Thread: My setup() function is being skipped.

Why is my setup() function skipped after the login_process() function is finished running? I am not able to go through and answer the questions specified by the setup() function?

Code:

#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <time.h>
#include <inttypes.h>

#define __STDC_FORMAT_MACROS

void login_process();
void setup();
void menu_and_startup();
void add_transferees();
void view_transferees();
void remit_money();
void time_display();
void display_information();
void thank_you_message();

Thanks for your response! I should have noticed the problem about the newline character and the scanf function! I have also fixed the unintialized variable. Initially, I just wasn't sure how I would use this variable.
