Question

What is the output of following if y = 11 initially?
(i) 10 * + + y - 1;
(ii) + + y + y ++;​

Answer 1

i) 119                     << 10 x ++ y - 1;

ii) 23

Hope I helped

Answer 2

Answer:

Initially, y=11

• 10 * ++y - 1

Apply BEDMAS Rule

$\begin{gathered} \orange{ \tt{10* + + y - 1}} \\ :\implies 10* + + 11 - 1 \\ : \implies 10*12 - 1 \\ : \implies120 - 1 \\ : \implies \orange{ \underline{ \boxed{119}}} \end{gathered}$

• ++y + y++

Note here one is prefix and the other is postfix

$\begin{gathered} \orange{ \tt + + y + y + + } \\ : \implies\tt + + 11 +y + + \\ : \implies12 + 12 + + \\: \implies 12 + 12 \: \\ \tt\green{\backslash \backslash \: now \: a \: becomes \: 13} \\ : \implies \bold{ \orange{ \underline{24}}} \end{gathered}$
