Comments are hints that a programmer add to explain code and make it more understandable.
There are two types of comments in C++ language:
1. Single Line Comments, &
2. Multi Line Comments.
Single line Comments :
Single-line comments Start with two forward slashes(//).
Any text are write after the forward slashes(//) then the line is ignored by java(will not be executed).
Example:
//Program to add two numbers.
class Demo {
public static void main(String[] args) {
//Declaring and initilizing variables.
int num1 = 28;
int num2 = 32;
int sum = num1+num2; //adding both numbers in sum variable.
//print the sum of num1 and num2.
System.out.print("Sum: "+sum);
}Multi-line comments:
Multi-line comments start with /* and ends with */.
Any text are write between /* and */ will be ignored by java .
Example:
/*Progrm in java to
add two numbers.*/
class Demo {
public static void main(String[] args) {
//Declaring and initilizing variables.
int num1 = 28;
int num2 = 32;
int sum = num1+num2;
//print the sum of num1 and num2.
System.out.print("Sum: "+sum);
}
