Thread: This dude need someones help, bad????

Hello again,

I cant seem to get the forth root to execute properly. Eg; at int 3 the square should read 1.732050808 and the forth root should read 1.316074013. Now my squares are fine but the forth roots aren't. What is wrong in my program and how can i fix it quickly.
Thanx,

#include<stdio.h>
#include<math.h>

void prn_heading (void);
void prn_and_read_data (void);

int main()
{
prn_heading();
prn_and_read_data();
return 0;
}

void prn_heading(void)
{
printf("%3s%28s%28s%28s",
"Integer", "Square Root", "Fourth Root\n",
"--------------------------------------------------------------\n\n");
return;
}

void prn_and_read_data (void)
{
int x;
double square_root, fourth_root;

for (x = 1; x <= 100; ++x)
printf("%5d:%28.9e %28.9e\n", x = x, sqrt(x), square_root = pow(x, x));
fourth_root = square_root * square_root;
printf("%50.9e", fourth_root);
;
return;
}

Hello,
when i started the program i too could not believe it but somewhere in the code maybe...i donno.
anyway another question i had is when i ran it after compiling all the forth root numbers were exactly the same... sounds wierd huh?
can you please explain why?

If i axe x = x then it prints it onto the scree haphazardly. I tried what you said by placing it in the argument stream but on the visual C++ software that what i got.

Now my fourth root does not print with any changes, its something like 2.65 all the way down. weird huh?
I am sure my math is correct but like the old west says " i aint no math want to be player!"
just kidding... no sense to be made there!

Hello,
your close but no dice. The program when you run it should read:

integer sq rt fth rt
1 1.00000000 1.00000000
2 1.414213562 1.189207115
3 1.732050808 1.316074013
4 2.00000000 1.414213562

Thanks for trying to help me out. If you can still try i would appreciate it.
Keep pimpin'

Do you mean like this?
Because its still not working, Mr. Pimp.
Thanks anyways but if you can get it to work, please let me know, sir.
It does complie and run but the figures are way off and i am starting to wonder whoever wrote this damn book was probably way off to start with.
Thanks!
