Question

im looking for a way to open a text file and find a certain string and then get the line it is on, then get the contents of that line. I can’t find any help for this. Also i need to use C++ and preinstalled libs … etc. anything that wont work on a mac or isn’t preinstalled with c++…. I may be able to use small other libs…

Answer 1

open a filestream

while filestream is NOT at End Of File
    get a line of the file into a temp string
    search the temp string for the keyword
    if the keyword is in it
        thats your line, exit the loop
    else keep looping

hopefully that’s a big enough hint for you.
