  • C Program to Print Pascal Triangle using Recursion

C Program to Print Pascal Triangle using For Loop

#include <stdio.h>

long Factorial(int);

int main()
{
   int i, Number, j;

   printf("Enter number of rows : ");
   scanf("%d", &Number);

   for (i = 0; i < Number; i++)
   {
      for (j = 0; j <= (Number - i - 2); j++)
      {
      	printf(" ");
	  }

      for (j = 0; j <= i; j++)
      {
      	printf("%ld ", Factorial(i) / (Factorial(j) * Factorial(i-j)));
	  }

      printf("\n");
   }

   return 0;
}

long Factorial(int Number)
{
   int i;
   long Fact = 1;

   for (i = 1; i <= Number; i++)
         Fact = Fact * i;

   return Fact;
}

The output of the above c program; is as follows:

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

C Program to Print Pascal Triangle using Recursion

#include <stdio.h>
long Factorial(int Number)
{
  if (Number == 0 || Number == 1)
    return 1;
  else
    return Number * Factorial (Number -1);
}

int main()
{
   int i, Number, j, Fact;
   printf("Enter number of rows : ");
   scanf("%d", &Number);
   for (i = 0; i < Number; i++)
   {
      for (j = 0; j <= (Number - i - 2); j++)
      {
      	printf(" ");
      }
      for (j = 0; j <= i; j++)
      {
      	Fact = Factorial(i) / (Factorial(j) * Factorial(i-j));
	printf("%ld ", Fact);
      }
      printf("\n");
   }
   return 0;
}

The output of the above c program; is as follows:

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