What are void functions in C++?
Void functions in C++ are functions that do not return a value. They are declared using the keyword 'void'.
Can you give me an example of a void function?
Sure! Here's a simple example:
void greet() {
std::cout << "Hello, World!";
}
This function prints a greeting but does not return any value.
How do I call a void function?
You can call a void function just like any other function. For example:
greet();
Are there any limitations to using void functions?
Yes, since void functions do not return a value, you cannot use them in expressions or assign their result to a variable.
