Thread: My setup() function is skipped.

My setup() function is skipped. I am not able to enter 'y' for yes 'n' and proceed through the rest of the code inside this function. Instead when the program is run, it just jumps to the the following function, which is menu_and_startup().

Code:

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

void startup_message();
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();

int main ()
{
    startup_message();
    
    login_process();
    
    menu_and_startup();
    
    return 0;
}

void startup_message()
{
    printf("Welcome to the newly introduced smsTransfer© (remittances through SMS text messaging)!\n");
    printf("a joint project of PioneerBank and Globe Telecom\n");
    
    printf("NOTES:\n");
    printf("1. Both the transferers and the transferees must have active accounts with both companies to take part in this service.\n");
    printf("2. If this is your first time using the service, please add your account information immediately after logging into this service.\n\n");
}
