I n programming how does on know where to put loops and which one?
In: Other
Generally, “for” loops are used when there is a definite number of times you need to do something, and “while” loops are used when the number of loops needed is unknown.
I usually think of what I want to accomplish ( like run through columns 1 to 10) and the end goal. Loops for me got a lot easier to understand with time
May sound a bit unusual, but based on the question you’re asking. And in a comment you said you’re just trying to learn. I can reccomend a few games you can play to get you familiar with coding and how to structure programs. One I would reccomend is ‘Human Resource Machine’. This game focuses heavily on loops and can somewhat give you an idea of how functions come into play.
When you want to perform an action over and over, like processing a record or doing some computations.
What type? It’s all based on a condition being met. It may be the length of a sentence, and doing something with each character. Or it may be counting down a number to zero.
When that condition is met, then the loop terminates and processing continues.
What are you trying to accomplish?
A for loop is used when you want to do something a specific number of times. They’re often used if you need to perform some operation on every member of an array. A for each loop is pretty similar to a for loop, just with slightly different a syntax.
A while loop is used when you need the loop to keep executing the loop and unknown number of times until some condition is met. A do while loop is similar to a while loop but is guaranteed to execute at least once.
