    Foreach loop is another loop which was introduced in C++ 11. The advantage of foreach loop over other loops is that, it can access elements of an array quickly without performing initialization, testing and increment/decrement, the code becomes more readable and there are less programming errors. The working of foreach loops is to do something for every element in an array rather than doing something n times.

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

     

    Program to demonstrate use of foreach loop is as follows:-

     

    // C++ program to demonstrate use of foreach
    
    #include <iostream>
    using namespace std;
     
    int main()
    {
      int arr[] = {50, 100, 90, 40};
     
      for (int i : arr) // Printing elements of an array using foreach loop
         cout << i << endl;
    }

    Output:

    50
    100
    90
    40
