Encapsulation brings together the data and the methods that manipulate the data into a single component and protects them from outside interference. In essence, encapsulation involves bundling the data as well as the functions that use the data. Data encapsulation in lead to the very important concept of data hiding.Encapsulation in C++ is implemented using classes that are user defined data types. These classes contain data types as well as methods that are bound together.A program that represents encapsulation in C++ using classes is given as follows.Example Live Demo#include using namespace std; class EncapsulationDemo { private: int length, ...

Abstraction involves providing only the pertinent information to the outside world and hiding the background details. It relies on the separation of interface and implementation for programming.Classes provide abstraction in C++. They provide public methods for the outside world to manipulate data and keep the rest of the class structure to themselves. So the users can use the class as required without knowing how it has been implemented internally.A program to implement abstraction in C++ using classes is given as follows.Example Live Demo#include using namespace std; class Abstraction { private: int length, breadth; public: void setValues(int ...

Classes are the prime features of C++ as they support OOPS concepts and are user defined data types. Classes provide the specification for an object and contain data variables as well as functions to manipulate the data in a single package.Class DefinitionsA class definition starts with the keyword class and then the class name. After that the class body is defined. It is enclosed by curly braces. A class definition should either contain a semicolon or a list of definitions after it.An example of a class definition in C++ is as follows.class student { int rollno; char name[50]; ... Read More

The function fflush(stdin) is used to flush the output buffer of the stream. It returns zero, if successful otherwise, returns EOF and feof error indicator is set.Here is the syntax of fflush(stdin) in C language,int fflush(FILE *stream);Here is an example of fflush(stdin) in C language,Example Live Demo#include #include int main() { char s[20] = "Helloworld"; printf("The string : %s", s); fflush(stdin); return 0; }OutputThe string : Helloworld

The function ispunct() is used to check that the passing character is a punctuation or not. It returns zero, if it is not a punctuation, otherwise it returns a non-zero value.Here is the syntax of ispunct() in C language, int ispunct(int character);Here is an example of ispunct() in C language, Example Live Demo#include #include int main() { int a = '!'; int b = 'a'; if(ispunct(a)) printf("The character is a punctuation."); else printf("The character is not a punctuation."); if(ispunct(b)) printf("The character is a punctuation."); else printf("The character is not a ...

The function strspn() is used to calculate the length of substring of first string which is present in second string. It returns the length of that substring.Here is the syntax of strspn() in C language,size_t strspn(const char *string1, const char *string2);Here is an example of strspn() in C language,Example Live Demo#include #include int main() { const char s1[] = "Helloworld!"; const char s2[] = "Hello"; int length = strspn(s1, s2); printf("The length of string : %d", length); return 0; }OutputThe length of string : 5

The function strpbrk() is used to find the first character of first string and matches it to any character of second string. It returns NULL, if no matches are found otherwise, it returns a pointer to the character of first string that matches to the character of second string.Here is the syntax of strpbrk() in C language, char *strpbrk(const char *string1, const char *string2)Here is an example of strpbrk() in C language, Example Live Demo#include #include int main () { const char s1[] = "Helloworld"; const char s2[] = "Blank"; char *result; result = strpbrk(s1, ...
