C Program To Print Pascal Triangle

In this blog, you will learn how to print Pascal triangle.

Introduction

• In this blog, I am going to explain how to print a Pascal triangle.

Software Requirements

• Turbo C++ or C. 

Programming 

#include < stdio.h >
long factorial(int);
int main()
{
    int i, n, c;
    printf("Enter the number of rows you wish to see 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 ", factorial(i) / (factorial(c) * factorial(i - c)));
        printf("\n");
    }
    return 0;
}
long factorial(int n) {
    int c;
    long result = 1;
    for (c = 1; c <= n; c++) result = result * c;
    return result;
}

Explanation

• With the help of programming given above, Pascal triangle can be printed by giving the number of rows by the user.
