Pascal Triangle Program in C?

To Print Pascal Triangle in C

#include<stdio.h>

#include<conio.h>

long fact(int m); //function declaration

long fact(int  m)  // function definition

{

    int c;        // c is counter variable

    long result = 1;

   

    for( c = 1 ; c <= m ; c++ )

            result = result*c;

            return result;

}

void main()

{

    Int  i, n, c;

    clrscr();

    printf("How many rows you want to enter in pascal triangle?\n");

   

    scanf("%d",&n);

   

    for ( i = 0 ; i < n ; i++ )

    {

        for ( c = 0 ; c <= ( n - i - 2 ) ; c++ )

        printf(" ");

        for( c = 0 ; c <= i ; c++ )

            printf("%ld ",fact(i)/(fact(c)*fact(i-c)));

            printf("\n");

    }

    getch();

}

Note:

Pascal's triangle is a set of numbers arranged in the form of a triangle. Each number in a row is the sum of the left number and right number on the above row. If a number is missing in the above row, it is assumed to be 0. The first row starts with number 1.
