Question
Which of the following functions DOES NOT have a memory leak?
Select one:
void func(string word) { int* ptr = new int[2]; ptr[0] = word.size(); delete ptr; }
void func(string word) { int* ptr = new int; *ptr = word.size(); }
void func(string word) { int* ptr = NULL; int len = word.size(); ptr = &len; cout << "Length of " << word << " is " << *len << endl; }
Expert Solution
