Here is an example of the structure of a C++ program:
#include <iostream>
using namespace std;
int main()
{
cout << "Hello, World!" << endl;
return 0;
}
In this example, the program includes the iostream
header file, which provides access to the cout
and endl
functions. The using namespace std
directive allows the program to use the cout
and endl
functions without specifying their namespace.
The main
function is the entry point of the program. It is where the program execution begins and ends. In this example, the main
function uses the cout
function to print the string “Hello, World!” to the standard output, followed by a newline character using the endl
function.
Finally, the return 0
statement indicates that the program has finished executing successfully.
Overall, this is a simple example of a C++ program that demonstrates the basic structure of a C++ program. It includes a header file, a namespace directive, a main function, and a return statement.
