Mastering Loop Structures

A loop in programming is a control structure that allows a block of code to be repeated multiple times. Its purpose is to automate repetitive tasks and reduce code duplication.

A do.while loop is a post-test loop in which the condition is checked after the loop body is executed. It is used when you want the loop body to execute at least once, regardless of the initial condition.

The syntax of a do.while loop is as follows: do { // statements } while (condition);

A for loop is a pre-test loop that allows you to specify the initialization, condition, and increment/decrement in a single line. It is commonly used when the number of iterations is known.

The syntax of a for loop is as follows: for (init; condition; increment) { // statements }

A structure is a user-defined data type in C that allows you to combine different data types to store a particular type of record.

To define a structure in C, you use the struct keyword followed by the structure name and a block of statements enclosed in curly braces.

Structure members or elements are the variables or data types that make up a structure. They define the different attributes or properties of the structure.

There are two ways to declare variables of a structure in C: either by declaring them separately or by declaring them together with the structure definition.

Sure! For example, you can define a structure called 'Book' that holds the details of a book, including its name, price, and number of pages.
