I would like to know why, when you run the following code, there is a little window in which it says:
can not start the program
followed by:
can not find the specified file
It also gives these errors:
'fopen': This function or variable may be unsafe. Consider using fopen_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS.
'fprintf': unknown type field character '' in format specifier
The purpose of the program:
Could you please help me, is there an error in the code?
