long factorial(int);
int main()
{
int i, n, c;
printf(“Enter the number of rows you wish to see in pascal triangle\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(i-c)));
printf(“\n”);
}
return 0;
}

long factorial(int n)
{
int c;
long result = 1;
for( c = 1 ; c <= n ; c++ )
result = result*c;
return ( result );
}

output:
