Comments:

Comments in programming languages are those statements which are not needed to compile by the compiler. C++ supports both single line and multiple line comments. Single line comment is also known as double slash comment (i.e. //). It this comment is to be used for multiple line, we should use // for each line separately.

e.g.

   //This is single line

  // comment used for multiple line

Again, it supports C style comment (i.e. /*    */). This type of comment is generally used for multiple lines. The lines between /* and */ are not compiled.
