Question

I am currently just learning C and for a project I need to read in integer inputs from the user. Currently I am using code that looks like this:

#include <stdio.h>
#include <stdlib.h>

int main(int argc, char *argv[])
{

    int a, b;

    printf("Please enter your first number");
    while((a = getchar()) != '\n') {
    }

    printf("test");

    return 0;
}

Im not sure how to get the number with getchar and then store it in a variable i can use.
Also I’m using = ‘\n’ in the while statement because I don’t really understand how EOF works (as in the K&R book) because whenever i use EOF i go into this loop i cant get out of.

Thanks for any advice anyone can offer.

You can use scanf.

Have a look at this example:

printf("Please enter your first number ");
int number=0;
scanf ("%d",&number);
