Hi, I was wandering if anybody here could help me out with a programming assigment i have to do. I'm not asking for the total solution, I really want to learn this stuff, but i need some help with loops in C. We are supposed to make a program that will produce a parallelogram of "*" after a user has inputed the width and height. Here is a link to get the actual program description: http://www.geocities.com/alocaco2k1/program3.doc If somebody could just show me what a loop that does something like this I would be very greatful. Also we have another programming assigment due at a later date where we have to do some error cheking (which i'm pretty sure i can do) and take an integer and display its positive factors. Again, im kinda stuck with how to get and display the factors. again here is a link to download the specifics: http://www.geocities.com/alocaco2k1/program4.doc Much thanks to anyone who can help me out. ***Note: these programs will be compiled with gcc and run on a unix platform.

You'll get more help if you start and then show us what you've tried and then ask for help.

I agree with Don. Start on the assignments, show us what you have and where it fails. Then we will be more helpful when offering a range of solutions. Do not just give us your specs and expect us to write the code for you. Many months ago, I had a rant about homework, perhaps you can find it in the thread archives. IR

ok i have done what you guys suggested. Like I said before, im not asking for entire solutions, i didnt mean to come across that way. Anyway i have started the first program (Program3 - The Parallelogram) and I can't figure out what to do now. I have everything upto the output of the width of the parallelogram. Here is what i have so far: http://www.geocities.com/alocaco2k1/program3.c i tried making the variables integers, floats, doubles, etc. and i just left them as doubles. If anyone can help me out with this i would be greatly appriciative. Thanks.

This code will print the correct number of rows and columns, I will leave the spacing for you to figure out... its fairly trivial. Hopefully, my code below will clear up any problems or concerns you have. IR --- #include <stdio.h> int main(void) { double length, width, counter; //Gather Specifications printf("Enter the length of your parallelogram.\n"); scanf("%lf", &length); printf("Enter the width of your parallelogram.\n"); scanf("%lf", &width); //Varify length and width //printf("Length equals = %.0lf\n", length); //printf("Width equals = %.0lf\n", width); //Width of Parallelogram int rows = 0; int cols = 0; while (cols <= width - 1) { while (rows <= length - 1) { printf("*"); //return counter; rows++; } printf ("\n"); rows = 0; cols++; } system("pause"); return 0; }

Thanks a bunch IR, that seems to work very well. The only problem i am still having is getting the printed parallelogram to skew to the right one space for each row after the first. Do i have to right another loop just to do that or can i modify the current loops? Thanks.

Yup, I know that is a problem... didn't want to give you the entire assignment. You could do it either way... I would write a function called Spacer, pass it a integer value (of the current counter)... and return a string consisting of that many spaces to display it before each newline, but you can attack it which ever way you want.
