Instructions

Write a program to test the functions described in Exercises 11 and _14_ of this chapter.

Instructions for Exercise 11 and Exercise 14 have been posted below for your convenience.

EXERCISE 11

Write the definition of a function that takes as input a char value, and returns true if the character is a whitespace character; otherwise it returns false.

If the character is a whitespace character ouput the following message: The character you entered is a whitespace character, othersise output: The character you eneted is not a whitespace character

EXERCISE 14

Write the definition of a function that takes as input three numbers. The function returns trueif the floor of the product of the first two numbers equals the floor of the third number; otherwise it returns false. (Assume that the three numbers are of type double.) Output the appropriate message:The product of the first two numbers is not equal to the floor of the third number

or

The product of the first two numbers is equal to the floor of the third number

Answer 1

Explanation::

• Code in C++ is given below.
• Please read comments for better understanding of the code.
• Screenshots of the code are given at the end of the code.

CODE IN C++ ::

#include<iostream>
#include<string>
#include<cmath>
using namespace std;
bool isWhiteSpace(char c);
bool floorCheck(double a,double b,double c);
int main(){
/***
* Calling function isWhiteSpace()
* A char variable named ch is declared below and
* I have used string to take input from user and then assign char at
* index 0 to char variable ch.
*/
string str;
char ch;
cout<<"PART A :: EXERCISE 11\n"<<endl;
cout<<"Enter any char ::";
getline(cin,str);
ch=str[0];
if(isWhiteSpace(ch)){
cout<<"The character you entered is a whitespace character\n"<<endl;
}else{
cout<<"The character you entered is not a whitespace character\n"<<endl;
}
cout<<"\n_______________PART A ENDS_______________\n\n"<<endl;

/***
* Calling function floorCheck()
*
* Three double values are declared named a,b and c
*/
double a,b,c;
cout<<"PART B :: EXERCISE 14\n"<<endl;
cout<<"Enter 1'st double value ::";
cin>>a;

cout<<"Enter 2'nd double value ::";
cin>>b;

cout<<"Enter 3'rd double value ::";
cin>>c;
if(floorCheck(a,b,c)){
cout<<"\nThe product of the first two numbers is equal to the floor of the third number\n"<<endl;
}else{
cout<<"\nThe product of the first two numbers is not equal to the floor of the third number\n"<<endl;
}
cout<<"_______________PART B ENDS_______________\n"<<endl;

return 0;
}
bool isWhiteSpace(char ch){
/**
* If char ch is a whitespace then ch==' ' will be true and so
* true will be returned.
* Else false will be returned.
*/
return ch==' ';
}
bool floorCheck(double a,double b,double c){
/**
* This function returns true if following condition is true.
* I.e floor(a*b) is equal to floor(c),
* else it will return false.
*/
return floor(a*b)==floor(c);
}

OUTPUT::
