This is the basic program, now I'm looking at the problems with printing the histogram vertically.
More planning, obviously. Have to know in advance how high the highest bar will be, and how wide the graph will be.
Then I need to figure a way to lock the vertical bars into the correct horizontal column...
Anyway, here's the horizontal version.
I spent some time playing around with labels, but I couldn't get the "%" sign to print! Printf uses it for the signal, and it was really annoying.

Pludi, I've been thinking about this statement since I read it.
I'm starting to see what you mean, but I don't know.
Do you mean that knowing the principle of "For (x = 0, x<=y, x++)" is more important than knowing how to write it?
I think I see that. If you know what you want to do, then you only have to find out how to write it, rather than figuring out how to do it.

The... (6 Replies)

I want to insert "Text" in each file as a place where I mentioned below "Insert Text Here". These files are something like news of newspaper. Generally, newspaper headlines contain one or two lines.
