Question

Every \(\mathrm{C}++\) program must have a function named ___________.

Short answer

Answer: The entry point of every C++ program is the function named "main".

Step-by-step solution

Required Function Name

Every C++ program must have a function named "main". This function serves as the entry point of the program and marks the beginning of the program's execution.

The Main Function

The "main" function has a specific syntax and typically returns an integer to the operating system. Here's a simple example of the main function: ```cpp #include int main() { std::cout << "Hello, World!" << std::endl; return 0; } ``` In this example, the "main" function outputs "Hello, World!" to the console and returns 0 to the operating system, indicating a successful execution.
