C Program to Print Pascal Triangle Source Code

/* C Program to print pascal traiangle - PascalTriangle.C */

#include <stdio.h>
int main()
{
//variable declaration
 int rows, coef = 1, space, i, j;

//asking user to enter number of rows and reading
printf("Enter number of rows: ");
 scanf("%d",&rows);

//logic for printing pascal triangle
for(i=0; i<rows; i++)
 {
 for(space=1; space <= rows-i; space++)
 printf(" ");

for(j=0; j <= i; j++)
 {
 if (j==0 || i==0)
 coef = 1;
 else
 coef = coef*(i-j+1)/j;

printf("%4d", coef);
 }
 printf("\n");
 }

return 0;
}
