CPP comments are used to give a brief description about any specific line of code or about a module in the code to make the code more user-friendly.
CPP Comments can be of two types:
- Single line Comments
- Multi line Comments
Single Line Comments:
Single line comments can be used for commenting a line of the code or to write a single line description about the code. The lines starting with // is considered as single line comment.
Multi Line Comments:
Multi line comments can be used for commenting a part of the code or to write a multiple lines description about the code. The lines enclosed between /* */ are considered as multi line comments.
Example:
#include <iostream.h> using namespace std; int main() { int n; cout << "Enter a number: "; cin >> n; /* if the number is less than 5, the break will directly go to less label. */ if (n < 5) goto less; // otherwise print the number. else cout << n; less: cout << "less than 5"; return 0; } |
Output:
Enter a number: 4 less than 5 |
