Make a C program having four copies of sum function. Please note all the functions will have different names.

Every C function is required to pass two numbers to the function and calculate the sum of all the numbers between them (both inclusive). [10 marks]

The four functions should calculate sum using:

a.      Using for loop

b.      Using  while loop

c.      using do.. while loop

d.      Using goto loop

Please note that you need to use the same number of variables and almost the same logic in all the four loops
