# C++ Exercises: Calculate the volume of a sphere

## C++ Basic: Exercise-14 with Solution

Write a C++ program that calculates the volume of a sphere.

Pictorial Presentation: Sample Solution:

C++ Code :

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

int main()
{
float volsp;
cout << "\n\n Calculate the volume of a sphere :\n";
cout << "---------------------------------------\n";
cout<<" Input the radius of a sphere : ";
cout<<" The volume of a sphere is : "<< volsp << endl;
cout << endl;
return 0;
}
``````

Sample Output:

``` Calculate the volume of a sphere :
---------------------------------------
Input the radius of a sphere : 6
The volume of a sphere is : 904.32
```

## C++ Programming: Tips of the Day

Why is there no std::stou?

The most pat answer would be that the C library has no corresponding "strtou", and the C++11 string functions are all just thinly veiled wrappers around the C library functions: The std::sto* functions mirror strto*, and the std::to_string functions use sprintf.
