In C++ what is comment in c++ language.

                                                                                                                    COMMENT

 this is comment ,   





 

Comments are used by the programmer to make the code understandable so that is can be improvised later and to make it more readable. It can also be used to prevent execution when testing alternative code.

 

There are two ways to write Comments: singled-lined or multi-lined.

 

Single line comments

 

Single-line comments are initiated with two forward slashes (//). This comments the entire line after the two slashes.

 

Example:-





#include <iostream>

using namespace std;

int main() {

    // this is a comment won't be executed

    cout <<"this word will print";

    return 0;

}






 

Multi Line comments

 

Multi-line comments start with /* and ends with */

 

The text in between both of these will not be executed by the compiler. Hence comments can we written in multiple lines

 

Example:



#include <iostream>

using namespace std;

int main() {

    /* this is a multi line comment 

    which is not executed */

    cout <<"this word will print";

    return 0;

}







please try yourself this code so you can learn better way ,

thanks for reading this blog for comment .

SYNTAX IN C++     The following code is written in C++ We shall look at each element of the following code in detail to understand  the syntax of C++ EXAMPLE -  #include <iostream> using namespace std; int main() { cout << "Hello World." ; return 0 ; } HERE we explain it - #include <iostream>:  This is a header file library. <iostream> stands for standard input-output stream. It allows us to include objects such as cin and cout, cerr etc.   using namespace std:  Means that names for objects and variables can be used from the standard library. It is also used  as additional information to differentiate similar functions.    int main():  The function main is called just as in C. Any code inside its curly brackets {} will be executed.   cout:  is an object used to print a particular text after << in quotes. In our example it will output "Hello World". (for personal reference ...

DATA types in C++ languages .

                                                             Data types   We already introduced data types earlier in the variables section. Here is an example of a code with all the data types used for revision purpose. this is the data types -  Int - 4 bytes Float - 4 bytes Double - 8 bytes Char - 1 byte Bool – 1 byte #include <iostream> #include <string> using namespace std; int main () { // Creating variables int _Num = 5; // Integer float _Float = 5.99; // Floating point number double _Double = 9.98; // Floating point number char _Char= 'G'; // Character bool _Bool = true; // Boolean string _String = "Namaste"; // String // Print variable values cout << "int: " << _Num << "\n"; cout << "float: " << _Float << "\n"; cout << "dou...
