"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 according to 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. Content: Pointer Vs Reference Comparison Chart Definition Key Differences … [Read more...]

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. Content: Inheritance Vs Polymorphism Comparison Chart Definition Key Differences Conclusion Comparison … [Read more...]

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. The Structure and class, are almost similar in all respect except the significant one difference that, structure by default have all its member as “public”, and class by default have all its member “private”. Furthermore, polymorphism and inheritance are not supported by the structure, but classes support polymorphism … [Read more...]

Array and pointer both are programming elements. An array is a data structure that holds variables of the same data type. On the other hand, the pointer is a kind of variable that holds the address of another variable which has the same data type as of pointer variable. We can even use a pointer to access the array elements. Accessing the whole array using pointer arithmetic, makes the accessing faster. While implementing an array a fixed memory size is allocated to array elements. … [Read more...]

In C++ and Java, the iteration statements, for loop, while loop and do-while loop, allow the set of instructions to be repeatedly executed, till the condition is true and terminates as soon as the condition becomes false. Conditions in iteration statements may be predefined as in for loop or open-ended as in while loop. There are several 'for' loop variations in C++ are implied to increase its applicability, power and flexibility. For example, the for loop allows us to use more than one … [Read more...]

Iteration statements allow the set of instructions to execute repeatedly till the condition doesn't turn out false. The Iteration statements in C++ and Java are, for loop, while loop and do while loop. These statements are commonly called loops. Here, the main difference between a while loop and do while loop is that while loop check condition before iteration of the loop. On the other hand, the do-while loop verifies the condition after the execution of the statements inside the … [Read more...]
