Thread: Arrays

i want to load arrays and display arrays that will have numbers 1-15 in this format

1 2 3 4 5
6 7 8 9 10
11 12 13 14 15

i have got 2 functions
i will load arrays n second will display

[code]

void loadArray()
{
int r, c, cnt=1;

for( r=0; r<5; r++ )
for( c=0; c<5; c++ )
data[r][c] = cnt++;
}

void displayArray( )
{
int r, c, temp;

cout << "The 5 x 5 2D array:\n\n";

for (r=0;r<5;r++)
{
for(c=0;c<5;c++)
{
cout << " " << data[r][c];
}
}

displayArray();
getchar();

pause();
}
i want to display arrays when ever i call func DisplayArrays();

That is only a 5 x 3 Matrix. Try changing some of the loops accordingly.

i meant 5x5 array that will count upto 25

people help!

This is how you may want to write it. If you want them on separate lines simply put an cout << endl; after the end of the outter for loop when displaying. Looking at my code you should be able to see your mistakes. Need anymore help let me know.

Code:

#include <stdio.h>
#include <iostream.h>

void loadArray( int data[5][5] )
{ 
     int r, c, cnt = 1;
     for( r=0; r<5; r++ )
     {
         for( c=0; c<5; c++ )
         {
              data[r][c] = cnt++;
         }
     }
} 

void displayArray( int data[5][5] )
{ 
   int r, c, temp;

   cout << "The 5 x 5 2D array:\n\n";

   for (r=0;r<5;r++)
   {
      for(c=0;c<5;c++)
      {
         cout << " " << data[r][c];
      }
   }
}

int main( void )
{
  int Array[5][5];

  loadArray( Array );
  displayArray( Array );

  system("pause");

  return( 0 );
}
