Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards, then backwards. End each loop with a newline. Ex: If courseGrades = {7, 9, 11, 10), print: 7 9 11 10 10 11 9 7 Hint: Use two for loops. Second loop starts with i = NUM_VALS - 1. Note: These activities may test code with different test values. This activity will perform two tests, both with a 4-element array (int courseGrades[4]). Also note: If the submitted code tries to access an invalid array element, such as courseGrades[9] for a 4-element array, the test may generate strange results. Or the test may crash and report "Program end never reached", in which case the system doesn't print the test case that caused the reported message. 1 #include 2 3 int main(void) { 4 5 6 7 8 9 10 11 12 13 14 15} const int NUM_VALS = 4; int courseGrades [NUM_VALS]; int i; for (i = 0; i < NUM_VALS; ++i) { scanf("%d", & (courseGrades[i])); } *Your solution goes here */ return 0;

Assign numMatches with the number of elements in userValues that equal mato 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)
