Question

What is a count-controlled loop?

Short answer

Answer: A count-controlled loop is a type of loop in programming that runs a specific number of times, based on a predetermined count. It uses a counter variable to keep track of how many times it has run and terminates the loop when the counter reaches a certain value. An example of a count-controlled loop is a "for" loop. Here's an example that prints numbers from 1 to 5: ``` for (int counter = 1; counter <= 5; counter++) { print(counter); } ``` In this example, the counter variable starts at 1, the loop control condition checks that the counter is less than or equal to 5, and the increment statement increases the counter by 1 in each iteration. When the counter becomes 6, the loop ends.

Step-by-step solution

Definition

A count-controlled loop is a type of loop in programming that runs a specific number of times, based on a predetermined count. It uses a counter variable to keep track of how many times it has run and terminates the loop when the counter reaches a certain value.

Counter variable

A counter variable is a variable used in a count-controlled loop to keep track of the number of times the loop runs. It is initialized with a starting value and increments (or decrements) by a specific value in each iteration.

Loop control statement

The loop control statement in a count-controlled loop is responsible for controlling the number of times the loop will run. It usually includes a conditional expression that checks if the counter variable has reached its limit or not. If the condition is true, then the loop continues to run, and it stops as soon as the condition becomes false.

Example (using a "for" loop)

A "for" loop is an example of a count-controlled loop. The syntax of a "for" loop includes a counter variable, a loop control condition, and an increment/decrement statement. Here's an example of a "for" loop that prints numbers from 1 to 5: ``` for (int counter = 1; counter <= 5; counter++) { print(counter); } ``` In this example, the counter variable `counter`, starts at 1, the loop control condition checks that `counter` is less than or equal to 5, and the increment statement `counter++` increases the value of `counter` by 1 in each iteration. When `counter` becomes 6, the loop ends.
