Pointer to a single memory location Declare a pointer to doubles, called ptrA Use ptrA to allocate a single double memory location (not an array) Using ptrA read in a value for the allocated memory location Using ptrA add 2 to the value in the allocated memory location and store the res back to the same location. Using ptrA, write out the value from the allocated memory location. De-allocate the memory location that was allocated using ptrA b) Pointer to an array Declare a second pointer to doubles, called ptrB Use ptrB to allocate an array of 20 doubles Use a loop to assign each of the allocated array locations a value of 3 Change the value in the fifth array position by multiplying it by 2 De-allocate the entire array space that was allocated using ptrB
