i have made a small encyption program nothing fancy really. it turns the letters into 6-9 digit long number seperating each with a \n
i now need to read in each numbers so i can reverse the calculation for the decyrpt but cant seem to work out how to read the number from the text file "output.txt" and store ir as an int so i can preform calculation on it.
i need to do this in c NOT C++ AND NOT C#
if anyone can help id really appriciate it. i tryed using fgetc and concatonating the chars togethers and atio them but coudnt get it to work.
