c++ compile

// Step 1: Write the C++ code in a file, for example, "example.cpp".
#include <iostream>

int main() {
    // Step 2: Define the main function where the program execution begins.
    std::cout << "Hello, World!" << std::endl;

    // Step 3: Return 0 to indicate successful execution to the operating system.
    return 0;
}

# Step 4: Open a terminal and navigate to the directory containing the C++ file.
# Step 5: Compile the C++ code using a C++ compiler, such as g++.
g++ example.cpp -o example

# Step 6: Run the compiled executable.
./example

Explanation: 1. The C++ code is written in a file named "example.cpp". It includes the necessary header file <iostream> for input and output operations.

  1. The main function is defined, serving as the entry point for the program.

  2. Inside the main function, a simple "Hello, World!" message is printed to the standard output using std::cout.

  3. The program returns 0 to indicate successful execution to the operating system.

  4. In the terminal, navigate to the directory containing the C++ file.

  5. Use the g++ compiler to compile the C++ code. The -o option specifies the name of the output executable, which is set to "example" in this case.

  6. After successful compilation, run the generated executable by typing ./example in the terminal.

  7. The "Hello, World!" message should be displayed as the output of the program.
