Pointer help, in c++, all questions use info from previous questions so can not seperate. answer all please

1) Declare a pointer that holds an address of an integer variable. 6 pts. 2) Given an array of integer values int valst] = {4, 7, 11, 1); assign to the pointer that you have declared in the question (1) the address of the second member of the array. Hint: there are two ways of doing that - you can use any. 10 pts. 3) Assuming that the pointer that you have declared previously holds the address of the first member of the array vals print out the value of the second member of the array vals using four distinct ways. 6 points for each.
