CPS $1231$ SI Session: Exercise $4$

Mathematical Functions, Characters, and Strings $($Ch$4)$

$4.$ Write a program that prompts the user to enter a four binary numbers as a string and displays its

corresponding decimal value. Here are sample runs.

$--$Sample Run$--$

$4-1.$Explain the process on how to calculate from binary $($base $2)$ to decimal $($base $10).(1$ point$)$

$4-2.$Draw a flowchart for your program? $(1$ point$)$

$4-3.$What type of invalid inputs are possible? $(1$ point$)$

$4-4.$Name your class $($program$)$ SISession$4$ and show your running code. $(2$ point$)$

$($Extra$)$ Handle all invalid inputs mentioned in $4-3.$

$($Extra$)$ Code your program from decimal $($base $10)$ to binary $($base $2)$
