C programming inquiry

this goes out to all with C experience. kinda pulling my hair over this program. have a question for all of u?

lets say I have "if ( ) else ( )"
can I have a while loop in the "if" and a do-while loop in the else part of my program. ???
thanx. is it valid?? kinda of a beginner??

u dont need the if else just use couple of loops cause if the condition fails in the first one it will go to the seconf one..that is if u got ur question right ot u van include if within the while

first off the structure is:

if ()
{}
else
{};

so you have a block of code for your condition and one for any other case. The else block is like any other block of code. So basically: yes, you can.

Just curious, what is your assignment?

c is a pain. kinda have to get used to it. It helps when I print out my script file and got through the steps in my head.

well guys....I might have to call upon u again so don't go nowhere

yes u can:

code:
do
{
   some code...
   if(a >1)
   {
     while(c<3)
     {
        printf(c);
        c = c + 1;
      }
    }
    else
    {
       printf("hello world/n");
    }
    a++
}while(a < 4);

just cuz i forgot
if I finished my "blah.c" file and i also have an input file "blah.dat"(bare w/ me)
how do I test it in Unix system
using the unix compiler cc
thanx

For your reference check out this book C Programming Language Second Edition

It's considered as the C bible

assumig: the .dat file is read within your program

put both in a nice dir

then look http://helpme.scudc.scu.edu/compilers.html <

u want to pay attention to this line:

cc prog1.c -o prog1

well I loaded my "blah.dat" file (contains the input needed for program to execute)
also loaded "blah.c" file into Unix using the ftp and put command
next I telnet into unix. I ftp'd it as and anscii file type. supposed to.
so I try to compile my "blah.c" file using cc and given parameters but it gives me errors.
prints out gibberish(guessing it supposed to do that) than it says:"
ld:
Unresolved:
acos
fabs
pow
sqrt

assuming it can't process those commands which are inside my "blah.c" file. probably need to input some sort of math directory??? helppppp??????

try adding

#include to the top of your source code, then ftp and compile again.. see what happens. That _should_ take care of swrt, pow, acos.. i do not know what fabs does though

Posted by daydreamer on Feb-03-2003 04:11:

had already done that, in the beginning of my program.
any other suggestions. oh..fyi: fabs (absolute value for floats)

see if your PATH includes the directory, where the lib's are stored

haha... i was just typing up the command incorrectly....the whole fucking time!!!
well thanx for all ya's help. thanx dritz

works like a charm now!!! woot

Posted by drizzt81 on Feb-04-2003 23:38:

ok here's a question:

why does digitalbreach ask a question.

I answer and then daydreamer tell me that he had already done that as if he had written the same program as digitalbreach???
