To __________ a value means to decrease it by one.
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. \(\backslash n "\)
Each repetition of a loop is known as a(n) __________.
Write code that lets the user enter a number. The number should be multiplied by 2 and printed until the number exceeds \(50 .\) Use a while loop.
