cgetch

getch(); does not pause the loop

I have this piece of code for instance:

while(true){
    printf("looping");
    getch();
}

Instead of waiting for user input on each loop, the loop just continues without me; printing

loop
loop
loop

until I close the program.

Is there a better way to read a single character ? All i really want to do is to have the user input a 'y' or a 'n'

Solution

  • Just use fgetc. I assume you're using this to break out of the loop, so to update your example:

    #include <stdio.h>

char iput;

while(true){
    printf("looping");
    iput = fgetc(stdin);
    if(iput == 'n')
      break;
}
