Question

For this problem, assume the following declaration: int i a) Declare a pointer to an int, named iptr b) Point iptr at i c) Write a line of code that assigns to i the value 17, without actually using i on the left-hand side of an assignment statement For this problem, you must use malloc. Recall that malloc takes as its only parameter the number of bytes to allocate and returns a void pointer, i e., the return type is void a) Write line of code that dynamically allocates 100 int values on the heap using a call to malloc. Point at this memory with an appropriately-declared pointer, named arr. b) Fill in the if statement that checks to see if the previous malloc succeeded if printf ("malloc succeeded. c) Write a line of code that frees up the memory at which arr points For this problem, assume the following: int myArray [99] Without using ls... a) what is the address of the fifth element of my Array? b) What is the value of the seventh element of my Array? Write a void function that can be used to swap the value of two ints. Give the function header and body void swap //swap

Please repost other in separate post.

PLease let me know in case of any issue in ansered part.

Part1)

   b)
       iptr = &i;

   c)
       *iptr = 17;

Part2)
  
       a)
           int *arr = (int *)malloc(100*sizeof(int));

       b)
           if( arr != NULL){
               printf("malloc succeeded");
           }
