Alternate Elements of 2-D Array

C++ PROGRAMS

In this program the number of rows, columns and the elements of the 2-D Array are entered by the user. The output is the arranged Array (just like the output of the previous program 2-D Array) and the Alternate Elements of the Array starting from the first element.

The Code consists a user-defined function in which the Array, number of rows and number of columns are passed as arguments.

Code:

#include<iostream.h>

#include<conio.h>

void alternate(int A[10][10], int r, int c)

{

int i,j;

for(i=0;i<r;i++)

{

 for(j=0;j<c;j++)

 {

  if((i+j)%2==0)

  cout<<A[i][j]<<" ";

 }

} 

}

void main()

{

clrscr();

int i,j,r,c,A[10][10];

cout<<"Enter the number of Rows: ";

cin>>r;

cout<<"Enter the number of columns: ";

cin>>c;

for(i=0;i<r;i++)

{

 for(j=0;j<c;j++)

 {

  cin>>A[i][j];

 }

}

clrscr();

cout<<"Your Array is: \n";

for(i=0;i<r;i++)

{

 for(j=0;j<c;j++)

 {

  cout<<A[i][j]<<" ";

 }

 cout<<"\n";

}

cout<<"\nAlternate Elemnts of Array are: ";

alternate(A,r,c);

getch();

}
