Solution

Control flow in C programming refers to the order in which the instructions, statements or function calls of an imperative program are executed or evaluated. The control flow of a C program is determined by decision making statements (such as if, switch), loops (such as for, while, do-while) and jumps (such as break, continue, goto).

Here's a step-by-step explanation:

  1. Decision Making Statements: These are used when we want to execute a certain block of code based on some condition. For example, the 'if' statement. If the condition is true, the block of code inside the 'if' statement is executed. If the condition is false, it's skipped.

  2. Loops: These are used when we want to execute a block of code multiple times. For example, the 'for' loop. We specify the initial condition, the final condition, and the increment/decrement. The block of code inside the 'for' loop is executed until the final condition is met.

  3. Jumps: These are used to jump to a certain point in the program. For example, the 'goto' statement. We specify a label and when the 'goto' statement is encountered, the control jumps to the specified label.

In summary, control flow is a fundamental concept in C programming that allows us to have a fine-grained control over the execution order of the program's code.
