Pascals Triangle

[nuimstudent]

Hey, I have to write a code which calculates pascals triangle using C. So Far I have the triangle with a right side allignment. As part of the assignment, we actually have to get the triangle to appear as a triangle.

I have the function recursively calling itself as below;

int pascal_num (int n, int r)
{
	int pnum;
	if (r == n || n == 1) {
		return 1; }
	pnum= (pascal_num (n, r-1) + pascal_num (n-1, r-1) );
return pnum;
}

Any suggestions on how I can do this?
I know I need ot use a for loop of some sort to print the spaces...

Did you ever do the one assignement where you needed to make a diamond or triangle pattern?

You could re-use that code.

Use the printf() function .
