Loops - Swift Programming

Loops repeat a block of code. A for loop is a direct way to walk through a range of numbers.

Sum a range

loops.swift

let limit = 
var total = 0

for value in 1...limit {
    total = total + value
}

print("limit=\(limit)")
print("total=\(total)")

let limit = 
var total = 0

for value in 1...limit {
    total = total + value
}

print("limit=\(limit)")
print("total=\(total)")

let limit = 
var total = 0

for value in 1...limit {
    total = total + value
}

print("limit=\(limit)")
print("total=\(total)")

closed range `1...limit` includes both endpoints.
