floating point representation

In this exercises you will familiarize with basic proprerties of floating point represantation

1. count the number of floating points between two of them
2. extract the exponent of a float

3. produce NaN and inf, verify the value of their exponent

   #include<iostream>
   #include<iomanip>
   #include<cmath>
   #include<limits>
   #include<cstdio>
   #include<cstring>
      
   int count(float x, float e) {
          // fill in
   } 
   int exponent(float x) {
          // fill in
   }
   
   int main() {
   
     std::cout << count(.1f,1.f) << std::endl;
     std::cout << count(2.f,3.f) << std::endl;
     return 0;
   
   }
