Question

Write a for loop to print all NUM_VALS elements of array hourlyTemp. Separate elements with a comma and space. Ex: If hourlyTemp = {90, 92, 94, 95}, print: 90, 92, 94, 95 Your code's output should end with the last element, without a subsequent comma, space, or newline. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 #include using namespace std; int main() { const int NUM_VALS = 4; int hourlyTemp[NUM_VALS]; int i; for (i = 0; i < NUM_VALS; ++i) { cin >> hourlyTemp[i]; } /* Your solution goes here */ cout << endl; return 0; } 1 test passed All tests passed Run

Answer:

1. #include <iostream>
3. using namespace std;
5. int main()
6. {
7.    const int NUM_VALS = 4;
8.    int hourlyTemp[NUM_VALS];
9.    int i;
10.    
11.    for (i = 0; i < NUM_VALS; ++i)
12.    {
13.        cin >> hourlyTemp[i];
14.        
15.    }
16.    
17.    /* Your solution goes here */
18.    for(i = 0; i < NUM_VALS; ++i){
19.        
20.        if(i < NUM_VALS -1){
21.            cout<<hourlyTemp[i]<<",";
22.        }
23.        else{
24.            cout<<hourlyTemp[i];
25.        }
26.    }
27.    cout << endl;
28.    return 0;
29. }

Explanation:

The solution code is given from Line 18 - 26. To print the element from array one after another, we create a for loop to traverse through every element in the array (Line 18). Create an if condition to check if the current index i is not the last index, print the element followed with a comma (Line 20 -22). Otherwise print only the element (Line 23 - 25).
