Thread: Triangle

I am trying to generate a triangle using "height" as input. The triangle should look like this:

*
**
***
**
*

where the height is 3, for 3 asterisks. However, the input can be any integer value. You could have 5 for the height.
I have two functions to generate two parts of the triangle. One prints the top part (up to where the input number height...in this case, the 3 stars) and then the other function prints the bottom part. I'm having trouble with the bottom portion. Please help me. My source code is:

Code:

/*Project 52
Herbert Ortiz
Due: October 7. 2004
This program prompts user to input triangle base, and this info
will generate the shape of that triangle!*/

#include <stdio.h>
#include <conio.h>

void PrintLine(int linenum);
void PrintLine2(int area);

main()
{
 int area, area2;   //local variables declared
 int height;  //same here

 printf("Enter the height of the triangle: "); //
 scanf("%d", &height);

 for(area=0; area<=height; area++) //main for loop containing function call
 {
  PrintLine(area);  //function call
 }

 for(area2=height; area2>=0; area2--)
 {
  PrintLine2(area);
 }

 system("PAUSE");
}

void PrintLine(int linenum)  //function definition and header
{
 int i;  //local variable i will determine how the output is displayed

 for(i=0; i<linenum; i++)  //output for loop
 {
  printf("*");
 }

 printf("\n");
}

void PrintLine2(int area2)
{
 int j;

 for(j=area2; j>0; j--)
 {
  printf("*");
 }

 printf("\n");
}

The top portions is displayed fine, but the bottom part is messed up! What should my for loop be in order to fix this problem? Thanks!
