When variables are declared, are they located in memory contiguously? Write a program with the declaration: char a, b, c, *p, *q, *r; And print out the locations (addresses) that are assigned to all these variables by your computer. Are the locations in order? If the locations are in order, are they increasing or decreasing? Is the address of each pointer variable divisible by 4? If so, this probably means that each pointer value gets stored in machine word. Double check the results using sizeof() for char and for char". (Hint: if you want to see addresses printed as decimal numbers rather than hexadecimals, it is usually safe to cast an address as unsigned long and use the %lu format).
