Step by step
Solved in 2 steps
- Do void and NULL pointers differ? Support your answer with examples. Tabulate the differences.Make the value pointed to by the -pointer Ptr zero1. Update t to point to c. Use a pointer dereference to change the value of c to 555. Verify that it worked by adding a printout. Does this change any of the other values? 2. Change the value of c again using a direct assignment. Verify that the pointer t sill points to the value by printing the result of dereferencing it.
- Complete the following function using pass-by-reference: void findMax(int &max, int a) which assigns value ‘a’ to ‘max’ if a > max. Write a pseudo-code then implement a program in C language to find the maximum in a sequence of numbers using this function.Dangling and wild pointers are known to be problems with pointers Justify given statement with the help of given examplesWhat is the result of multiplying ptr by four? Assuming ptr is an int reference, the following occurs:
- “Array name can act as aconstant pointer”. Justify thegiven statement bydistinguishing array name withpointer variable and suitableexamples. This is a question of c languageIn C++ Create an array of head pointers, statically allocated of size 101 of that type: Now, create a pointer that can point to the first element: Show how to dynamically allocate an array of 101 elements of head pointers: Write the code to initialize each element to NULL: Rewrite the code to initialize each element to NULL using pointer arithmetic:Write a recursive function named “oddRec” that takes the address of the array and the number of elements as a parameter and returns the number of odd numbers in the array. (Do not use global variable)
