What are conditional statements used for in C?

• A. To create multi-dimensional arrays
• B. To execute different blocks of code based on a condition
• C. To define functions within the program
• D. To allocate memory dynamically

Answer: (B)

Conditional statements in C are a fundamental construct that allows the program to execute different blocks of code based on whether a specified condition evaluates to true or false. These statements enable decision-making within a program, which can affect the flow of execution and determine which pieces of code should run in various scenarios. For instance, using an 'if' statement, you can check a condition, and if that condition is met (true), the code block associated with that 'if' runs. There is also the option to have 'else' to specify what should happen if the condition is not met (false). This mechanism is essential for tasks where the outcome depends on certain variable states or user inputs. In building applications where logic and responses to different scenarios are crucial, conditional statements become invaluable. They facilitate branching in the code, providing clarity and control over program flow. The other options do not pertain to the primary role of conditional statements. Creating multi-dimensional arrays involves defining data structures, defining functions pertains to modular programming, and dynamic memory allocation is concerned with managing memory during program execution. While all of these are critical aspects of programming in C, they do not directly relate to the decision-making capabilities provided by conditional statements.
