C program Make sure it runs please

Imagine a system where the Sign, Exponent and Fraction bits are 1, 5, and 10 bits in size respectively (in total 16 bits). Write down the bits representation for the number 6.5 used in IEEE Floating-point Representation (Normalized value). What would the value of the representation in short int data type. What is the floating point equivalent for the following bits representation in Normalized form. 1100000001001010 Hand simulation is needed to verify your result. (Bonus Points) According to you, what is the maximum and minimum floating point value can be represented using this 16 bits representation. Please prove your claim.
