Introduction
I have used Swift for windows 1.9 for debugging purpose. But you can use any Swift programming language compiler as per your availability.
Write a Swift program to test if a given string starts with “test”
import Foundation
func checkstring(_ input: String) -> Bool {
if input.hasPrefix("test")
{
return true
}
else
{
return false
}
}
print(checkstring("testpqrsab"))
print(checkstring("testabpqrsab"))
print(checkstring("pqrs"))
print(checkstring("abpqrs"))Result
