if answer all i will give a thumbs up odule 11: Exam 2 -Requires Respondus LockDown Browser+Webcam ted: Apr 13 at 2:57pm uiz Instructions 80 minute exam Exam may NOT be stopped and restarted Try to answer all questions partial credit will be given when You can assume the following libraries and functions are available for all questions on the exam necessary e Bincludesstdio.h> printf and scanf includesctype.hs tolower and toupper You do not need to write a complete program unless the question asks for a complete program read each question carefully D Question 5 5 pts Write a function definition called GameSurvey that takes one character argument/parameter called called pricePtr. The function has a void return type. When the variable argument gameS contalins the character x or X. print the word XBox and store 299.99 in the "value at" pricePtr When gameS contains the character p or P print the word Playstation and store a 4 t gameS and one pointer to a double 99.99 When gameS contains anything else, store a 0.0 ??.?.IE????x'x,EE MacBook Ar 30 0

Explanation / Answer

============================================================================

#include <stdio.h>

#include <stdlib.h>

// GameSurvey function :Q5

void GameSurvey (char gameS, double* pricePtr) {

if (gameS == 'x' || gameS == 'X'){

printf(" Xbox");

*pricePtr = 299.99;

}

else if (gameS == 'p' || gameS == 'P'){

printf(" Playstation");

*pricePtr = 499.99;

}

else {

*pricePtr = 0.0;

}

// Loop for sum of all integers given by user : Q6

void SumOfIntegers() {

int nums[45]; // Number array

int counter = 0; // for counting

int sumTotal = 0; // for storing sum of integers

// Read input from user

for (counter = 0; counter < 45; counter++) {

printf(" Enter Integer %d : ", counter+1);

scanf("%d",&nums[counter]); //Stores the input to array

sumTotal = sumTotal + nums[counter]; //Calculates the sum of integers

}

//Print the array

printf(" The Integer array is: ");

for (counter = 0; counter < 45; counter++)

{

printf("%d ", nums[counter]); // Print the array Element

}

printf(" Sum of Integers: %d", sumTotal); // Print sum.

}

// Question No. 7

void DisplayLargeNumbers(double numList[], int count, double large) {

int counter = 0; //for counting

printf(" The numbers larger than or equal to %g are: ",large); //%g to avoid zeros afte decimal

// we run the counter till we reach "count" number of elements

for(counter = 0; counter < count; counter++){

if(numList[counter] >= large) { //If any nmber is larger than 'large'

//Print that larger number

printf(" %g ", numList[counter]); // %g used to for not to print trailing zeroes.

}

// Main program to test our functions

int main(void) {

double price;

double numList[] = {23.4, 56.8, 12.0, 33.67, 80, 76.12345678, -23};

// Testing Question No. 5

GameSurvey('x',&price);

printf(" Price: %.2lf", price); //%.2 for 2 digits after decimal point

GameSurvey('P',&price);

printf(" Price: %.2lf", price);

// Testing Sum of Integers. Question Number 6

SumOfIntegers();

// Testing Question Number 7

DisplayLargeNumbers(numList, 7, 23.4);

//puts("!!!Hello World!!!"); /* prints !!!Hello World!!! */

return EXIT_SUCCESS;

}

Main Program for Q8 and functions specified in question.

============================================================================

#include <stdio.h>

void GetAmount(double *amountPtr) {

printf(" Enter double number: ");

//getamount will have the address, which needs to be passed to scanf

scanf("%lf",amountPtr);

}

void AddOrSubtract(double amount, double* totalPtr) {

int option;

printf(" What do you want to do? Add[1] or Subtract[2]: ");

printf(" Please Enter the option: (1 or 2): ");

scanf("%d",&option); // read option

if(option == 1) { // Selected Add

*totalPtr = *totalPtr + amount; //Add amount to totalPtr value

}

else if (option == 2) { // Selected Subtract

*totalPtr = *totalPtr - amount; //Subtract the amount.

}

else { //Entered option other than 1 and 2

printf(" Not Recognized");

}

int main() {

double amount; // To read the amount by GetAmount function

double total=0; // To calculate Total

//Passing amount by reference. So that we can pass it to the AddorSubtract

GetAmount(&amount);

// We are passing the amount returned by the GetAmount function and reference to total

AddOrSubtract(amount, &total);

printf(" Total Calculated: %g", total); //Prints the total.

// Running once more to check the total.

GetAmount(&amount);

AddOrSubtract(amount, &total);

printf(" Total Calculated (2nd Run): %g", total); //Prints the total.

return 0;

}
