How to make pascal's triangle using for loop in c++

This C++ Program which prints pascal’s triangle. The program takes number of rows as input and uses nested loops to print pascal’s triangle. The first inner loop creates the indentation space and the second inner loop computes the value of binomial coefficient, creates indentation space and prints the binomial coefficient for that particular column.Here is source code of the C++ program which prints pascal’s triangle. The C++ program is successfully compiled and run on a Linux system. The program output is also shown below.

IF YOU ARE USING MODERN COMPILERS LIKE DEV C++ AND CODEBLOCKS

#include<iostream>

using namespace std;

int main()

{

    int rows;

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

    cin >> rows;

    cout << endl;

    for (int i = 0; i < rows; i++)

    {

        int val = 1;

        for (int j = 1; j < (rows - i); j++)

        {

            cout << "   ";

        }

        for (int k = 0; k <= i; k++)

        {

            cout << "      " << val;

            val = val * (i - k) / (k + 1);

        }

        cout << endl << endl;

    }

    cout << endl;

    return 0;

}

IF YOU ARE USING OLD COMPILERS LIKE TURBO C++

#include<iostream.h>

int main()

{

    int rows;

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

    cin >> rows;

    cout << endl;

    for (int i = 0; i < rows; i++)

    {

        int val = 1;

        for (int j = 1; j < (rows - i); j++)

        {

            cout << "   ";

        }

        for (int k = 0; k <= i; k++)

        {

            cout << "      " << val;

            val = val * (i - k) / (k + 1);

        }

        cout << endl << endl;

    }

    cout << endl;

    return 0;

}
