In this C++ exercise, your are about to write C++ program to display a matrix as shown below. The diagonal of the matrix fills with 0. The lower side fills will -1s and the upper side fills with 1s.

0	1	1	1	1
-1	0	1	1	1
-1	-1	0	1	1
-1	-1	-1	0	1
-1	-1	-1	-1	0

 Solution:

#include<iostream>

#include<conio.h>

using namespace std;

   int main() 
    {

     int matrix[5][5]; 

     int i,j; 
     for(i=0;i<5;i++) //assign values to the matrix

        for(j=0;j<5;j++){

           if(i==j) matrix[i][j]=0;//if row=column=> fill the matrix with 0

           else if(i>j) matrix[i][j]=-1;//if row>columns=> fill matrix with -1
           else matrix[i][j]=1;//if row<columns=> fill matrix with 1

             }    

         for(i=0;i<5;i++){ //print the array
        for(j=0;j<5;j++)
            cout<<matrix[i][j]<<"\t";
        cout<<"\n";  
       }
     getch();
     return 0;
