The sprintf() stands for “string print.” The sprintf() function does not print the output on the console screen. It transfers the data to the buffer. It returns the total number of characters present in the string.

Syntax

int sprintf ( char * str, const char * format, … );

When a function calls itself, and this process is known as recursion. The function that calls itself is known as a recursive function.

Recursive function comes in two phases:

1)Winding phase
2)Unwinding phase

Winding phase: When the recursive function calls itself, and this phase ends when the condition is reached.

Unwinding phase: Unwinding…[Read more]

A virtual function is a member function in the base class that you redefine in a derived class. It is declared using the virtual keyword.

Example-

class base{
public:
virtual void fun(){

}
};
A pure virtual function is a function that has no implementation and is declared by assigning 0. It has no body.

Example-

class base{
public:
v…[Read more]

A constructor is automatically called when an object is first created. Similarly when an object is destroyed a function called destructor automatically gets called. A destructor has the same name as the constructor (which is the same as the class name) but is preceded by a tilde.

Example:

class A{
private:
int val;
public:
A(int x){…[Read more]

The constructor is a member function that is executed automatically whenever an object is created. Constructors have the same name as the class of which they are members so that compiler knows that the member function is a constructor. And no return type is used for constructors.

Example:

class A{
private:
int val;
public:
A(int x){…[Read more]

Operator Overloading is a very essential element to perform the operations on user-defined data types. By operator overloading we can modify the default meaning to the operators like +, -, *, /, <=, etc.

For example –

The following code is for adding two complex number using operator overloading-

class complex{
private:
float r, i;
public:…[Read more]

OOP refers to object-oriented programming. It is a programming model that focuses on creating classes and objects. Contrary to structural programming, OOP allows you to write concise codes by reusing the codes and creating the instance of the objects.

The ribbon is used as a substitute for the toolbars and menu bar in the earlier versions of Microsoft Office. In the Ribbon, toolbar buttons and file menu items were grouped as per the functionality. It made these functions easily accessible on the main interface, with most primarily utilized buttons being displayed instantly.

The cell address of an Excel sheet refers to the address that is obtained by the combination of the Row number and the Column alphabet. Each cell of an MS Excel sheet will have a distinct cell address.

#include <stdio.h>
int main() {

int number1, number2, sum;
printf(“Enter two integers: “);
scanf(“%d %d”, &number1, &number2);
sum = number1 + number2;
printf(“%d + %d = %d”, number1, number2, sum);
return 0;
}
