I need help with the code below. It is a C program, NOT C++.

It can only include '.h' libraries. I believe the program is in C++, but it must be a C program. Please help.

//

// main.c

// float_stack_class_c_9_29

//

//

/* Given the API for a (fixed size), floating point stack class, write the code to create a stack class (in C).

*/

#include

#include

header file to read and print the output on console

using namespace std; // Namespaces are used to organize code into logical groups and to prevent name collisions that can occur especially

//when your code base includes multiple libraries.
