Question
If you run the following code through Valgrind, which of the following errors will be reported? Check all that apply.
int main() { const int MAX_LENGTH = 10; int * myArray = new double[MAX_LENGTH]; for (int i = 0; i <= MAX_LENGTH; ++i) { cout << myArray[i]<< endl; } delete[] myArray; }Invalid read
Invalid write
Invalid free()
Mismatched free() / delete / delete []
Mismatched free() / delete / delete
Uninitialized value
Memory leak
None of the above
Expert Solution
arrow_forward
Step 1
Ans.
for the code:
q.cpp
#include<iostream>
using namespace std;
int main()
{
const int MAX_LENGTH = 10;
int * myArray = new int[MAX_LENGTH];
for (int i = 0; i <= MAX_LENGTH; ++i)
{ cout << myArray[i]<< endl; }
delete[] myArray;
return 0;
}
Valgrind errors:
Invalid read
Uninitialized value

- The following program generates an error. Why? finalintNUM_ELEMENTS=5;int[] userVals = new int[NUM_ELEMENTS];int i;userVals[0] = 1;userVals[1] = 7;userVals[2] = 4;for (i = 0; i <= userVals.length; ++i) {System.out.println(userVals[i]);} a. Variable i is never initialized. b. The array userVals has 5 elements, but only 3 have values assigned. c. The integer NUM_ELEMENTS is declared as a constant d. The for loop tries to access an index that is out of the array's valid range.
