counting groups of strings or int

[greezmky]

A brief explanation of what I am trying to do then my code thus far, and please note that I am a self taught beginner at this point.

I modified a bitmap image to 6 colors and 279 x 184 pixels, it is 24bit. This is a template for a blanket that my Mom is crocheting for a Christmass present. Each pixel represents a stitch (or whatever they call it). She is crocheting in a column fashion, so at this point I have to call out the number of colors for each stitch i.e. pixel. It is annoying using gimp and the measuring tool.

So I found out how to use EasyBMP. Manually was way to hard. I wrote some code and I'm half way there. I am using EasyBMP because I am programming on a Mac in C++.

I converted the int returned decimals for R, G, B to a string so that I could compair them to my 6 specific values. I couldn't figure out how to do it with int. And EasyBMP documentation is limited.

The Problem
Now I am able to print row 0-178 out as a sequential data 12345... or color red red red black black....

However I need to count like/same colors, display the sum of same colors, and reset the counter until that color comes up again. I thought an if or if else would do it but not quite. It may be my code structure that is causing an issue?

Here is my code, I am a beginner so criticizes on my lack of knowledge so that I may learn properly.
