' characters. There should be \(15 \%\) characters in each row. # Write a nested loop that displays 10 rows of '#' characters. There should be \(15 \%\) characters in each row.

Convert the following do-while loop to a while loop: char sure; do \\[ \\{ \\] cout \( < < \) "Are you sure you want to quit? " \\[ \operatorname{cin}>>\text { sure } \\] While (sure \(1=\text { ' } \mathrm{Y} \text { ' } \& \& \text { sure } !=\text { 'N' })\)

Convert the following while loop to a for loop: int count \(=0\) while (count \( < 50\) ) \\[ \\{ \\] cout \( < < \) "count is \("<<\) count \( < < \) endl count \(++\) \\[ 3 \\]

Convert the following for loop to a while loop: \\[ \begin{array}{l} \text { for }(\operatorname{int} x=50 ; x>0 ; x--) \\ \\{ \end{array} \\] cout \( < < x< < \) seconds to \(g \circ \cdot \ln "\) \\}

T \(F\) The cout statement in the following program segment will display 5: \\[ \begin{array}{l} \text { int } x=5 ; \\ \t ext { cout } << x++; \end{array} \\]

\(\mathrm{T}\) F The while loop is a pretest loop.

\(\mathrm{T} \mathrm{F} \) All three of the for loop's expressions may be omitted.

\(\mathrm{T}\) F One limitation of the for loop is that only one variable may be initialized in the initialization expression.

T \(\mathrm{F}\) Variables may be defined inside the body of a loop.

T \(\mathrm{F}\) A variable may be defined in the initialization expression of the for loop.
