In this C++ tutorial, you will learn how to iterate over a vector using For loop statement, with example program.

C++ Iterate over Elements of Vector using For Loop

To iterate over the elements of a vector using For loop, start at zero index and increment the index by one during each iteration. During the iteration, access the element using index.

Example

In the following C++ program, we define a vector, and iterate over its elements using For loop.

main.cpp

</>
Copy
#include <iostream>
#include <vector>
using namespace std;

int main() {
    vector<string> arr{ "apple", "banana", "cherry" };
    for ( int index = 0; index < arr.size(); index++ ) {
        string element = arr.at(index);
        cout << element << endl;
    }
}

Output

apple
banana
cherry
