Hi everybody,

i´m new in programming and doing a self study in C prgramming, i dont really find it easy, i came a cross a problem which i cant solve ...can anybody explain how i go abt the following programm pls;

Read a positive integer value, and compute the following sequence: If
the number is even, halve it; if it's odd, multiply by 3 and add 1. Repeat
this process until the value is 1, printing out each value. Finally print
out how many of these operations performed?
how do i solve this problem, using the following statements;

1- If statement
2- While Statement
3- For statement

What have you tried?

Hi!!
That is The maximum cycle length problem, it is a classic!!
look it up in the net, find algorithms and try to follow using C, it is not that hard..

This is what i have tried so far,

# include <stdio.h>
# include <stdlib.h>

int main ()

{

int i = 0

for(i=0;(Xmod2==0);X/2);
for(X=0;(Xmod2!=0);x*3+1);

{
scanf ("%d",&number);
printf ("insert number %d,number\n");

At this point i cant continue....i don know if wat i am doing is right. i used mod because of the conditions that were given ....

Okay. Before you continue, write a program that reads in an integer and prints out whether that integer is even or odd.

Hi guys,
i need help. can anyone tell me how to write a program that differentiates an even number from an odd number?

Either you don't have a book on C programming or you haven't looked at one. I suggest you read one. Your code above shows you have almost no idea what you're doing. Any decent C programming book, website, etc. would help you, but only if you read it.

The modulo operator &#37; gives you the remainder from a division operation. Use it with the number two and you get 0 if the number is divisible by two, and 1 if it is not.
