Programming in C, const qualifier
Question1: Explain what is const qualifier? Ans : The const qualifier is used with a data type of declaration to specify a constant value. Some examples of const qualifiers are: Const int COUNT=5; Const float PI=3.14; The same thing can also be achieved using #define preprocessor as given below. #define COUNT 5 #define PI 3.14 In most of the situations there is no difference between using define or const qualifier. The only difference is define is a preprocessor directive that simply replaces a symbol with a constant value throughout the program. The const qualifier declares a variable type and assigns it a constant value. It has advantage at advance level of programming in C language.
