How to Iterate Over an Array in C++ ?

Answer

To iterate over an array in C++, you can use a for loop or range-based iteration.

✐ Examples

1 Iterate Over Integer Array with for Loop

In this example,

We create an integer array named numbers with some values.
We use a for loop to iterate over each element of the array and print the elements.

C++ Program

#include <iostream>
using namespace std;
int main() {
    int numbers[] = {1, 2, 3, 4, 5};
    for (int i = 0; i < sizeof(numbers) / sizeof(numbers[0]); i++) {
        cout << numbers[i] << endl;
    }
    return 0;
}

Output

2 Iterate Over String Array with Range-Based Loop

In this example,

We create a string array named fruits with some values.
We use a range-based loop to iterate over each element of the array and print the elements.

C++ Program

#include <iostream>
#include <string>
using namespace std;
int main() {
    string fruits[] = {"apple", "banana", "cherry"};
    for (const auto &fruit : fruits) {
        cout << fruit << endl;
    }
    return 0;
}

Output

apple
banana
cherry
