}

im using this same method for all other file related functions in the program
the code works well in online compilers, but i need it to work on code blocks specifically
the file itself is in the c directory, i’ve tried changing it from read only mode, and it still does not work
there is another question that is similar to mine, however, the answers on it do not solve my issue
