c program to print pascal triangle:
#include <stdio.h>
long fact(int);
int main()
{
int n, i, j;
printf("Please enter number of rows you would like to see in pascal triangle\n");
scanf("%d",&n);
printf("Pascal Triangle pattern:\n");
for ( i = 0 ; i < n ; i++ )
{
for ( j = 0 ; j <= ( n - i - 2 ) ; j++ )
printf(" ");
for( j = 0 ; j <= i ; j++ )
printf("%ld ",fact(i)/(fact(j)*fact(i-j)));
printf("\n");
}
return 0;
}
long fact(int n)
{
int c;
long result = 1;
for( c = 1 ; c <= n ; c++ )
{
result = result*c;
}
return ( result );
}
Output:
Please enter number of rows you would like to see in pascal triangle
6
Pascal Triangle pattern:
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
1 5 10 10 5 1
