We're starting out by printing the most famous computing phrase of all time! In the editor below, use either printf or cout to print the string Hello, World! to stdout.

The more popular command form is cout. It has the following basic form:

cout<<value_to_print<<value_to_print;

Any number of values can be printed using one command as shown.

The printf command comes from C language. It accepts an optional format specification and a list of variables. Two examples for printing a string are:

printf("%s", string); printf(string);

Note that neither method adds a newline. It only prints what you tell it to.

Output Format

#include <iostream>
#include <cstdio>
using namespace std;

int main() {
    cout <<"Hello, World!";
    return 0;
}

Steps used in solving the problem -

Then, we declared the standard namespace in the program. This means we don't need to prefix any standard functions or objects with the std:: prefix.
Then, we created a main function and used cout to print "Hello, World!" .
