Let us C programmes Solutions

# Let us C Chapter 1 : Introduction Let us C (by Yashavant Kanetkar) There are four important aspects of any language. They are 1) The way it stores data 2) The way it operates upon this data 3) How it accomplishes input and output 4) How it lets you control the sequence of execution of instructions in a program. This chapter explains first three of them. C is different from C++, C# and JAVA in following aspects. 1) C++, C# or Java make use of Object Oriented Programming (OOP). 2) Major parts of popular operating systems like Windows, UNIX, Linux is still written in C. 3) Device driver programs are exclusively written in C. 4) Speed is where C language scores over other languages. C Learning Steps The C Character Set Types of C Constants C constants can be divided into two major categories: (a) Primary Constants (b) Secondary Constants Types of C Constants Rules for Constructing Integer Constants (a) An integer constant must have at least one digit. (b) It must not have a decimal p...
