When Compiling c++ program in VSC I get this error.

./a.out : The term './a.out' is not recognized as the name of a cmdlet, function, script file, or operable program.       
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

Java Programs are running fine, but c++ is giving this error. Solve it please!
