Thread: Help with beginning program

In my book is says to write a program in its little review section. (I only want to make the first pattern, so that's all I'm gonna type out. ) I can't figure out how to print a character in increasing number for the life of me. I can do it easily with integers, but I have no idea how to do it with non integers. It's driving me nuts.

Here are it's instructions

Write a program that prints the following patters separately on below the other. Use "for" loops to generate the pattersn. All asterisks(*) should be printed by a single statemnt of the form "cout << '*';" (this causes the asterisks to print side by side) Hint: The last two patterns require theat each line begin with an appropriate number of blanks.

*
**
***
****
*****
******
*******
********
*********
**********

Here's a hint : You can print as many asterisks as you want, they all end up on the same line* - that is, untill you print a newline character.


*Technically anyway, the console does wrapping automagically.

nevermind guys. I was able to figure it out.

wow..i actually did it.I hope no one minds me posting my code here

Code:

#include <iostream>
void star(int x);
int main()
{
int x;
for (x=0;x<10;x++)
{
star(x);
std::cout<<"\n";
}
return 0;
}
void star(int x)
{
for (int y=0;y<=x;++y)
{
std::cout<<"*";
}
}

>wow..i actually did it.
Congratulations. That's a good solution too. Well done, and I hope you had enough fun doing it to keep going with C++.

>I hope no one minds me posting my code here
No one ever minds seeing code. In fact, that's a good way to get critiques from very knowledgeable programmers. You can show off , help people who search the boards with a similar problem, and help yourself improve by putting your code out to be checked by many eyes. Provided you have a strong constitution (some people can be vicious in nitpicking code), you can learn a great deal.

Apparantly, that only applies to CODE tagged code

hey guys i have been an avid reader of the forums here but havnt gotten a membership until now becuase i had this problem that has puzzled me. i was working on modifying this program to go in a decreasing fashion. i couldnt do it hardcoded or with user defined variables. i dont know why it wasnt working probibly some really big flaw that i missed as a newb.

Code:

#include <iostream>
#include <stdlib.h>


using namespace std;


int star(int x)
{
    for (int y=1;y<=x;++x)
    {
    cout<<"*";}
    }
int negastar(int x)
{
    for (int y=1;x>y;x-1)
  {
     cout<<"*";
  }    
}


int main()
{
int x;
for (x=0;x<10;x++)
    {
    star(x);
    cout<<"\n";
    }
while(x>1)
{
    negastar(x);
    cout<<"\n";
}
system("pause");
return 0;
}

im using dev-c++ from bloodshed with the latest updates and everything and i dont think its a software problem. thanks for all the help in advance
