Question $1[15$ marks$]$

Two students who work for a Data Centre have written a program in C$++$ which is capable

of converting any number into a $12$ bit binary number system. The program has two soft

buttons. The first is $$Unsigned$$ & second is $$Signed$$ which indicates the type of number

that is initially entered in the command prompt. For the $$Signed$$ function the programs

uses the $1$s complement approach. These are D$0$ through to D$11$ where D$0$ represents the

most significant bit while D$11$ the least significant bit.

a$)$ What output would the program give for the inputs $($i$.),($ii$.)$ & $($iii$.)$ in $$Unsigned$$ Mode.

i$.718[2$ marks$]$

ii$.19$C$16[2$ marks$]$

iii. $47610[2$ marks$]$

b$)$ What would be the output for $$Signed$$ mode with the new inputs $($i$.),($ii$.)$ & $($iii$.).$

i$.-20[2$ marks$]$

ii$.+37[2$ marks$]$

iii. $-15[2$ marks$]$
