Description: The ‘Do-While’ statement in C++ is a control flow structure that allows a block of code to be executed at least once and then repeated while a specified condition is true. This feature is particularly useful in situations where the code needs to run at least once before evaluating the condition. The basic syntax of a ‘Do-While’ loop includes the keyword ‘do’, followed by a block of code enclosed in braces, and then the keyword ‘while’ followed by the condition in parentheses. This structure ensures that the code block is executed first, which distinguishes it from other loops like ‘While’, which evaluates the condition before execution. The flexibility of ‘Do-While’ allows programmers to handle situations where initial execution is necessary, such as in user input scenarios, where a message should be displayed at least once before prompting for a response. Additionally, its use can contribute to code clarity, as it allows for more direct expression of intentions compared to other loops. In summary, ‘Do-While’ is a powerful tool in C++ that facilitates the creation of condition-controlled loops, ensuring that the code runs at least once.
