Thread: Why this quiz game not working

hello friends,

I am trying to make a quiz game

but after you press 'S" and register your name
then when i press Y so that the quiz start its going back to main menu

but when i press shift y in my keyboard the quiz starts
but even though i select right answer it shows you are wrong?

but when i select shift and the correct choice it works
so somehow toupper() function not working ?

here is my code just look into main function

Code:

#include <stdio.h>#include<conio.h>
#include<ctype.h>
#include <stdlib.h>
#include<string.h>


void show_record();
void reset_score();
void help();
int main(){
int countr,r,rl,count,i,n;
float score;
char choice;
char playername[20];
mainhome:
    system("cls");
    printf("\t\t\tC PROGRAM QUIZ GAME\n");
    printf("\n\t\t_____________________________________________");


    printf("\n\t\t\t      WELCOME  ");
