Program that creates a parallelogram?

Hello,
I need help with figuring out how to create a program that creates a parallelogram made out of star characters (such as:'*'). This program is suppose to test my 'loop' skills.

The program is suppose to ask the user the height and width of the parallelogram and then display the parallelogram on the screen.

Right now, the program is displaying a square but NOT a parallelogram. I am having trouble with incorporating spaces into my loop.

For example: If I wanted to create a loop that simply prints out the letter: X with no spaces then creates a new line, then prints out X again with ONE space, then creates a new line, then prints out the letter X again with TWO spaces, then three spaces, then four, etc.....




Can someone please help?

Code:

---


int main () {

  int z, i, n, height, width;
  printf("Please enter the height of the parallelogram.\n");
      scanf("%d", &height);
  printf("Please enter the width of the parallelogram.\n");
      scanf("%d", &width);
  printf("\n\n\n"); 
     
  for(i=0; i < height; i++){
      for(n=1; n < width; n++)
        printf("*");
      printf("*");

  printf("\n");
 


 
}

Read up on the * modifier in fmtstr conversions.

Basically you can use something like printf("%*s",i,""); in your loop which will tell printf to print a blank string of width specified by i.

Oh okay!
Thanks for the info, I was trying sooo many different tricks but was unable to accomplish this. Thanks again!

I was trying to find information about fmtstr with out much luck:/

I tried including ***printf("%*s",i,"")**** in my code and it is still not working well:/

Code:

---

#include <stdio.h>


int main () {

  int i, n, height, width;
  char z;
  printf("Please enter the height of the parallelogram.\n");
      scanf("%d", &height);
  printf("Please enter the width of the parallelogram.\n");
      scanf("%d", &width);
  printf("\n\n\n"); 
     
  for(i=0; i < height; i++){
      for(n=1; n < width; n++)
        printf("*");
      printf("*");
  for(z=0; z < width; z++)
  printf("%*s",z,"");
  printf("\n");
 


 
}

           
 
 
  system("PAUSE");
  return 0;
 
}

You still only need 2 for loops, 1 for height 1 to actually print out the line of *. So if you have a for loop such as this:

Code:

---

for(i=0; i<height;i++) {
    printf("%*s",i,"");
    for(k=0;k<width;k++)
        putchar('*');
    putchar('\n');
}

---

The above is all you need to create a parallelogram. So the first printf statement prints the spaces, starting with 0 spaces, then 1 space, then 2 space BEFORE printing the line of *******s after which it prints another \n to start the next line...you have some excess printf calls in your version.

Thanks man! I finally got it~!

I appreciate it.

P.S
I used printf instead of putchar lol just out of curiousity, why putchar instead of printf? they both work in this case...
