(Attempt any four questions.)
Question 2:
Define a class to declare an integer array of size n and accept the elements into the array. Search for an element input by the user using linear search technique, display the element if it is found, otherwise display the message “NO SUCH ELEMENT.
Answer :
#include<iostream>
using namespace std;
class dec {
public:
int a[];
dec(int b[],int n) {
for(int i=0,i<n,i++)
a[i]=b[i];
}
void search(int x) {
for(int i : a) {
if (i==x) {
cout << i;
break;
}
}
}
};
int main() {
int arr[3]={1,2,3};
dec obj(arr,3);
obj.search(2);
}
Question 3 :
Define a class to declare a character array of size ten, accept the character into the array and perform the following:
• Count the number of uppercase letters in the array and print.
• Count the number of vowels in the array and print.
Answer :
To count the number of uppercase letters in the array and print.
/ Java Program to Count Number of Vowels// in a String in a iterative wayimport java.io.*;public class vowel { public static void main(String[] args) throws IOException { String str = "GeeksForGeeks"; str = str.toLowerCase(); int count = 0; for (int i = 0; i < str.length(); i++) { // check if char[i] is vowel if (str.charAt(i) == 'a' || str.charAt(i) == 'e' || str.charAt(i) == 'i' || str.charAt(i) == 'o' || str.charAt(i) == 'u') { // count increments if there is vowel in // char[i] count++; } } // display total count of vowels in string System.out.println( "Total no of vowels in string are: " + count); }}Question 4 :
Define a class to declare an array of size 20 of double datatype, accept the elements into the array and perform the following:
• Calculate and print the sum of all the elements.
• Calculate and print the highest value of the array.
Answer :
To Calculate and print the sum of all the elements.
/* C++ Program to find sum of elementsin a given array */#include <bits/stdc++.h>using namespace std;// function to return sum of elements// in an array of size nint sum(int arr[], int n){ int sum = 0; // initialize sum // Iterate through all elements // and add them to sum for (int i = 0; i < n; i++) sum += arr[i]; return sum;}// Driver codeint main(){ int arr[] = {12, 3, 4, 15}; int n = sizeof(arr) / sizeof(arr[0]); cout << "Sum of given array is " << sum(arr, n); return 0;}// C++ program to find maximum// in arr[] of size n#include <bits/stdc++.h>using namespace std;int largest(int arr[], int n){ int i; // Initialize maximum element int max = arr[0]; // Traverse array elements // from second and compare // every element with current max for (i = 1; i < n; i++) if (arr[i] > max) max = arr[i]; return max;}// Driver Codeint main(){ int arr[] = {10, 324, 45, 90, 9808}; int n = sizeof(arr) / sizeof(arr[0]); cout << "Largest in given array is " << largest(arr, n); return 0;Define a class to accept two strings, convert them into uppercase, check and display whether two strings are equal or not, if the two strings are not equal, print the string with the highest length or print the message both the strings are of equal length.
Answer :
// Function to compare two strings ignoring their casesbool equalIgnoreCase(string str1, string str2){ int i = 0; // Convert to uppercase // using transform() function and ::toupper in STL transform(str1.begin(), str1.end(), str1.begin(), ::toupper); transform(str2.begin(), str2.end(), str2.begin(), ::toupper); // Comparing both using inbuilt function int x = str1.compare(str2); // if strings are equal, // return true otherwise false if (x != 0) return false; else return true;}// Function to print the same or not same// if strings are equal or not equalvoid equalIgnoreCaseUtil(string str1, string str2){ bool res = equalIgnoreCase(str1, str2); if (res == true) cout << "Same" << endl; else cout << "Not Same" << endl;}// Driver Codeint main(){ string str1, str2; str1 = "Geeks"; str2 = "geeks"; equalIgnoreCaseUtil(str1, str2); str1 = "Geek"; str2 = "geeksforgeeks"; equalIgnoreCaseUtil(str1, str2); return 0;}Question 6 :
Define a class to accept a string, convert it into lowercase and check whether the string is a palindrome or not. A palindrome is a word which reads the same backward as forward.
Example:
madam, racecar etc.
Answer :
public class PalindromeString
{
public static void main(String[] args) {
String string = “Kayak”;
boolean flag = true;
//Converts the given string into lowercase
string = string.toLowerCase();
//Iterate the string forward and backward, compare one character at a time
//till middle of the string is reached
for(int i = 0; i < string.length()/2; i++){
if(string.charAt(i) != string.charAt(string.length()-i-1)){
flag = false;
break;
}
}
if(flag)
System.out.println(“Given string is palindrome”);
else
System.out.println(“Given string is not a palindrome”);
}
}
Question 7:
Define a class to accept and store 10 strings into the array and print the strings with even number of characters.
Answer :
public class Main
{
public static void main(String[] args) {
String[] strs = new String[10];
java.util.Scanner sc = new java.util.Scanner(System.in);
for(int i = 0; i < 10; i++){
System.out.print(“Enter string ” + (i+1) + “:”);
strs[i] = sc.nextLine();
}
System.out.println(“The strigs with even number of characters is”);
for(int i = 0; i < strs.length;i++){
if(strs[i].length() % 2 == 0){
System.out.println(strs[i]);
}
}
}
}
