C programming language allows jumping from one statement to another. It also supports break, continue, return and go to jump statements.breakIt is a keyword which is used to terminate the loop (or) exit from the block.The control jumps to next statement after the loop (or) block.break is used with for, while, do-while and switch statement.When break is used in nested loops then, only the innermost loop is terminated.The syntax for break statement is as follows −ExampleFollowing is the C program for break statement − Live Demo#include main( ){    int i;    for (i=1; i

In C programming language, control statements are used to repeat a set of statements, while conditional statements are used for decision-making. These decision-making statements are also used to determine one or more conditions that decides whether a set of statements should be executed. They are as follows − for loop while loop do-while loop For loop and while loop, the condition specifies the number of times the loop can be executed. The "for loop" The for loop is an entry-controlled loop that executes statements until the ... Read More

In object oriented programming, both constructor and destructor are the member functions of a class having the same name as the class. A constructor helps in initialization of an object, i.e., it allocates memory to an object. On the other hand, a destructor deletes the created constructor when it is of no use which means it deallocates the memory of an object. In this article, we will discuss the important differences between constructors and destructors. Let's start with some basic concepts of constructors and destructors. What is a Constructor? A constructor is a member function of a class that initializes ... Read More

In this post, we will understand the difference between local and global variables.Local variableIt is generally declared inside a function.If it isn’t initialized, a garbage value is stored inside it.It is created when the function begins its execution.It is lost when the function is terminated.Data sharing is not possible since the local variable/data can be accessed by a single function.Parameters need to be passed to local variables so that they can access the value in the function.It is stored on a stack, unless mentioned otherwise.They can be accessed using statement inside the function where they are declared.When the changes are ...

In this post, we will understand the difference between static binding and dynamic binding.Static BindingIt is resolved at compile time.It uses type of the class and fields.It uses private, final, and static methods and variables.Example: OverloadingDynamic BindingIt is resolved during run time.Virtual methods use this technique.It uses objects to resolve the binding.Example: Method overriding.

In this post, we will understand the difference between type casting and type conversion.Type castingA data type is converted to another data type using the casting operator by the developer.It can be applied to any compatible data types and incompatible data types.The casting operator is required to cast a data type to another type.The destination data type could be smaller than the source data type.It happens during the program design.It is also known as narrowing conversion since the destination data type may be smaller than the source data type.It is generally used in coding and competitive programming.It is efficient.It is ...

In this post, we will understand the difference between break and continue statements.breakIt is used to terminate the enclosing loop like while, do-while, for, or switch statement where it is declared.It resumes control over the program until the end of the loop.It also helps with the flow of control outside the loop.It is used with ‘switch’ and ‘label’ since it is compatible.Following is the flowchart of break statement −continueIt helps skip the remaining part of the loop.It continues to execute the next iteration.It causes early execution of the next iteration of the enclosing loop.It can’t be used with ‘switch’ and ...

In this post, we will understand the difference between one dimensional array and two dimensional array.One dimensional arrayIt helps store a single list of elements that are similar data type.The total bytes is calculates as the product of the datatype of variable array and the size of the array.C++ declarationtype variable_name[ size ];Java declarationtype variable_name [ ]; variable_name = new type[size];int [ ] a = new int [10];Two-Dimensional arrayIt helps store 'list of lists' or 'array of arrays' or 'array of one dimensional arrays', i.e nested arrays.The total bytes is equivalent to product of datatype of variable array and size ...

In this post, we will understand the difference between virtual and pure virtual functions.Virtual FunctionIt has its own definition inside the class.The base class can override a virtual function.It doesn’t have a derived class.Declarationvirtual funct_name(parameter_list) {. . . . .};Pure Virtual FunctionIt doesn’t have a definition.If a class has at least one virtual function, it can be declared abstract.The derived class has to override the pure virtual function to use it.A pure virtual function is specified by placing "= 0" in its declarationDeclarationvirtual funct_name(parameter_list)=0;Following is an example −Exampleclass Box {    public:    // pure virtual function    virtual double ...

In this post, we will understand the difference between the ‘while’ loop and the ‘do-while’ loop.while conditionThe controlling condition here appears at the beginning of the loop.The iterations do not occur if the condition at the first iteration results in False.It is also known as an entry-controlled loopThere is no condition at the end of the loop.It doesn’t need to execute at least one.Examplewhile ( condition){ statements; //body of loop }Following is the flowchart of while loop −do-while conditionThe controlling condition is present at the end of the loop.The condition is executed at least ...
