How do I iterate through an array in C++?

How do I iterate through an array in C++?

You can use a for loop to iterate through an array in C++. For example:

int arr[] = {1, 2, 3, 4, 5};
for(int i = 0; i < 5; i++) {
    std::cout << arr[i] << " ";
}

Can you explain how the for loop works in this context?

Sure! The for loop initializes an index variable i, checks if it's less than the size of the array, and increments it after each iteration.

What if I want to use a while loop instead?

You can use a while loop like this:

int i = 0;
while(i < 5) {
    std::cout << arr[i] << " ";
    i++;
}

Are there any other methods to iterate through an array?

Yes, you can also use range-based for loops in C++11 and later:

for(auto& element : arr) {
    std::cout << element << " ";
}
