i think i also have to correct my main() . Am i right ( mind the bold )



.....
steps1 = 0;
gdc1 = gcdrecurs(a1,a2,&steps1);
printf("the gdc is %d and %d steps were needed using...

i'n not sure i get what you mean .

steps1 points to an int that is initialised to zero

steps1=0 in function main

i

you meant what it expects in steps1 right ?


Well steps1 is supposed to count how many times the function is called ( by it self + 1 ) . So it should be an int passed by reference in order not...

sorry my mistake

i think it shoud expect an int since the final outcome should be a greatest common divisor

Thanks for replying

I have one more question for the first function



int gcdrecurs(int m,int n,int *steps1 )
{
int temp , r ;

Hi everyone

I have to write a c program that calculates the greatest common divisor of two positive numbers , using the euclides algorithm . I have to implement two functions , one that works...

thanks again for all the help!

Both those solutions though would be too much for my level . Considering that i'm a newbie , i would say that the answer is probably that the mistake the function...

no it's not .Its i<5 not i<=5

laser i'm missing your point !I'm a newbie remember ? :-)

I see your point Kbriggs .seems like a stupid exercise though no ? I mean how would this function not be wrong ? What would you change

laserlight , do you mean why is recursion used in this case? I don;t know

kbriggs i guess it is incremented after f calling and that's probably the reason it is indefinate. but how should it be?

laser , f is the name in both cases , so it is a reccuring function , so ? Ican't get any further

kbriggs the value is 1 isn't it ? , but that's not very helpful

KBriggs , no , it is an idefinat loop , i run it with dev++ and it prints n f() many many times till the execution window closes

laser , i agree that the comment is the key , but what would be a...

tab thanks for replying.

In order to see logical errors , there should be something asked like "this function is supposed to do "this" ..." , but there isn't .

Hello everyone

i 'm a newbie in c and i have this exercise :

What the error in the following function ?


...

ok guys i get your point

so what if i change it a bit :

( 4>3 ) && ( x=2 )

would that be true ?

Meaning , if the very next line of code is
