Adding & Displaying Two Dimensional Array

Posted on 2011-03-15

Can somebody tell me what I'm doing wrong?  I want to enter five start/finish times into a two-dimensional array, and get them to print out:
#include <iostream>
#include <stdlib.h>

using namespace std;
const int FINISH = 2;
const int START = 5;
void getData(int arr[][FINISH]);
void displayData(int arr[][FINISH]);

int i,j;
int main()
      int timeArray[START][FINISH];
      cout << endl << endl << endl;

      return 0;

// used to prompt user to fill array with values
void getData(int arr[][FINISH])
      cout << "Enter 5 start/finish times." << endl
        << "One at a time when prompted: " << endl;

         cout << endl;

   for(int i = 0; i <= 4; i++)
      cout << "Enter start[" << i + 1 << "]: ";
      cin >> arr[i][j];

	  for(int j = 0; j <= 0; j++)
		  cout << "Enter finish[" << j + 1 << "]: ";
		  cin >> arr[i][j];

      cout << endl;
}// end getData()
// used to display array contents
void displayData(int arr[][FINISH])
	cout << endl << endl;
      for (int i = 0; i < START; i++)
            for (int j = 0; j < FINISH; j++)
                  cout << arr[i][j] << " ";
            cout << endl;
}// end displayData()

Open in new window

The "j" part is not counting properly, and it won't display properly...

Why do you have this:

for(int j = 0; j <= 0; j++)
    cout << "Enter finish[" << j + 1 << "]: ";
    cin >> arr[i][j];

Open in new window

I would have expected to see this (where j had been initialized to zero):
cout << "Enter finish[" << j + 1 << "]: ";
cin >> arr[i][j + 1];

>> for(int j = 0; j <= 0; j++)

Is the upper bound correct here ? The loop would only iterate once.

In the line 38 you are using the variable 'j', which has not been initialized either declared yet.
Get the i and j variables declaration out of the for statement and give it a try.
