Question

5. Write few lines of code that creates two arrays with malloc. Then write a statement that can create a memory leak. Discuss why you think your code has a memory leak by drawing the status of the memory after you use malloc and the line of the code you claim that creates a memory leak.

Answer 1

Answer:

 // function with memory leak  

void func_to_show_mem_leak()  {  

int *pointer;

pointer = malloc(10 * sizeof(int));

*(pointer+3) = 99;}  

 

// driver code  

int main()  

{  

    // Call the function  

   // to get the memory leak  

   func_to_show_mem_leak();  

     return 0;  }

Explanation:

Memory leakage occurs when programmers allocates memory by using new keyword and forgets to deallocate the memory by using delete() function or delete[] operator. One of the most memory leakage occurs by using wrong delete operator. The delete operator should be used to free a single allocated memory space, whereas the delete [] operator should be used to free an array of data values.
