Chapter 7 of Class 10 Computer Applications delves into the fascinating realm of Arrays. Arrays are fundamental data structures that allow the storage of multiple elements of the same type under a single variable name. This chapter explores the concept of arrays, their declaration, initialization, manipulation, and various operations that can be performed on them. In this chapter, students will unravel the power of arrays, learning how to harness their capabilities to solve problems and manipulate data effectively within computer programs. Solving ICSE class 10 computer important questions of Arrays will help students understand the concepts better.
Arrays are fundamental data structures in programming that enable the storage of multiple elements of the same data type under a single variable name. They act as containers, allowing organized storage and easy access to a collection of elements. Solving important questions for class 10 ICSE essential for a comprehensive understanding and successful examination preparation. Explore further with oswal.io for ICSE class 10 important questions 2023-24 of Arrays to strengthen your knowledge in these fundamental areas of computer.
Ans. (a) Private
Explanation:
In a Binary search the middle index is found and the array is divided into two halves to search for an element.
Ans. (b) 202
Explanation:
marr[-1+2] is marr[1] which is the element at index 1 , that is 202.
Explanation:
For array, length is a property so we use char.length to get the length of a char array and for a string object, length is a function so we use str.length().
Explanation:
a[4] will occupy 2 * 4 = 8 Bytes.
p[4] will occupy 4 * 4 = 16 Bytes.
Explanation:
import java.util.*;
class Student
{
public static void main(String args[])
{
Scanner s = new Scanner(System.in);
String[] name = new String[35];
int[] percent = new int[35];
System.out.println(“Please enter name and percentage of 35 students”);
for(int i = 0; i < 35; i++)
{
name[i] = s1.nextLine();
percent[i] = s1.nextInt()
}
int index;
int small, temppercent;
String tempname;
for(int a = 0; a < 34; a++)
{
for (int b = 0; b < 34; b++)
{
if (percent[b] > percent[b+1])
{
temppercent = percent[b];
percent[b] = percent[b+1];
percent[b+1] = temppercent;
tempname = name[b];
name[b] = name[b+1];
name[b+1] = tempname;
}
}
}
int pos = 1;
System.out.println(“First 10 toppers of the class”);
for(int i = 34; i >= 25; i –)
{
System.out.println(“Position:”+pos);
System.out.println(“Name:”+ name[i]);
System.out.println(“Percentage marks:”+ percent[i]);
pos++;
}
}
}
In conclusion, Chapter 7 on Arrays in Class 10 Computer Applications lays the foundation for understanding and leveraging one of the most essential data structures in programming. Through comprehensive exploration, students have uncovered the significance of arrays, learning how to declare, initialize, manipulate, and utilize these structures to efficiently manage collections of data. If you are looking to further practice and enhance your understanding of the concepts discussed in the chapter, oswal.io provides a comprehensive set of class 10 Arrays important questions and answers for understanding the concept in a better way.
Ans: An array in programming is a data structure that allows storing multiple elements of the same data type under a single variable name. It provides a systematic way to organize and access a collection of data elements.
Ans: The index in arrays represents the position of an element within the array. It starts from 0 in many programming languages, enabling access to specific elements by their unique position.
Ans: In most programming languages, the size of a traditional array is fixed upon declaration and cannot be changed. However, some languages offer dynamic arrays or resizable arrays that can be expanded or shrunk during program execution.
Ans: Arrays support various operations, including adding or updating elements, accessing elements using indexes, searching for specific values, sorting elements, and traversing the entire array to perform specific tasks on each element.
Ans: Yes, arrays typically store elements of the same data type. For instance, an array of integers will hold only integer values, and an array of strings will contain only strings.
