Complete each problem below as directed using valid C syntax:

R. Declare a function named average that takes an integer array and the size of the array as an argument. The return value is a double. S. If variable p is a pointer and points to the base address of an integer array, use variable P to set the value at index 5 of the array to the value 5. T Name a function in the C standard libraries e. in stdio.h) that uses pass by reference. U. Show the LC-3 assembly code for pushing the value in R5 onto the runtime stack. V. Declare a struct that holds an integer array of length 10 and a character array of length W. Declare a struct suitable for representing a linked list. X. Write an expression for an int value with an alternating bit pattern (e.g. 0101b) that fills up all 32 bits of the integer Hint: come up with an appropriate literal Y Write an expression that evaluates to true. You may not declare or use any variables
