Write a C program to display Pascal's triangle

Pictorial Presentation:

Sample Solution:

C Code:

#include <stdio.h>

void main()
{
    int no_row,c=1,blk,i,j;
    printf("Input number of rows: ");
    scanf("%d",&no_row);
    for(i=0;i<no_row;i++)
    {
        for(blk=1;blk<=no_row-i;blk++)
        printf("  ");
        for(j=0;j<=i;j++)
        {
            if (j==0||i==0)
                c=1;
            else
               c=c*(i-j+1)/j;
            printf("% 4d",c);
        }
        printf("\n");
    }
}

Sample Output:

Input number of rows: 5                                                                                       
             1                                                                                                
           1   1                                                                                              
         1   2   1                                                                                            
       1   3   3   1                                                                                          
     1   4   6   4   1
