Answer to Question #308133 in C++ for derano

Question

The purpose of this problem is to write some small functions and practice passing things around amoung functions.

1) The main function shall ask the user to enter three numbers and read the three numbers.

2) Write a function named findSum that takes three numbers as arguments and returns their sum. The main function shall call this function.

3) Write a function named findAverage that takes the sum and the number of numbers and returns the average. The main function shall call this function.

4) Write a function named findSmallest that takes the three numbers and returns the smallest value. The main function shall call this function.

5) The main function shall print the results in the following format, with two decimal positions and the decimal points aligned:

Results:
First  number   17.23
Second number    3.98
Third  number   22.32
Total           43.53
Average         14.51
Smallest         3.98
  

Test the program twice with the following two sets of numbers:

37.144  2.4144  19
 4.23   5.78     6.21
  

Answer 1

#include <iostream>
#include <string>
using namespace std;




float findSum(float number1,float number2,float number3){
	return number1+number2+number3;
}
float findAverage(float sum,float n){
	return sum/n;
}
float findSmallest(float number1,float number2,float number3){
	if (number1 < number2 && number1 < number3)
	{
		return number1;
	}
	if (number2 < number1 && number2 < number3)
	{
		return number2;
	}
	return number3;
}


int main() {


	float number1;
	float number2;
	float number3;


	cout<<"Enter number 1: ";
	cin>>number1;
	cout<<"Enter number 2: ";
	cin>>number2;
	cout<<"Enter number 3: ";
	cin>>number3;


	float total=findSum(number1,number2,number3);
	float average=findAverage(total,3);
	float smallest=findSmallest(number1,number2,number3);


	cout<<"\nFirst  number   " <<number1<<"\n";
	cout<<"Second number   " <<number2<<"\n";
	cout<<"Third  number   " <<number3<<"\n";
	cout<<"Total           " <<total<<"\n";
	cout<<"Average         " <<average<<"\n";
	cout<<"Smallest        " <<smallest<<"\n";




	system("pause");


	return 0;
}
