The "Do While" loop in C is a control flow statement that executes a block of code at least once before checking a condition at the end of the loop, ensuring that the code runs regardless of the condition initially. It follows the syntax: `do { /* code to execute */ } while (condition);`, where the loop only continues if the condition is true. This structure is particularly useful when you want to execute the loop's body at least once, like reading user input and processing it.

Do While Loop is a fundamental concept in programming, particularly in the C language. It is used to execute a block of code repeatedly, but unlike other loops, it checks the given condition after the loop body has executed. This ensures that the loop body executes at least once, regardless of the condition.
The basic syntax for a Do While Loop in C is as follows:

Mobile App do { // Statements to be executed} while (condition);Let's break it down:The syntax for a Do While Loop in C is quite straightforward. It is particularly useful when you need to ensure that a block of code is executed at least once.
In C programming, the Do While Loop is defined using the following syntax:
do { // Statements to be executed} while (condition);This structure allows the loop body to execute before the condition is tested.A Do While Loop in C is a control flow statement used to execute a block of code at least once, continuing execution as long as the specified condition evaluates to true.
Example: Calculate the sum of numbers from 1 to 5 using a Do While Loop:
int sum = 0;int i = 1;do { sum += i; i++;} while (i <= 5);This example demonstrates how the loop iterates, incrementing and adding values until the condition is no longer met. Remember, the loop will always execute at least once, which makes it an excellent choice for situations where the condition might initially be false.
In comparison to other loop structures like for and while loops, the Do While Loop is unique in its ability to guarantee execution. This feature can be particularly advantageous with user input scenarios or when dealing with operations that inherently need an initial execution before proceeding with condition checks. For instance, in user authentication processes, you might want to ensure that the login attempt is processed at least once regardless of the conditions.
In C programming, the Do While Loop is a tool that helps execute code multiple times based on a condition. This structure is unique because it evaluates the condition after executing the loop body.
Here's a look at the core parts of a Do While Loop in C:
do { // Statements to execute} while (condition);A Do While Loop is a loop structure in C that executes a block of code at least once and then repeatedly executes the block as long as a specified condition is true.
Example: Calculate the factorial of a number using a Do While Loop:
int number = 5;int factorial = 1;int i = 1;do { factorial *= i; i++;} while (i <= number);This example illustrates the loop iterating to calculate the factorial, incrementing and multiplying values until the condition is met. Use a Do While Loop when it is essential for the code block to run at least once irrespective of the condition.
The Do While Loop is particularly useful in scenarios where you have to execute a sequence of actions before determining if further iteration is necessary. Consider cases like menu-driven applications:
Understanding the Do While Loop through examples can help solidify your grasp of this programming concept. Below are practical examples that demonstrate how this loop operates in the C language.
do { // Statements } while (condition); - Code inside the block executes before the condition is evaluated.Sign up for free to gain access to all our flashcards.
