What are functions and pointers in C++?

What are functions in C++?

Functions in C++ are blocks of code that perform a specific task and can be reused throughout the program.

Can you explain what pointers are?

Pointers are variables that store the memory address of another variable, allowing for dynamic memory management.

How do functions and pointers work together?

Functions can take pointers as parameters, enabling them to modify the original variable's value directly.

Can you give me an example of using a pointer in a function?

Sure! Here's a simple example:

void increment(int* ptr) {
    (*ptr)++;
}

int main() {
    int num = 5;
    increment(&num);
    // num is now 6
}
