### Computer Science Quiz#### Question 1: Hexadecimal Representation**Question:** How many hexadecimal digits are used when representing a nibble in hex form?**Options:**- 1- 3- 2- 0#### Question 2: Function Parameters and Stack Alignment**Scenario:** Patti the Programmer decides to create a function with three int16 parameters, sending all three by-reference. Will she need to pad her function’s activation record to make it 32-bit aligned?**Options:**- The answer will depend on how many registers get preserved on the stack.- Yes- No- The answer will depend on the value of the passed parameters.#### Question 3: Memory Usage for Function Parameters**Question:** How many bits of stack memory are used when passing an int16 variable by-value to a function?**Options:**- 32- 64- 16- 8### Explanation of Concepts1. **Hexadecimal Digits and Nibbles:** - A **nibble** equals 4 bits. - Each hexadecimal digit represents exactly 4 bits.2. **Stack Alignment:** - Aligning data in memory can be necessary to meet the processor's requirements and improve performance. - A 32-bit alignment means data is aligned at addresses divisible by 4 bytes.3. **Stack Memory for int16:** - An **int16** is a 16-bit integer, meaning it occupies 16 bits in memory when passed by value.

The above question is solved in step 2 :-

C programing Write a program to model a simple calculator. Each data line should consist of the nextoperation to be performed from the list below and the right operand. Assume the left operandis the accumulator value (initial value of 0). You need a function scan_data with two outputparameters that returns the operator and right operand scanned from a data line. You need afunction do_next_op that performs the required operation. do_next_op has two inputparameters (the operator and operand) and one input/output parameter (the accumulator).The valid operators are:+ add- subtract* multiply/ divide^ power (raise left operand to power of right operand)q quitYour calculator should display the accumulator value after each operation. A sample run follows.+ 5.0result so far is 5.0^ 2result so far is 25.0/ 2.0result so far is 12.5q 0final result is 12.5

binaryAddition functionThis function takes two static arrays, bit pattern length, and a third static array as its arguments. The function must populate the third array with the binary sum of the first two arrays in the given bit pattern length. Assume the first two arrays are populated with binary bits in the given bit pattern length. Moreover assume that all the arguments are valid.
