Question

C++ Programming

1. Write a function (header and body) that accepts an integer as an argument and returns that number squared.

2. Write the code that will fill an integer array named multiples with 10 integers from 5 to 50 that are multiples of five. (This should NOT be in the form of an initialization statement.)

3. Write the code that will display the contents of the integer array named multiples. Recall: the size of the array is 10.

4. Write the code that will display every other value (starting with the very first value) in the integer array named multiples. Recall: the size of the array is 10.

5. Write the code that takes two parallel string arrays named firstnames and lastnames and displays the first name and last name of each matching subscript with a space in between. After displaying a first and last name, start a new line.

6. Declare and initialize a two-dimensional integer array named matrix with the values below. The array should be able to hold the values as they are set up below.

1       2

10     20

100   200

7. An array named numbers has been filled with 10 integer values. Write the code that finds and displays the smallest number in the array.

8. Write the function prototype for a function named calcMarkup that accepts a float value and constant float value. The function will return a floating value.

9. A video rental store keeps DVDs on 50 racks with 10 shelves each. Each shelf holds 25 DVDs. Declare a three-dimensional array named DVDrentals large enough to represent the store's storage system.

9a. Using the same three-dimensional array from the previous problem, write the code that calculates the total number of DVDs and stores it in the variable named total.

Answer 1

1)

int squared(int num)
{
   return num*num;
}

=============================

2)  

//Declaring variables
   const int SIZE=10;
int multiples[SIZE];
for(int i=0;i<SIZE;i++)
{
   multiples[i]=5*(i+1);
   }

==================================

3)
#include <iostream>
#include <iomanip>

using namespace std;

int main() {
   //Declaring variables
   const int SIZE=10;
int multiples[SIZE];
for(int i=0;i<SIZE;i++)
{
   multiples[i]=5*(i+1);
   }
  
   for(int i=0;i<SIZE;i++)
   {
       cout<<multiples[i]<<" ";
   }
   cout<<endl;
  

  
  
   return 0;
}

============================

output:

====================================

4)
#include <iostream>
#include <iomanip>

using namespace std;

int main() {
   //Declaring variables
   const int SIZE=10;
int multiples[SIZE];
for(int i=0;i<SIZE;i++)
{
   multiples[i]=5*(i+1);
   }
  
   for(int i=0;i<SIZE;i+=2)
   {
       cout<<multiples[i]<<" ";
   }
   cout<<endl;
  

  
  
   return 0;
}

=================================

Output:

===================================

6)
#include <iostream>
#include <iomanip>

using namespace std;

int main() {
   //Declaring variables
   const int ROW=3,COL=2;
int matrix[ROW][COL]={{1,2},{10,20},{100,200}};
  
for(int i=0;i<ROW;i++)
{
   for(int j=0;j<COL;j++)
   {
       cout<<matrix[i][j]<<" ";
       }
       cout<<endl;
   }
  
  
   return 0;
}

======================================

Output:

======================================

7)

#include <iostream>
#include <iomanip>

using namespace std;

int main() {
   //Declaring variables
   const int SIZE=10;
int numbers[SIZE]={45,43,23,67,78,80,44,88,99,55};
int min=numbers[0];
for(int i=0;i<SIZE;i++)
{
if(min>numbers[i])
{
   min=numbers[i];
       }
   }
  
   cout<<"Smallest Element :"<<min<<endl;
  
  
   return 0;
}

output:

===================I will Try rest questions...Thank u
