    In order to effectively develop C programs, it will be necessary to understand the rules that are used for the implicit conversion of floating point and integer values in C. These are mentioned below. Note them carefully. An arithmetic operation between an integer and integer always yields an integer result.…

    C constants can be divided into two major categories: Primary Constants:  Secondary Constants: At this stage we would restrict our discussion to only Primary Constants, namely, Integer, Real and Character constants. Let us see the details of each of these constants. For constructing these different types of constants certain rules…

    A character denotes any alphabet, digit or special symbol used to represent information. Here is the list of valid character set (Alphabets, Numbers and Symbols) allowed in C. The alphabets, numbers and special symbols when properly combined form constants, variables and keywords. Let us see what are ‘constants’ and ‘variables’…

    We have seen the first c program, Now let us look at the instructions that we used in these programs. There are basically three types of instructions in C: Type Declaration Instruction - To declare the type of variables used in a C program. Arithmetic Instruction - To perform arithmetic operations between…

    An entity that may vary during program execution is called a variable. Variable names are names given to locations in memory. These locations can contain integer, real or character constants. In any language, the types of variables that it can support depend on the types of constants that it can handle. This…
