it should display the timer and questions.plzz help i am new to programming

here is the code

void addtion()
{
     int firstran,secondran,num1,num2,sum,in1,ans,count=0,right=0,worng=0,score=0;
     cout<<"\t\t\t\tADDTION\n";
                               for(int k=0;k<80;k++)
                              {
                                  cout<<"-";
                                  delay1();
                              }
                              cout<<"\n\nREADY????";
                              delay1();
                              cout<<"\n\nENTER A CHAR WHEN READY.....\n";
                              cin>>in1;
                              system("cls");
                              cout<<"\t\t\t\tLEVEL 1\n";

[bugme]

just give me some ideas or procedure to do it

[m4ster r0shi]

#include <iostream.h>
#include <conio.h>
#include <stdlib.h>

int main()
{
    int time_limit=10; //seconds
    int ans;
    bool ans_ready=false;

    int seconds=0;
    int prev_seconds=0;

    int start=clock();

    while (true)
    {
        if (kbhit())
        {
            cin>> ans;
            ans_ready=true;
        }

        if (ans_ready)
        {
            cout << "your answer: " << ans << endl;
            ans_ready=false;
        }

        seconds=((clock()-start)/CLOCKS_PER_SEC);

        if (seconds>prev_seconds)
        {
            cout << "seconds elapsed: ";
            cout << seconds << endl;
            prev_seconds=seconds;
        }

        if ( seconds>=time_limit )
        {
            cout << "time is up!" << endl;
            if (seconds>time_limit)
            {
                cout << "your last answer was given";
                cout << " too late... it will be ignored";
                cout << endl;
            }
            break;
        }
    }

    system("pause");
    return 0;
}

thanx m4sterr0shi i'll try your program now :D

[bugme]

wat is kbhit() function use for??

wat clock( ) function returns??

srry i'm new to programming ,can someone post a link for clock tutorial

i dont know how it works

[m4ster r0shi]

to check if there is data in the input buffer

[bugme]

thanx again m4sterr0shi

does it work on DEV C++

[m4ster r0shi]

http://cplusplus.com/reference/clibrary/ctime/clock/

if you don't understand something try googling or searching it in this site

[bugme]

ok thanx

i have used clock() function the program runs good,but i want to display the time at the corner of the screen and also display the questions at the same time
is there any way to do that??

[m4ster r0shi]

Mmmm... This may be tricky... I'm afraid you'll have to resort to multithreading. Have a main thread that displays the questions and gets the answers and another one that handles the clock. You may also have to use some windows API to change the position of the console cursor.
