T \(F \quad\) If other functions are defined before main, the program still starts executing at function main.

Short Answer

Expert verified

#answer_title# Program Execution starts at the main function #answer_content# The statement "If other functions are defined before main, the program still starts executing at function main" is True. In most programming languages, the main function serves as the entry point for program execution, regardless of the order of other function definitions. For instance, in C++, a program with a `print_message()` function defined before the `main` function will still start executing at the `main` function, with the `print_message()` function being called inside it.

Step by step solution

Assertion Explanation

In most programming languages, the main function serves as the entry point for the program execution. It doesn't matter if other functions are defined before or after the main function in the code. The program will always start execution from the main function.

T or F Explanation

The statement "If other functions are defined before main, the program still starts executing at function main" is True. As mentioned before, the main function is the entry point of a program and the order of other function definitions does not impact the execution starting point.

Example & Explanation

Let's consider a simple example to further illustrate this concept. Suppose we have the following C++ code: ``` #include void print_message() { std::cout << "Hello, World!" << std::endl; } int main() { print_message(); return 0; } ``` In this example, the `print_message` function is defined before the `main` function, but when the program is executed, it still starts at the `main` function. The `print_message()` function call from inside `main` directs the program to execute the `print_message` function and then return to the main function to continue its execution.
