In this tutorial, we will learn about Program to Print Upper half and Lower half Triangle of Square Matrix in CPP (C plus plus).

#include<iostream>
 
using namespace std;
 
int main()
{
    int array[10][10];
	int k;
	int i;
	int j;

    
    cout<<"Please enter the size of the Matrix (MIN 3, MAX 5):";
    cin>>k;
    
    cout<<endl<<"Please enter the Matrix row wise:"<<endl;
    
    for(i=0;i<k;i++)
        for(j=0;j<k;++j)
            cin>>array[i][j];
    
    cout<<endl;
    
    for(i=0;i<k;++i)
    {
        for(j=0;j<k;++j)
        {
            if(i<j)
                cout<<array[i][j]<<" ";
                
            else
                cout<<"  ";
        }
        
        cout<<endl;
    }
    
    cout<<endl;
    
    for(i=0;i<k;++i)
    {
        for(j=0;j<k;++j)
        {
            if(j<i)
                cout<<array[i][j]<<" ";
            else
                cout<<" ";
        }
        cout<<endl;
    }
 
    return 0;
}
