Macros are preprocessor directives that are defined using #define directive. Macros consist of two parts Macro_Name, & Macro_Substitution_Text.
Before the source code gets complied, the preprocessor will check for the presence of macros. & wherever it found that macro simply replaces that macros with substitution text.

Macros are not Type Safe.

stack is a last in, first out (LIFO).It is characterized by only three fundamental operations: push, pop and stack top.

The queue is a First-In-First-Out (FIFO) data structure. In a FIFO data structure, the first element added to the queue will be the first one to be removed.

char* f() return "hello:"; void main() {char *str=f(); }

Given an int variable n that has already been declared and initialized to a positive value, and another int variable j that has already been declared, use a do...while loop to print a single line consisting of n asterisks. Thus if n contains 5, five asterisks will be printed. Use no variables other than n and j .

Given that two int variables, total and amount , have been declared, write a sequence of statements that: initializes total to 0 reads three values into amount , one at a time. After each value is read in to amount , it is added to the value in total (that is, total is incremented by the value in amount ). Instructor's notes: If you use a loop, it must be a for loop. And if you use a loop control variable for counting, you must declare it.
