General Structure of a C++ Program

1. General Syntax:-

#include <iostream>

using namespace std;

int main() {

    // Statements

    return 0;

}

1. Example of a Basic C++ Program

#include <iostream>

using namespace std;

int main() {

    cout << “Welcome to C++ Programming!” << endl;

    return 0; }

Output:-

Welcome to C++ Programming!

1. Explanation of the Example

1. The #include <iostream> directive tells the compiler to include the standard input-output stream library which is needed for using cout and cin.
2. The using namespace std; statement allows direct access to all entities in the standard namespace without prefixing them with std::.
3. The main() function is the entry point of a C++ program. Execution starts from this function.
4. The cout statement is used to display output to the screen. The insertion operator (<<) sends the data to the output stream.
5. The return 0; statement indicates that the program has executed successfully.
