What function provides the entry point into the application?

1. main()

2. primeCheck()

3. assertFalse()

4. checkArgs()

The correct answer is: main()

The function that serves as the entry point into a program is typically named 'main()'. In many programming languages, such as C, C++, and Java, the execution of the program begins in the 'main()' function. This function acts as the starting point where the program control is transferred when the program is executed. Its signature is often predefined by the language's specification, meaning that the language expects to find this function to initiate the program's workflow. The other functions mentioned serve different purposes within a program. 'primeCheck()' is likely a specific function designed to determine if a number is prime, while 'assertFalse()' is commonly associated with testing frameworks to assert that a condition is false during unit testing. 'checkArgs()' could be a utility function to validate command-line arguments but does not indicate where the program execution starts. Thus, the main function is ultimately what allows the program to be run and provides a framework for the subsequent functionality defined in the program.
