scanf challenge

Hello!

here is my programm in "C" language.

#include <stdio.h>

void getvalue(int *value)
{
int n;
n = scanf("%d", value);

}

int main()
{
int num;
getvalue(&num);

return 0;
}

what did it actually do, it take a number and read it through key board. if we press just "enter key" and give no input it ignore the "enter key" and continuously asks for input. I wants that it should leave the command and get back to main. i mean if we press enter it should not ask again for input again.

Why do you need another function to do this?? That's terrible programming as it uses too much memory. Just have scanf in your main function. And the problem with your program is that your getvalue function doesn't return a value to the main function. I suggest you go to this website to learn C.

Then dont use scanf. Scanf call will block till u give a input. Try getchar() or getch() or gets()
