Sum of integer array #3088

Write a program to collect 5 integer values from user in an integer array an

Write a program to collect 5 integer values from user in an integer array and then pass this array to a function along with its size. Return the sum of the array members from the function and print its value in the main routine.

Average value of array and members more than average #3098

Prepare an array of temperature readings of an entire week with data as
25.3, 27.0, 24.8, 26.9, 25.9, 26.4, 24.0. Now find out the average temperature of the week and then print out the readings which are more than the average temperature.

Filling integer array members based on user input and summing them #5370

Write a program to collect 5 numbers from user into a 1-D integer array. Calc

Write a program to collect 5 numbers from user into a 1-D integer array. Calculate sum of all the input numbers and print it with a suitable message.

Searching elements from one array into another array #5617

Write a program to search members of integer array 1 in array 2 and print the

Write a program to search members of integer array 1 in array 2 and print the members of array 1 that are also found in array 1. Also print the total number of members found.
For e.g. if array 1 is [12,19,23,3,2] and array 2 is [13,12,2,3,14,21],
the output would be
12 3 2
count = 3

03A #5764

( As In Exam - CBSE12A-2017 )

Write the definition of a function AddUp(int Arr[], int N) in C++, in which a

Write the definition of a function AddUp(int Arr[], int N) in C++, in which all even positions (i.e. 0,2,4,…) of the array should be added with the content of the element in the next position and odd positions (i.e. 1,3,5,…) elements should be incremented by 10.
Example: if the array Arr contains

20 30 45 10 15 25

Then the array should become

53 40 55 20 40 35

NOTE:

  • The function should only alter the content in the same array.
  • The function should not copy the altered content in another array.
  • The function should not display the altered content of the array.
  • Assuming, the Number of elements in the array are Even.

03A #5871

( As In Exam - CBSE12D-2015 )

Write the definition of a function Alter(int A[], int N) in C++, which should

Write the definition of a function Alter(int A[], int N) in C++, which should change all the multiples of 5 in the array to 5 and rest of the elements as 0. For example, if an array of 10 integers is as follows:

A[0] A[1] A[2] A[3] A[4] A[5] A[6] A[7] A[8] A[9]
55 43 20 16 39 90 83 40 48 25

After executing the function, the array content should be changed as follow:

A[0] A[1] A[2] A[3] A[4] A[5] A[6] A[7] A[8] A[9]
5 0 5 0 0 5 0 5 0 5

03A-2015 #5957

( As In Exam - CBSE12A-2015 )

Write the definition of a function Change(int P[], int N) in C++, which shoul

Write the definition of a function Change(int P[], int N) in C++, which should change all the multiples of 10 in the array to 10 and rest of the elements as 1. For example, if an array of 10 integers is as follows:

P[0] P[1] P[2] P[3] P[4] P[5] P[6] P[7] P[8] P[9]
100 43 20 56 32 91 80 40 45 21

After executing the function, the array content should be changed as follows:

P[0] P[1] P[2] P[3] P[4] P[5] P[6] P[7] P[8] P[9]
10 1 10 1 1 1 10 10 1 1

Find and write the output of the following C++ program code:
Note: Assume all required header files are already being included in the program .

void main()
{
  int A[]={10,12,15,17,20,30};
  for(int i = 0; i<6; i++)
  {
    if(A[i]%2==0)
    A[i] /= 2;
    else if(A[i]%3==0)
    A[i] /= 3;
    if(A[i]%5==0)
    A[i] /= 5;
  }
  for(i = 0; i<6; i++)
  cout<<A[i]<<"#";
}

( As In Exam - CBSE12D-2017 )

Write the definition of a function Reverse(int Arr[], int N) in C++, which sh

Write the definition of a function Reverse(int Arr[], int N) in C++, which should reverse the entire content of the array Arr having N elements, without using any other array.
Example: if the array Arr contains

13 10 15 20 5

Then the array should become

5 20 15 10 13

NOTE:
-The function should only rearrange the content of the array.
-The function should not copy the reversed content in another array.
-The function should not display the content of the array.
