Array

Chapter: 16

Module – 3: Programming in C++

INTEXT QUESTIONS 16.1 

1. Write a statement that defines one dimensional array called student of type int that holds 5 data elements. 

Ans: int student [5];.

2. In the following array declarations find the number of elements in each array and total no. of bytes required to store each array.

(a) int A [ 20 ]; 

Ans: Number of elements – 20 Total number of bytes – 40.

(b) char z [ 18 ] ;

Ans: Number of elements – 18 Total number of bytes – 18.

3. What will be the output of the following programs?

(a) # include < iostream.h > 

void main ( ) 

{

      int a [ 5 ], t ; 

      for (i= 0; i < 5; i ++ ) 

      a [i] = 5 * i; 

      for (i = 0; i < 5; i ++) 

      cout << a [ i ]; 
}

Ans:  0 5 10 15 20.

(b) # include < iostream.h > 

      void main ( ) 

     { 

        char title [ ] = “Computer”; 

        for ( int i = 0; title [ i ]; i ++) 

        cout << “\n” << (title + i); 
}

Ans: Computer
omputer
mputer
puter
uter
ter
er
r

INTEXT QUESTIONS 16.2 

1. Define a two dimensional array A having 2 rows, 3 columns and stores int data type. 

Ans: int A [ 2 ] [ 3 ];.

2. Consider the following array declarations. Find the number of elements in each array and total number. of bytes required by each array. 

(a) int x [ 5 ] [ 10 ]; 

Ans: Number of elements – 50 Total number of bytes – 100.

(b) long y [ 5 ] [ 10 ];

Ans: Number of elements – 50 Total number of bytes – 200.

TERMINAL EXERCISE 

1. What is the need of an array? 

Ans: An array is used to store multiple values of the same data type in a single variable. It makes data handling easier, saves memory, and helps in writing clear and efficient programs.

2. What do you mean by searching? 

Ans: Searching is the process of finding an element within the array list.

3. What do you mean by sorting? 

Ans: Sorting is a method to arrange the list either in ascending or descending order.

4. Write a program that will read 20 float values in a one dimensional array and find out the following:

(i) Number of values greater than zero. 

Ans: #include <stdio.h>

int main() {
    float a[20];
    int i, c = 0;

    for (i = 0; i < 20; i++)
        scanf("%f", &a[i]);

    for (i = 0; i < 20; i++)
        if (a[i] > 0) c++;

    printf("%d", c);
    return 0;
}
