Simple Bar graph with larger numbers

[CDS]

Hello there,

I'm new to C++ and I want to do a simple graph with large numbers like 96.5 to 100.

I found this in a post on this forum but is closed to replies:

#include <iostream>
#include <string>

std::string InsertLine(int index)
{
	std::cout << "Enter the " << index + 1 << " items size in the bar graph: ";
	int itemSize;
	std::cin >> itemSize;

	std::string myString(itemSize, '*');

	return myString;

}

int main()
{
	std::cout << "How big would you like your bar graph: ";
	int graphSize;
	std::cin >> graphSize;

	std::string *graph = new std::string[graphSize];

	for(int i = 0; i < graphSize; i++)
	{
		graph[i] = InsertLine(i);
	}

	std::cout << "--------------------------------------------------" << std::endl;

	for(int i = 0; i < graphSize; i++)
	{
		std::cout << i+1 << ": " << graph[i] << std::endl;
	}

	std::cout << "--------------------------------------------------" << std::endl;

	delete[] graph;

	return 0;
}

I want to use large numbers like 96.5 and 100, but this causes the * to go to far off the screen and then continue on the next line.

How can I limit the output length of the '*' to display say about 50 of the * when I type in 100?

Any help would be greatly appreciated..... Is there a simple fix? :-(

Thank you in advance....

std::string myString(std::min( itemSize, 50 ), '*');

That is a really terribly written program.

It's not mine, I did not program it. I found it on this forum.

I just want to know how to cutdown the output of the * on the screen to half, to be able to fit on one line.
Anyone know how to do this?

Thank you.....

Thanks again, how do I now get it to work with float or double?

[jsmith]

Well, you can't output 0.3 asterisks, so you have to decide how you want to map the data.
How much does 1 asterisk represent?

[CDS]

Ahh thank you jsmith. Sorry, I didn't even think of that! One asterisk equals 1, so I need them to be equal to each 0.1 entered by user.

So how can I allow the user to input of say 95.1, 95.2, 95.3, 95.4, and so on. I need the asterisk to be displayed for each number to the right of the decimal one place. For example, starting from; 1.0, 1.1, 1.2, 1.3, 1.4, and 1.5 will look like this for output:

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

This is really getting me going and would love to figure this out, is it possible?
Thanks for all your help......

[jsmith]

Well, it's possible, sure, but then 1.1 == 2.0, 1.2 == 3.0, 1.3 == 4.0 (when viewing the graph).
