Question

What code structure will run command only if a specific condition has been met?

a) do-while loop
b) switch statement
c) if statement
d) for loop

Answer 1

The correct code structure for executing a command if a specific condition is met is the if statement (c). It evaluates a given condition and executes the associated code only if that condition is true.

Step-by-step explanation:

Code Structure for Conditional Command Execution

The code structure that will run a command only if a specific condition has been met is the c) if statement. An if statement evaluates a condition and executes the subsequent block of code only if that condition is true. For example, in many programming languages, you would use the if statement as follows:

if (condition) {
// Command to execute if the condition is true
}

This structure is fundamental to programming and is used to control the flow of a program based on certain criteria. Unlike a do-while loop or a for loop, which are used for iteration, the if statement is specifically designed for decision-making processes. The switch statement, on the other hand, offers a different kind of conditional execution that allows a variable to be tested against a series of values. However, for a single, specific condition, the if statement is the correct choice.
