The foreach loop in C or more specifically, range-based for loop was introduced with the C11.This type of for loop structure eases the traversal over an iterable data set. It does this by eliminating the initialization process and traversing over each and every element rather than an iterator. C Nested Loop - Writing a loop inside another loop is known as nested loop. Maximum level of nesting allowed in C is 256. We can write while, do.while, for and range based for loop in a nested loop. Difference between for loop and foreach loop: for loop executes a statement or a block of statement until the given condition is false. Whereas foreach loop executes a statement or a block of statements for each element present in the array and there is no need to define the minimum or maximum limit. For example, if a = 2 and x = 4, the values will be 2, 4, 16, and 256, which are way bigger than you want them to be. To fix this, try changing your loop so that you have a secondary variable, initially set to 1, that you keep multiplying by a. That way, you don't change what value you're multiplying by on each iteration.

A for loop is a repetition control structure that allows you to efficiently write a loop that needs to execute a specific number of times.

Syntax

The syntax of a for loop in C++ is −

Here is the flow of control in a for loop −

• The init step is executed first, and only once. This step allows you to declare and initialize any loop control variables. You are not required to put a statement here, as long as a semicolon appears.

• Next, the condition is evaluated. If it is true, the body of the loop is executed. If it is false, the body of the loop does not execute and flow of control jumps to the next statement just after the for loop.

• After the body of the for loop executes, the flow of control jumps back up to the increment statement. This statement can be left blank, as long as a semicolon appears after the condition.

• The condition is now evaluated again. If it is true, the loop executes and the process repeats itself (body of loop, then increment step, and then again condition). After the condition becomes false, the for loop terminates.
