Hi guys - new to the board ( and C in general)...so go easy

I'm currently working on the following code for a musical test and, basically, I'd like to add an option for the user to restart the test from within the program ( rather than running the .exe again).
I'll print something like "Do you want to run the test again? Y/N?"
Do I use another if/else statement ( like, ..if user_input == 'Y' then ...re-run the for loop - or however you code it - else if user_input =='N' then...quit=TRUE?

I know it's a simple question, but I can't seem to suss it.

Thanks in advance for any help!

include "midi_lib.h"

int pitch_array[5] = {60,62,64,65,67}; //Range of notes ( C D E F G ) stored in an array//
int count = 0;  //Variable called count - counts through notes in the array//
int quit = FALSE;  //Variable called quit -  starts and ends loop//
int timbre = 1; //Variable called timbre - midi channel allocation//
int pause_val = 1000; //Variable called pause_val - determines note length//
char user_input; //Variable called char -  keyboard input from user//


 //Changes timbres from initial value 1//
