Can the main() function in C programming call itself, thereby making it recursive?

The main function in C programming can indeed call itself, which allows for recursion. This means that the main function can be defined in such a way that it executes a set of instructions and, at some point, invokes another instance of itself. This is contrary to a common misconception that the main function should not be recursive.

The recursive call can be useful in certain applications, though it's important to manage the recursion properly to avoid indefinite loops or stack overflow errors. Just like with any recursive function, there must be a base case that eventually terminates the recursion to prevent infinite execution.

Although there might be restrictions or practical implications associated with recursion in main (such as typical conventions or behavior in specific compilers), from a technical standpoint, C allows the possibility of recursion within the main function. Therefore, the ability for main to call itself is valid, affirming the truthfulness of the assertion.
