Why do we use loops?
Loops are used in programming to execute a set of instructions repeatedly. They help automate repetitive tasks and simplify code, making it more concise and easier to read. Using loops can also help reduce the amount of code needed to achieve a specific task.
What loop do we use when we want the code to run a specific number of times?
We use a for loop when we want the code to run a specific number of times. For example, if we want to print the numbers 1 to
10, we can use a for loop that iterates from 1 to 10.
What loop do we use when we don’t know the specific number of times? (consider the difference between a while loop and a for loop?)
We use a while loop when we don’t know the specific number of times we need to run the code. A while loop will continue to execute the code block as long as the specified condition is true. In contrast, a for loop is used when we know the number of iterations required, and it is more suitable when we need to execute code for a specific number of times.
What are the three parts of a for loop?
The three parts of a for loop are:
Initialization: This is where we initialize the loop variable to a specific value, typically the starting value.
Condition: This is the condition that is checked at the beginning of each iteration. If the condition is true, the loop continues to execute. If the condition is false, the loop stops.
Increment/Decrement: This is the statement that is executed at the end of each iteration. It updates the loop variable so that the condition is eventually false, and the loop stops.
