Chapter 1, Problem 1P

Explanation of Solution

Program code:

//include the required header files

#include<iostream>

#include<cstdlib>

//use std namespace

using namespace std;

//function that takes an array

//it will generate random integers

void Random_Order(int arr[],int n)

{

    //variable for counting random integers between 1 to 52

    int count=0;

   //while loop will iterate till count will equal to 52

    while(count<n)

    {

//flag to check random number is already generated or not

        int flag=0;

        //built in function to generate random number

        int random_number=(rand()%n)+1;

//for loop for checking if random number is exist in the array or not

        for(int i=0;i<count;i++)

        {

//if number is exist in the array, make flag as 1

            if(random_number==arr[i])

            {

                //set flag as 1

                flag=1;

            }

        }

        //if flag is 0, add into array

        if(flag==0)

        {

            //add number to the array

   arr[count]=random_number;

            //increment the count by 1

            count++;

        }

    }

    //create a variable c

    int c=0;

    //print the statement

    cout<<"52 Random Numbers:\n\n";

    //displaying numbers

    //10 integers in each row

    for(int i=0;i<n;i++)

    {

        //print the values

        cout<<arr[i]<<"\t";

        //increment c by 1

        c++;

        //if the value of c is 10

        if(c==10)

        {

            //print new line

            cout<<"\n";

            //set the value c is 0

            c=0;

        }

    }

    //print new line

    cout<<"\n";

}

//main method

int main()

{

    //create an integer variable n

    int n=52;

    //create an integer array arr

    int arr[n];

    //call the method Random_Order()

    Random_Order(arr,n);

}

Explanation:

The above snippet of code is used print 52 random numbers using “rand()” function. In the code,

• Include the required header files.
• Use the “std” namespace.
• Define “Random_Order()” function.
  • Declare the required variable “count”.
  • Iterate a “while” loop.
    • Declare an integer variable “flag”.
    • Call built in function “rand()” to get the random number and save it to the variable “random_number”.
    • Iterate a “for” loop to check the number is already exist in the array.
      • If the value of “random_number” is equal to value at “arr[i]”.
        • Set the value of “flag” as “1”.
    • If the value of “flag” is “0”...
