C++ For Each Element in Vector

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

C++ For Each Element in Vector

To execute a set of statements for each element in the vector, we can use C++ For-Each statement.

Example

In the following C++ program, we define a vector, and execute a set of statements for each element in this vector.

main.cpp

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

int main() {
    vector<string> arr{ "apple", "banana", "cherry" };
    for ( string x: arr ) {
        cout << "Eat " << x << "." << endl;
    }
}

Output

Eat apple.
Eat banana.
Eat cherry.

Conclusion

In this C++ Tutorial, we learned how to execute a set of statements for each element in a vector using For-Each statement.
