    How would you open a text file and then see how many instances of a number there are

    I have a file like this

2

    Code (markup):
    Where I want to use out how many times the number 1 and 2 occurs.

    Read each line. Increment a counter each time you read a line that's "1".

    Delete all 2s, all LFs, and all CRs. Then you will have a line like "11111111". Length of line is number or 1s in the line.
