What is the difference between a while loop and a for loop?

• For loops can use conditional statements and while loops cannot
• While loops repeat a set number of times and for loops repeat until their condition is false
• For loops repeat a set number of times and while loops repeat until their condition is false
• For loops can be used in a function and while loops cannot
