What are the differences between for and while loops in organizing repetitive operations in programming?

Main differences between for and while loops:

• for is usually used when the number of repetitions is known or when iterating over a collection. The for loop includes initialization, condition, and step in one line.
• while is suitable when the number of repetitions is unknown in advance, and the loop continues as long as the condition is true.

Example of for:

for (i in 1..5) {
    println(i)
}

Example of while:

var i = 1
while (i <= 5) {
    println(i)
    i++
}

Thus, for is convenient for iterating over ranges or collections, while is suitable for loops with conditions depending on dynamic factors.
