This tutorial will teach you everything you need to know about generic looping techniques in C++. The C++ programming language provides loops in three distinct ways: for loop, while loop, and do-while loop. You will also see how the infinite loop works in C++.
In programming, there are times when an operation must be performed more than once or n times. When we need to execute a set of statements repeatedly, we use loops.
There may be times when you need to execute a block of code several times. In general, statements are executed in the following order: the first statement in a function is executed first, then the second, and so on. Different control structures are offered by programming languages, enabling more complex execution paths.
A loop statement allows us to execute a statement or group of statements multiple times, and the general form of a loop statement in most programming languages is as follows:
In C++, loops are classified mainly into two types:
So in order to handle looping requirements, the C++ programming language provides the following types of loops as mentioned above.
|Repeats a statement or group of statements while a given condition is true. It tests the condition before executing the loop body.
|Execute a sequence of statements multiple times and abbreviates the code that manages the loop variable.
|Like a ‘while’ statement, except that it tests the condition at the end of the loop body.
|You can use one or more loop inside any another ‘while’, ‘for’ or ‘do..while’ loop.
