C program C language , not c++

For this program, consider the following pseudocode algorithm for checking if a particular positive integer satises the collatz conjecture:

Algorithm 1 Collatz conjecture checker.

termi n a ti o n ( n ) { // prec o n di ti o n : n is any integ e r

while n not equal 1 do {

if even ( n )

then n := n/2

else n := 3n+1 }

output ( n ) // postcondition : n=1 }

Write a C program to implement the algorithm as a function called termination that is called from main.

Call termination from main on an input integer given by the user.

Count and display how many iterations are executed for the input.
