some dodgy Turbo C compiler or library behaviour. What you've written should work fine.

Beware that getchar() blocks until you hit enter. So

Code:

c = getchar();

Will put whatever character you entered in c, but then it'll go straight through a subsequent getchar() because there's a newline waiting to be processed on stdin.

You shouldn't use getchar() for getting the numbers, but you could use it to block before exit to avoid the command prompt disappearing. Just make sure the previous scanf() eats the newline (put it in the format string). And should all be good.
