I am attempting to create a program to take in file input the user specifies, then count the frequency of each letter, then produces individual text files for each paragraph that it counts.
This program compiles perfectly on Microsoft Visual Studio Enterprise 2017. However, when I attempt to run it on my schools computer (running GCC 4.8.5), the program fails and throws errors such as:
"no matching function for call to ‘std::basic_ifstreamr>::open(std::string&, const openmode&)’"
Any thoughts or suggestions?
