Frequently Asked Questions About KS3 Programming Iteration
What is a loop construct?
A loop construct is a programming construct that allows a section of code to be executed repeatedly. There are different types of loops, such as for loops, while loops, and do-while loops.
What is a for loop?
A for loop is a loop construct that allows a programmer to iterate over a range of values or a collection of items. The syntax for a for loop is:
for (initialization; condition; increment/decrement) {
// code to be executed
}
What is a while loop?
A while loop is a loop construct that repeatedly executes a block of code while a given condition is true. The syntax for a while loop is:
while (condition) {
// code to be executed
}
What is a do-while loop?
A do-while loop is a loop construct that is similar to a while loop, but the block of code is executed at least once before the condition is checked. The syntax for a do-while loop is:
do {
// code to be executed
} while (condition);
What is a foreach loop?
A foreach loop is a loop construct that allows a programmer to iterate over a collection of items, such as an array or a list. The syntax for a foreach loop is:
foreach (variable in collection) {
// code to be executed
}
It is also known as for-each loop, it is used to traverse through the elements of a collection, like an array, list, set etc. It is a concise way to iterate over a collection, it can be a array, list, set etc.
