An example of an AI chatbot conversation about passing parameters in C++.
How do I pass parameters in C++?
In C++, you can pass parameters to functions by value, by reference, or by pointer. Which method would you like to know more about?
What's the difference between passing by value and passing by reference?
Passing by value means a copy of the variable is made, while passing by reference means the function works with the original variable. This affects memory usage and performance.
Can you give me an example of passing by reference?
Sure! Here's a simple example:
void increment(int &value) {
value++;
}
int main() {
int num = 5;
increment(num);
// num is now 6
}
