Question

24. Consider the following C++ code. (6, 8) string seasons [4](*Winter", "Spring", "Summer", "Falla) stringstrPtr; strPtr new string[5]; for (int į = 0; i < 4; i++) strPtr liseasons [i] a. Write a C++ code that outputs the contents of the array to whiclh strPtr points. Write the C++ statement that deallocates the memory space occu- pied by the array to which strptr points b.

Answer 1

a.

To print the contents of array, use the cout<< standard output stream within for loop

1 #include <iostream> 3 using namespace sta; 4 5 int main() 8 9 10 string seasons [4]-f"Winter", "Spring" , "Summer", "Fall"; string strptr; strptr -new string[5]; for (int i-0; i<4; i++ strptr[i]-seasons[il; cout <<strptr[i]<<endl; 12 14 15 16 17 return Winter Spring Summer Fall . . Program finished with exit code 0 Press ENTER to exit console

b.

Using delete operator, we deallocates the memory allocated by using new operator dynamically

delete[] strPtr;   //freed the block of memory allocated to array

#include <!ostream» 2 using namespace sta; 4 int main() 6 string seasons [4]-f"Winter", "Spring" , "Summer", "Fall"; string *strptr; strptr -new string[5] for (int 1-0; i<4; i++ 8 9 strptr[i]-seasons[il; cout <<strptr[i]<<endl; //prints the contents of array 13 cout << sizeof(strptr)くくendl; deletel] strptr; cout << sizeof (strptr)くくendl; return / 2. freed the block of allocated memory 17 18 19
