Answer to Question #280287 in C++ for Collay

Question

3. Negative Allergy

by CodeChum Admin

Whole numbers are great, but I think we should also pay attention to decimal numbers, too.

So, how about we make a program that involves a lot of decimals?

Instructions:

Continuously ask for floating point values (decimal numbers) using the do…while() loop, sum them all up, and store the total into one variable.

The loop shall only terminate for the following reasons:

A negative decimal number is inputted (but still included in the total sum)

The total sum reaches 100.0 or more

Input

Multiple lines containing float number on each.

1.1

1.2

1.3

1.4

-1.0

Output

A line containing a float number with two decimal places.

4.00

Answer 1

#include<iostream>

using namespace std;

int main()
{
	float value;
	float sum=0;
	do
	{
		cout<<"Please, enter a float value: ";
		cin>>value;
		sum+=value;
	}while(value>=0&&sum<=100);
	cout<<"Sum of floating values is "<<sum;
}
