Foreach in C++ and Java

Foreach loop is used to access elements of an array quickly without performing initialization, testing and increment/decrement. The working of foreach loops is to do something for every element rather than doing something n times.

There is no foreach loop in C, but both C++ and Java have support for foreach type of loop. In C++, it was introduced in C++ 11 and Java in JDK 1.5.0

The keyword used for foreach loop is “for” in both C++ and Java.

C++ Program:

#include

using namespace std;

int main()

{

    int arr[] = { 10, 20, 30, 40 };

    for (int x : arr)

        cout << x << endl;

}

Java program

public class Main {

    public static void main(String[] args)

    {

        int arr[] = { 10, 20, 30, 40 };

        for (int x : arr)

            System.out.println(x);

    }

}

Advantages of Foreach loop:-
1) Makes code more readable.
2) Eliminates the possibility of programming errors.
