converting string to integer, for further use

before you flame me, i´ve tried both strtol AND atoi and they dont work.

i´m trying to convert a string to and intger. when i display the string on screen, it is perfect (122). but when i make a folder with the contents of this string, it comes out really wierd.

i tried strtol and atoi but it doesnt make a difference.

my attempt:

Code:

---

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

char streaminput[BUFSIZ] = "#RAWWAASFRAMEA,COM1,9,68.0,SATTIME,1263,126458.000,00000000,58e4,1522,22,122,62,5663456345dba43623443efdaef3245345fea32534562663462323c000,22*d04567cde";       
char wasteitems[BUFSIZ] = "#RAWWAASFRAMEA SATTIME COM ; , * .";

//output array of filtering stage

char *filteredstream;
char *firstfilter;
char *secondfilter;
char *thirdfilter;
char *fourthfilter;
char *decodweek;
char *decodtime;
char *seventhfilter;
char *eigthfilter;
char *ninthfilter;
char *tenthfilter;
char *eleventhfilter;
char *decodPRN;
char *decodmsgtype;
char *decodmsg;
char *fifteenthfilter;
char *decodPRC;
int intPRN;

char decoddate[9] = "20 06 05";  // ONLY FOR TEST!!!

int main()

{
printf( "remaining data:\n" );

firstfilter = strtok( streaminput, wasteitems );

//****************Opens a file in the temp folder to write temp array to************//

secondfilter = strtok( NULL, wasteitems );
thirdfilter = strtok( NULL, wasteitems );
fourthfilter = strtok( NULL, wasteitems );
decodweek = strtok( NULL, wasteitems );
printf( "\n decodweek: %s", decodweek );
decodtime = strtok( NULL, wasteitems );
printf( "\n decodtime: %s", decodtime );
seventhfilter = strtok( NULL, wasteitems );
eigthfilter = strtok( NULL, wasteitems );
ninthfilter = strtok( NULL, wasteitems );
tenthfilter = strtok( NULL, wasteitems );
eleventhfilter = strtok( NULL, wasteitems );
decodPRN = strtok( NULL, wasteitems );
printf( "\n decodPRN: %s", decodPRN );
decodmsgtype = strtok( NULL, wasteitems );
printf( "\n decodmsgtype: %s", decodmsgtype );
decodmsg = strtok( NULL, wasteitems );
printf( "\n decodmsg: %s", decodmsg );
fifteenthfilter = strtok( NULL, wasteitems );
decodPRC = strtok( NULL, wasteitems );
printf( "\n decodPRC: %s \n\n", decodPRC );

//intPRN = atoi(decodPRN);
intPRN = strtol(decodPRN,NULL, 100);

printf("intPRN: %3d, intPRN");
 }

Why are you using base 100? Also, strtol and atoi aren't your problems. Here, I'll prove it to you:

Code:

---

#include <stdio.h>
#include <stdlib.h>
int main( void )
{
    char foo[] = "1234";
    int bar;

    bar = atoi( foo );
    printf("bar is %d\n", bar );

    return 0;
}

---

Finally, please learn how to use printf, and turn on your compiler's warnings and listen to them!

Code:

---

printf("intPRN: %3d, intPRN");

---

WRONG!

Code:

---

printf("intPRN: %3d", intPRN);

---

This isn't the first time I've showed you that you weren't using printf right.


Quzah.

ok, that was an error on the last line.

if you lok at the previous part of the code, i think its pretty obvious i know how to use it.........
