Give the minimum size of each of the following C data structures, assuming that char values occupy byte, int and float values occupy four bytes, double values occupy eight bytes, and pointers occupy bytes. (a) char str[] = "Curly": (b) double *a[4][4]: (c) char *str[3] = {"Moe", "Larry", "Curly"}: (Include the space occupied by the string literals in your answer.) (d) union { int a: char b: float c[4]: }u: (e) struct { int a: char b: float c[4]: }s:...

Write a C++ function int calculate(char, int , int ) which takes a char of either ‘+’, ‘ ‘--’, ‘*’, or ‘/’ as operator and two integers as operands. The function should return the result of applying the corresponding operator on the operands if all of them are of proper types and values. It should throw a char exception if the operator is unknown and a char* exception if the operator is ‘/’ and the second operand is zero. Write...

Homework Part 1 Write a C program that declares and initializes a double, an int, and a char. You can initialize the variables to any legal value of your choosing. Next, declare and initialize a pointer variable to each of the variables Using printf), output the following: The address of each of the first three variables. Use the "Ox%x" format specifier to print the addresses in hexadecimal notation The value of each variable. They should equal the value you gave...
