Function overloading in cpp

Function overloading


 C++ program for function overloading.Function overloading means two or more functions can have the same name but either the number of arguments or the data type of arguments has to be different. Return type has no role because the function will return a value when it is called and at compile time compiler will not be able to determine which function to call.
Function overloading is also known as compile time polymorphism.

#include <iostream>
using namespace std;

 void display(int);
void display(float);
void display(int, float);

 int main() {

     int a = 5;
    float b = 5.5;

     display(a);
    display(b);
    display(a, b);

     return 0;
}

 void display(int x) {
    cout << "Integer number: " << x << endl;
}

 void display(float x) {
    cout << "Float number: " << x << endl;
}

 void display(int x1, float x2) {
    cout << "Integer number: " << x1;
    cout << " \nfloat number:" << x2;
}
output:
Integer number: 5
Float number: 5.5
Integer number: 5
float number:5.5
Process returned 0 (0x0)   execution time : 0.300 s

C program that contains a string XOR each character in this string with 0 ,127

Write a C program that contains a string (char pointer) with a value \Hello World’. The program should XOR each character in this string with 0 and displays the result. Program: #include<stdlib.h> main() { char str[]="Hello World"; char str1[11]; int i,len; len=strlen(str); for(i=0;i<len;i++) { str1[i]=str[i]^0; printf("%c",str1[i]); } printf("\n"); } Q.2 Write a C program that contains a string (char pointer) with a value \Hello World’. The program should AND or and XOR each character in this string with 127 and display the result.

Queue in Data Structure(DS)

Queue Queues are data structures that follow the First In First Out (FIFO) i.e. the first element that is added to the queue is the first one to be removed. Elements are always added to the back(rear) and removed from the front. Think of it as  a line of people waiting for a bus. The person who is at the beginning of the line is the first one to enter the bus.   Basic features of Queue Like a stack, the queue is also an ordered list of elements of similar data types. A queue is a FIFO( First in First Out ) structure. Once a new element is inserted into the Queue, all the elements inserted before the new element in the queue  must be removed, to remove the new element. In a simple queue, there is a disadvantage after deleting element we cannot insert the element in the queue because of insertion  is possible from the rear but deletion is performed from the front.                                           insertion                                     ------------------
