a lil help "for the lamer"

**datainjector** · 10-31-2002

Okay in the K&R book the question states that i should write a programm called entabs that replases tabs with a certain number of spaces ...
So this is my problem i tried this

Code:

while ( (c = getchar()) != EOF )
          if ( c == '\t' )
             printf("k");

since getchar is a bufferen function ...It only work if i press enter ...but i want that when the person presses tab it should print k ...The above code is just for ilustration purpose ...And i dont wanna use unbuffered getche() function because it is not ANSI ...What should i do is there a way to write my own function that does it for me ..if possible how ???

Try this :

Code:

#include <conio.h>
#include <stdio.h>

int main()
{
    char c;
    while (c != '1' ) //program terminates uppon pressing 1
    {
        if ( c == '\t' )
        {
            printf("k");
        }
    c = getch();
    }
    return 0;
}

The program end when you press "1"

I have already answered you in your other thread: There is no UNBUFFERED ANSI function for reading input.
