nice fractions?


the only thing i want to assume is float range and positive values...

i know this has been mentioned over and over (and over) again in this forum but i would like to ask specifically on a function i've been playing around:



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

By the time i was in the middle of trying post #4, i "copy paste" #6 and worked just fine. my deep thanks to all of you guys, you're great.

ps. i just found #6 initialization in "pointers on c"...

agreed but how do i initialize it? i tried


char *index[INDEXSIZE];


inside the struct body while trying to initialize outside with this:


st1.index[]={"debug","itterations","population",

hi there!

here's my question. i've been struggling about 2 hours with this but haven't figured it out yet.

suppose we have this string array



char index...

thanks a lot i just learned that if i want to access an already allocated pointer with another i don't have to allocate it too :eek:
pretty noob i think

thank you very much... i appreciate your...

this is a snaphot of the code.i hope it helps because i can't find a point where the pointer is dereferenced.


int **gene_pricing(int run_mode,int no_of_vehicles,int gene_dim,int *gene,
int...

if i don't free in main the code seems to leak exactly the double amount of bytes. doesn't this mean that the memory allocated in int **f() is never freed? but i can't free it before i return it.

i did as you said. it really works internally but when i free it from main i still get leaks.
any suggestions? i would post code but its pretty huge. i'll try to cut things out and maybe post it...

i want to initialise,return and free a variable length 2-d array...
suppose i do this:



int **f(some input){

int **p;
p=malloc(dim_1*sizeof(int *));

if don't put close() the above are running cool. prob_type can be LIN_KERN or LP. it is strange but it really works causing the execl() to choose right.

what is 1 inside the close() argument???

when applying the above in my code and every executable once, the second produces funny results...



void tsp_sol_call(char *exec_path,char...

i am on linux so i think i can get round this.

thanx!!!

perhaps into a file or something??? if it is a file it would cost too much because these lines of code run hundreds of times solving a genetic. on the other hand you can't make an omelete if you...

:rolleyes: Another question on that. Is there any way to suppress all screen output produced by the executables while runtime??? supposed the execs themselves do not provide this option...

OMG it IS the problem... thanx i didn't really noticed.

many thanx it works fine...

it just slipped away ignore it.it works fine with or without it



nope it's not perror
here's the output


panos@mate:/media/hda7/source_vrp$ ./project

we have 2 executables being called exactly the same way:
concorde : user@host:~/vrp/concorde/TSP$ ./concorde -o tsp_out input_file
linkern : user@host:~/vrp/concorde/LINKERN$ ./linkern -o ...

thanks alot!!!

is there any way to retrieve the pointer value externally while being able to free the memory it allocates? i guess that when the function returns all the allocated space will be unreachable to...

i can guess that there will be problems if i free(p) and try to return p with int *f() ???

supposed we have a this



int func(){
int *p;

p=malloc(some,sizeof some);

return something_else;

thanks a lot!!! :)

another problem too. when i compile the above source i get the following messages:

when compiling lin_call.c :

lin_call.c: In function ‘lin_call’:
lin_call.c:6: warning: incompatible implicit...

as if it would be the first thing they have ommited...

ubuntu doesn't even have the basic gcc packages for gcc on first install. :(
