Which looping control structure is suitable when the number of iterations is known beforehand?Question 4Answera.for loopb.while loopc.if-else statementd.switch statement

To determine which looping control structure is suitable when the number of iterations is known beforehand, we can analyze the options provided:

a. for loop: The for loop is commonly used when the number of iterations is known beforehand. It allows us to specify the initialization, condition, and increment/decrement in a single line, making it suitable for situations where we have a fixed number of iterations.

b. while loop: The while loop is generally used when the number of iterations is not known beforehand or when we want to repeat a block of code until a certain condition is met. It may not be the most suitable choice when the number of iterations is known beforehand.

c. if-else statement: The if-else statement is not a looping control structure. It is used for conditional execution of code based on a certain condition, but it does not provide a mechanism for repeating a block of code multiple times.

d. switch statement: The switch statement is also not a looping control structure. It is used for multi-way branching based on the value of a variable, but it does not provide a mechanism for repeating a block of code multiple times.

Based on the options provided, the most suitable looping control structure when the number of iterations is known beforehand is the for loop (option a).
