Write a C program to generate Pascal’s triangle
.
Algorithm:
Step 1: Start Step 2: Read p value as integer Step 3: while(q<p) begin for r:40  3 * q to 0 decrement r by 1 for x: 0 to q increment x by 1 begin if((x == 0)  (q == 0)) binom = 1; else binom = (binom * (q  x + 1)) / x; print binom end ++q; end Step 4: Stop
Program:
#include <stdio.h> #include <conio.h> long factorial(int); void main() { int i, n, c; clrscr(); printf("Enter the number of rows\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(ic))); } printf("\n"); } getch(); } long factorial(int n) { int c; long result = 1; for (c = 1; c <= n; c++) { result = result*c; } return result; }
Input & Output:
Enter the number of rows 5 1 1 1 1 2 1 1 3 3 1 1 4 6 4 1
