What are control structures in C?

Control structures in C are constructs that manage the flow of execution in a program. They determine the order in which statements or instructions are executed based on certain conditions or repetitions.

For example, decision-making statements like if, else, and switch allow a program to execute different branches of code based on specified conditions. Similarly, looping constructs such as for, while, and do-while enable a set of instructions to be executed repeatedly until a certain condition is met. This control over the execution flow is fundamental to creating dynamic and responsive programs, allowing software to make decisions, iterate through data, and react to user input or other conditions.

The aspect of controlling flow is what distinguishes control structures from the other provided choices. Data types, libraries, and functions might play important roles in programming, but they do not inherently manage the execution flow within a program, which is the primary purpose of control structures.
