This is not an error  it is a warning from your Microsoft compiler   Select your project and click  Properties  in the context menu   In the dialog  chose Configuration Properties -  C C   -  Preprocessor  In the field PreprocessorDefinitions add   CRT SECURE NO WARNINGS to turn those warnings off

This is a warning for usual  You can either disable it by   pragma warning disable 4996    or simply use fopen s like Microsoft has intended   But be sure to use the pragma before other headers
