Convert the following while loop to a for loop: int count \(=0\) while (count \( < 50\) ) \\{ cout \( < < \) "count is \(" < < \) count \( < < \) endl count \(++\) \\}
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(n) __________ is a special value that marks the end of a series of values.
