Write a program whose input is a character and a string, and whose output indicates the number of times the character appears in

Delvig [45]

Answer:

// program in java.

import java.util.*;

// class definition

class Main

{

// main method of the class

public static void main (String[] args) throws java.lang.Exception

{

try{

// object to read input

Scanner scr=new Scanner(System.in);

System.out.print("Enter the String:");

// read string from user

String str=scr.nextLine();

System.out.print("Enter the character:");

// read character

char ch=scr.next().charAt(0);

// variable to count the occurrence of character

int char_count=0;

for(int i=0;i<str.length();i++)

{

// find the character i string

if(ch==str.charAt(i))

// increase the count

char_count++;

}

// print the count

System.out.println("count of "+ch+" in the String is:"+char_count);

}catch(Exception ex){

return;}

}

Explanation:

Read a string from user and assign it to variable "str".Then read a character to and assign it to variable "ch".Then Declare a variable "char_count" to count the occurrence of character in the string.Find the count of character in the string. Here upper case character is different than lower case.

Output:

Enter the String:Monday

Enter the character:n

count of n in the String is:1

Enter the String:Nobody

Enter the character:n

count of n in the String is:0

Write an abstract data type for a queue in Java whose elements are generic elements of type T that have an associated integer pr

Nimfa-mama [501]

Answer:

See explaination

Explanation:

#include<iostream>

const int MAX=20;

class dque

{

private:

int arr[MAX];

int front,rear;

public:

dque();

void addqatbeg(char item);

void addqatend(char item);

int delqatbeg();

int delqatend();

void display();

int count();

};

dque::dque()

{

front=rear=-1;

for(int i=0;i<MAX;i++)

arr[i]=0;

}

void dque::addqatbeg(int item)

{

if(front==0&&rear==MAX-1){cout<<"\nDeque is full"<<endl;return;}

if(front==-1){front=rear=0;arr[front]=item;return;}

if(rear!=MAX-1)

{int c=count();int k=rear+1;

for(int i=1;i<=c;i++){arr[k]==arr[k-1];k--;}

arr[k]=item;front=k;rear++;

}

else{front--;arr[front]=item;}
