how to wirte in cpp Program to print the first 10 lines of pascal’s triangle

Hello friends, Welcome to your Techgsr.co blog. And today in this article we will learn about how to wirte in cpp Program to print the first 10 lines of pascal’s triangle .So let’s go to our topic

#include <iostream.h>
#include <conio.h>
#include <iomanip.h>
long triangle(int x,int y);
int main()
{
clrscr();
const lines=10;
for (int i=0;i<lines;i++)
for (int j=1;j<lines-i;j++)
cout << setw(2) << ” “;
for (int j=0;j<=i;j++)
cout << setw(4) << triangle(i,j);
cout << endl;
getch();
}
long triangle(int x,int y)
{
if(x<0||y<0||y>x)
return 0;
long c=1;
for (int i=1;i<=y;i++,x—)
c=c*x/i;
return c;
}

This program does not take in any screen inputs from the user.It just prints out the first ten lines of the pascal’s triangle using the ‘cout’ command.
INPUT :
No input from the user for this program.
OUTPUT :
1 10 45 120 210 252 210 120 45 10 1
