question about loop tutorial....

Hey on the tutorial section theres this code on loops.

Code:

---

{                //The loop goes while x<100, and x increases by one every loop
  for(int x=0;x<100;x++) //Keep in mind that the loop condition checks
  {    //the conditional statement before it loops again.
    //consequently, when x equals 100 the loop breaks   
    cout<<x<<endl;          //Outputting x
}
  return 0; 
}

---

Now i need to write some code that displays a question a set amount of times, i was thinking i could use this, but for some reason i cant seem to work out where the loop content goes. Anyone help me on this?

Code:

---

for (...)
{
    // loop content goes here
}

Hey thanks, now my second question..why when i compile does it just flash up on the screen in a black box then dissapear, im using c++ 5.0, borland. Thanks.

because you aren't running the program from command prompt. your program doesn't wait for input, it just does its thing and quits.

try going into the command prompt, go to the program directory and execute it

Re Q2
It's in the FAQ

Code:

---

#include <iostream.h>
int main()
{
 int marks[4];
 int i;
 while(i<5)
 {
    cout<<"Enter the first mark"<<endl;
    cin>>marks[1];
    i++;

  }

  cout<<marks[1];
 return 0;
}

Ok heres the deal so far, basically i need somehow to make it so that it asks a question, you type the mark, goes into [1], then displays the contents of [1]. Hmmm now im stuck as how to fill the array by looping. bah..please help! Thanks.

Code:

---

#include <iostream>
using namespace std;

int main() {
 int marks[4];
 int i = 0;
 while(i<5) {
  cout << "Enter the first mark" << endl;
  cin >> marks[i];
  cout << marks[i];
  i++;
 }
 return 0;
}

Wrong.

Array indexes start at 0 and end at size-1. So for the above array, we can access marks[0] thru marks[3]. And since the variable 'i' loops to 4, we end up going off the end of the array (access violation).

I hurried through that anyway, spent 3 and a half seconds on it :D .
