1. Syntax The for-each loop does not use the index variable. It uses a variable of the base type of the Collection or the array we will iterate, followed by a colon and finally the array/collection itself. In the following code, thearraycontains the elements of typeT. Theitemis the v...
Thefor-loopstatement in Java provides a compact way to iterate over the arrays or collection types using a counter variable that is incremented or decremented after each iteration. Programmers often refer to it as thetraditional “for loop”because of the way it repeatedly loops until a particular...

When: You have a foreach loop that uses an IEnumerable, and you want that loop to read as a LINQ query. Why: You prefer to use LINQ syntax rather than a foreach loop. LINQ makes a query into a first-class language construct in C#. LINQ can reduce the amount of code in a file,...
Now that we have a clear understanding of the syntax and functionality of the for loop in C++, let's look at a few code examples. Example 1: To Find The Factorial Of A Number Using For Loop In C++ In this example, we’ll use a C++ for loop to calculate the factorial of a given...
