A(n) __________ is a sum of numbers that accumulates with each iteration of a loop.
Rewrite the following code, converting the while loop to a do-while loop: char doAgain \(=' y^{\prime}\) \\[ \text { int } \operatorname{sum}=0 \\] cout \( < < \) "This code will increment sum 1 or more times. \(| n "\) while ( (doAgain = = ' y') | | (doAgain = = 'Y') ) \(\\{\quad s u m++;\) cout \( < < \) "Sum has been incremented. Increment it again(y/n)? "; cin \(>>\) doAgain; \\} cout \( < < \) "Sum was incremented " \( < < \) sum \( < < "\) times. \(\backslash n "\)
A loop that evaluates its test expression after each repetition is a(n) __________ loop.
A(n)__________ is a variable that “counts” the number of times a loop repeats.
