LAB 4 – if-else You wish to create a simple educational game for pre-school children to learn number sorting for either descending or ascending order. Your application only supports 3 numbers. Firstly, it gets 3 numbers from user. Then, it asks user for the order preference (either descending (enter 'd' or D)' or ascending (enter 'a' or 'A')) and finally displays the numbers in the preferred ordering. Write a modular program to produce this application. SAMPLE OUTPUT: Your sorting preference? D Enter 3 numbers for sorting: -93 8 42 Output: You entered: -93 8 42 Descending order is: 42 8 -93
Assign numMatches with the number of elements in userValues that equal matchValue. userValues has NUM_VALS elements. Ex: If userValues is {2, 1, 2, 2} and matchValue is 2, then numMatches should be 3. Your code will be tested with the following values: matchValue: 2, userValues: {2, 1, 2, 2} (as in the example program above) matchValue: 0, userValues: {0, 0, 0, 0} matchValue: 10, userValues: {20, 50, 70, 100} (Notes) 324758.2040686.qx3zgy7 3 int main(void) { const int NUM VALS = 4; int userValues[NUM_VALS]; int i; int matchvalue; int numMatches = -99; // Assign numMatches with e before your for loop 4 1 test 5 passed 6 7 All tests 8 passed 9 scanf ("%d", &matchValue); 10 11 for (i = 0; i < NUM_VALS; ++i) { scanf("%d", &(userValues[i])); } 12 13 14 15 16 * Your solution goes here */ 17 18 printf("matchvalue: %d, numMatches: %d\n", matchValue, numMatches); 19 20 return 0;

Double any element's value that is less than controlValue. Ex: If controlValue = 10, then dataPoints = {2, 12, 9, 20} becomes {4, 12, 18, 20}. #include <iostream>using namespace std; int main() { const int NUM_POINTS = 4; int dataPoints[NUM_POINTS]; int controlValue; int i; cin >> controlValue; for (i = 0; i < NUM_POINTS; ++i) { cin >> dataPoints[i]; } /* Your solution goes here */ for (i = 0; i < NUM_POINTS; ++i) { cout << dataPoints[i] << " " ; } cout << endl; return 0;}
