Loop | MCQs

Explanation

The do-while loop is useful when the loop must run at least once, even if the condition is false initially.

It's suitable when the number of iterations is not known in advance and depends on runtime conditions.

Explanation

The for loop is ideal when the number of iterations is known beforehand.

It allows initializing, testing, and updating the loop variable in a single line.

Explanation

The continue statement skips the remaining code inside the loop for the current iteration.

It then shifts control back to the beginning of the loop for the next iteration.

Explanation

The break statement, when used inside a loop, immediately exits the loop and transfers control to the statement following the loop.

It does not terminate the entire program, only the current loop.

Explanation

In a do-while loop, the body executes first, and the condition is checked afterward, ensuring it runs at least once.

This differs from for and while loops, which check the condition before executing.

Explanation

Nested loops are loops placed inside another loop.

It allowing complex iteration through multi-dimensional data structures.

They are commonly used for tasks like processing matrices or multi-level data.

Explanation

do-until is not a valid loop structure in C programming.

C provides for, while, and do-while loops for iteration.

Explanation

Iteration refers to the process of repeatedly executing a set of instructions or statements in a loop.

It is used to perform the same operation multiple times, such as in loops like for, while, and do-while.

Additional information::

Recursion involves a function calling itself,

 Conditional statements and function calls serve different purposes in programming.

Explanation

• In C, the For loop is commonly used to iterate through an array because it allows for easy initialization, condition checking, and incrementing/decrementing of the loop counter.
• The syntax of a For loop is designed to handle array indexing and iteration naturally.

Explanation

A nested loop has one loop inside of another.

These are typically used for working with two dimensions such as printing stars in rows and columns as shown below.

When a loop is nested inside another loop, the inner loop runs many times inside the outer loop.
