I am trying to build an address book program. It has two options so far, it reads the addresses and prints them. they are accessible through a menu in the main function. Everything works fine but for the address I need more than 1 word, separated by space, so I tried using the getchar() function. The problem is that the compiler simply skips it. I am sure it's not the compiler, since I've tried several different ones. all resulting with the same problem. The problem-causing getchar() is in the InputContact function.
Any ideas/suggestions are highly appreciated.
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#define M 41 // Number of Chars for Firs-Last Name
#define N 101 // Number of Chars for Address
#define C 7 // Number of Chars for Postal Code
#define P 11 // Number of chars to be held in Phone Number
#define MAX 10 //maximum number of records
