How can I count frequencies of characters in string!!!!??

Question

I am reading from an input file and want to read all letters and symbols. I am looking to create something bigger from this like encode it eventually - but I cannot seem to move from this block of trying to read in characters and use its frequency in a vector which I would sport in a heap. For context, how can I get something like this:
"I am soo stuck." --> i:1 a:1 m:1 s:2 o:2 t: 1 u:1 c: 1 k:1 :3 (represents spacing) -- and how can i order them from least to greatest frequencies?

please help!

Did you notice something strange in the forum?

I see another post exactly like this one, just below it in the post list, it has a blank profile picture and empty user name. But if I enter the post and refresh it by sliding down, the user name becomes this OP's name, and the profile picture also changes accordingly.

Guessing that this must be in C++ from the mention of map, heap, and vector in the tags. Serety this article might address for you how to sort the frequencies in a map:
