Answer:

A nested loop is a loop that runs within another loop. Put it in another sense, you have an inner loop that is inside an outer loop. In this scenario, the inner loop is performed a number of times as specified by the outer loop. For each turn on the outer loop, the inner loop is first performed.

427. Which of the following operators is incorrect and why? ( >=, <=, <>, ==)

Answer: <> is incorrect. While this operator is correctly interpreted as "not equal to" in writing conditional statements, it is not the proper operator to be used in C programming. Instead, the operator != must be used to indicate "not equal to" condition.

430. What are header files and what are its uses in C programming?

Answer: Header files are also known as library files. They contain two essential things: the definitions and prototypes of functions being used in a program. Simply put, commands that you use in C programming are actually functions that are defined from within each header files. Each header file contains a set of functions. For example: stdio.h is a header file that contains definition and prototypes of commands like printf and scanf.

432. What are variables and it what way is it different from constants?

Answer: Variables and constants may at first look similar in a sense that both are identifiers made up of one character or more characters (letters, numbers and a few allowable symbols). Both will also hold a particular value. Values held by a variable can be altered throughout the program, and can be used in most operations and computations. Constants are given values at one time only, placed at the beginning of a program. This value is not altered in the program. For example, you can assigned a constant named PI and give it a value 3.1415 . You can then use it as PI in the program, instead of having to write 3.1415 each time you need it.

433. How do you access the values within an array?

Answer: Arrays contain a number of elements, depending on the size you gave it during variable declaration. Each element is assigned a number from 0 to number of elements-1. To assign or retrieve the value of a particular element, refer to the element number. For example: if you have a declaration that says "intscores[5];", then you have 5 accessible elements, namely: scores[0], scores[1], scores[2], scores[3] and scores[4].
