Hi there everyone. i'm doing a c++ program using DEV. i'm making a quiz program but i wish to add a countdown timer on the cmd at the same time, the user can do the quiz. The timer is shown on the screen and when the time reaches 30mins, the quiz is automatically finish and end. Can anyone help me out here? Here's my code
Code:
#include <iostream>
#include <fstream>
#include <cstdlib>
#include <conio.h>
#include <iomanip>
#include <ctype.h>
#include <cstring>
using namespace std;
int quiz1();
int quiz2();
void diagram1();
void diagram2();
void diagram3();
int main()
{
quiz1();
quiz2();
getch();
}
int quiz1()
{
cout<<"Quiz 1 Basic Concepts of Circuit Theory"<<endl<<endl;
cout<<"Please Key In Your Answers In Simplified SI Units shown as the table on the next page."<<endl<<endl;
cout<<"Press Any Key To Start The Quiz"<<endl;
getch();
system("CLS");
ifstream inputquiz1("quiz1.txt",ios::in);

char q1[10][999],ans1[10][999],realans1[10][999];
int a;
for(int i=0;i<10;i++)
{
inputquiz1.getline(q1[i],999);
inputrealans1.getline(realans1[i],999);
}
for(int i=0;i<10;i++)
{
cout<<"s = second(s)\t"<<"v = volt(s)"<<endl;
cout<<"a = ampere(s)\t"<<"ohm = ohm(s)"<<endl;
