Swift While Loop
While loop are used to iterates block of statement under terminate condition. This loop are executed when terminated are not invalid.
//set initial point
var fines=0
//Executed the statement until of satisfies
//Given condition is not (fines not greater than 200).
while fines <= 200{
print("Fines are \(fines)")
fines+=50 //Modified terminating condition
}
print("After While loop Fines :\(fines)")
Output
Fines are 0
Fines are 50
Fines are 100
Fines are 150
Fines are 200
After While loop Fines :250
When if we are need to execute block of statement minimum at least once. Then we can use alternative from of while loop.
//set initial point
var fines=250
repeat{
print("Fines are \(fines)")
fines+=50 //Modified terminating condition
}while fines <= 200
print("After While loop Fines :\(fines)")
Output
Fines are 250
After While loop Fines :300
That is similar to do-while loop in c, c++ and java programming.
