Learn C Programming

By: Jeff Szuhay

Overview of this book

C is a powerful general-purpose programming language that is excellent for beginners to learn. This book will introduce you to computer programming and software development using C. If you're an experienced developer, this book will help you to become familiar with the C programming language. This C programming book takes you through basic programming concepts and shows you how to implement them in C. Throughout the book, you'll create and run programs that make use of one or more C concepts, such as program structure with functions, data types, and conditional statements. You'll also see how to use looping and iteration, arrays, pointers, and strings. As you make progress, you'll cover code documentation, testing and validation methods, basic input/output, and how to write complete programs in C. By the end of the book, you'll have developed basic programming skills in C, that you can apply to other programming languages and will develop a solid foundation for you to advance as a programmer.

Using nested if()… else… statements

Sometimes, we can make the logic of if()… else… statements clearer by nesting if()… else… statements within either one or both clauses of the if()… else… statements.

In our isLeap() example, someone new to the intricacies of Gregorian calendar development and the subtleties of century leap year calculation might have to pause and wonder a bit about our if/else fall-through logic. Actually, this case is pretty simple; much more tangled examples of such a logic can be found. Nonetheless, we can make our logic a bit clearer by nesting an if … else … statement within one of theif()… else…clauses.

Copy leapYear2.c to leapYear3.c, which we will now modify. Our isLeap() function now looks like this:

bool isLeapYear( int year )  {
bool isLeap = false;

// Leap years not part of Gregorian calendar until after 1752.
if( year < 1751...
