C++

1) Array testGrades contains NUM_VALS test scores. Write a for loop that sets sumExtra to the total extra credit received. Full credit is 100, so anything over 100 is extra credit. Ex: If testGrades = {101, 83, 107, 90}, then sumExtra = 8, because 1 + 0 + 7 + 0 is 8.

#include <iostream>
using namespace std;

int main() {
const int NUM_VALS = 4;
int testGrades[NUM_VALS];
int i = 0;
int sumExtra = -9999; // Assign sumExtra with 0 before your for loop

testGrades[0] = 101;
testGrades[1] = 83;
testGrades[2] = 107;
testGrades[3] = 90;

/* Your solution goes here */

cout << \"sumExtra: \" << sumExtra << endl;
return 0;
}

2) 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:

Note that the last element is not followed by a comma, space, or newline.

#include <iostream>
using namespace std;

int main() {
const int NUM_VALS = 4;
int hourlyTemp[NUM_VALS];
int i = 0;

hourlyTemp[0] = 90;
hourlyTemp[1] = 92;
hourlyTemp[2] = 94;
hourlyTemp[3] = 95;

/* Your solution goes here */

cout << endl;

return 0;
}

Solution

Answer:

1)

for(i = 0;i < NUM_VALS; i++) {

if(testGrades[i] > 100)

sumExtra = sumExtra + (testGrades[i]-100);

}

2)

for ( i = 0; i < NUM_VALS; i++)

{

cout<<hourlyTemp[i];

if(i < NUM_VALS -1)

{

cout<<\", \";

}

}
