Tech Differences

Array and structure both are the container data type. The major difference between an array and structure is that an "array" contains all the elements of "same data type" and the size of an array is defined during its declaration, which is written in number within square brackets, preceded by the array name. A "structure" contains all the elements of "different data type", and its size is determined by the number of elements declared in a structure when it is defined. There are some more … [Read more...]

"If-else" and "switch" both are selection statements. The selection statements, transfer the flow of the program to the particular block of statements based upon whether the condition is "true" or "false". The fundamental difference between if-else and switch statements is that the if-else statement "selects the execution of the statements based upon the evaluation of the expression in if statements". The switch statements "selects the execution of the statement often based on a keyboard … [Read more...]

The "pointer" and "reference" both are used to point or refer an another variable. But, the basic difference among both of them is that a pointer variable points to a variable whose memory location is stored in it. The reference variable is an alias for a variable which is assigned to it. The comparison chart below explores the other differences between a pointer and a reference.

The "&" and "&&" both are the operators, used to evaluate the conditional statements. The & operator is a logical as well as, a bitwise operator. The && operator is purely a Logical operator. The basic difference between the & and && operator is that the & operator evaluate both sides of the expression whereas, the && operator evaluates only the left-hand side of the expression to obtain the final result. Let us understand the other differences … [Read more...]

Inheritance allows, code reusability and the polymorphism is, the occurrence of one function with different form. The basic difference between inheritance and polymorphism is that inheritance allows the already existing code to be reused again in a program, and polymorphism provides a mechanism to dynamically decide what form of a function to be invoked.

Abstraction is a process of collecting important information which will create a base for building up a complex system. Encapsulation is a process of making a complex system easier to handle for an end user, without worrying about its internal complexities. The basic difference between "abstraction" and "encapsulation" is that abstraction focuses on "identifying the necessary components for building a system" whereas, encapsulation focuses on "hiding the internal complexities of a … [Read more...]

C++ allows all the five ways that the C language provided to create a custom data. Those five ways are 'structure', 'bit-field', 'union', 'enumeration', 'typedef'. In the article below we are going to study the difference between structure and union. The structure and union both are the container data types that can hold data of any "type". The one major difference that distinguishes structure and union is that the structure has a separate memory location for each of its members whereas, the … [Read more...]

Both a structure and a class provides a way to create a customized data type which can be used further to create instances. C++ expands the role of structure to create a class. Both structure and class, are similar in all respect except one difference that, structure by default have all its member as "public", and class by default have all its member "private". Let's study the difference between structure and class by using comparison chart. Content: Structure Vs Class Comparison Chart … [Read more...]

There is a close relationship between array and pointer. The pointer can be used to access the array elements, accessing the whole array using pointer arithmetic, makes the accessing faster. There is a basic difference between a pointer and an array that is, an array is a collection of variables of similar data type whereas the pointer is a variable that stores the address of another variable. There are some other differences between an array and a pointer which are discussed below in the … [Read more...]
