Realisation Pascal triangle in C++ (console)

Console Pascal triangle

Examples:

Code:

#include #include <conio.h>

using namespace std; int main() { long int r, k, max; //rzad, kolumna

cout << "This program prints the Pascal triangle\n";
cout << "enter level: ";

cin >> r;

r = r - 1;
k = r;
max = r;

long int tab[ r + 1 ][ k + 1 ]; //create two-dimensional tables
for( r = 0; r <= max; r++ )
{
    for( k = 0; k <= max; k++ )
    {
        tab[ r ][ k ] = 0;
    }
} // clean the whiteboard

tab[ 0 ][ 0 ] = 1;
tab[ 1 ][ 0 ] = 1;
tab[ 1 ][ 1 ] = 1;

for( long int r = 2; r <= max; r++ )
{
    for( long int k = 0; k <= r; k++ )
    {
        if( r == k ) tab[ k ][ r ] = 1;
        
        if( k == 0 ) tab[ k ][ r ] = 1;
        
        tab[ r ][ k ] = tab[ r - 1 ][ k - 1 ] + tab[ r - 1 ][ k ];
    }
} //calculation of cell values

for( r = 0; r <= max; r++ )
{
    for( k = 0; k <= r; k++ )
    {
        cout << tab[ r ][ k ] << " ";
    }
    cout << endl;
} //writing the result on the screen

r=2;
k=0;
tab[ r ][ k ] = tab[ r - 1 ][ k - 1 ] + tab[ r - 1 ][ k ];

cout << tab[2 ][ 2 ] << " ";
