Hi!
I'm trying to get ONLY "+628987654321" (without quotes) from sequence string below

    lcd_out(2,1,res);
     }
}
}

the code above gives me only "+" as the first occurrence character after string compare is match,
I want to get "+628987654321" complete string.
anyone here can share me the knowledge?
thanks.

And actually I have implicit conversion of INT to PTR issue in

lcd_out(2,1,res);

use strstr

Hi nikhilele!
thanks for the reply, I tried it but still gives me implicit issue on the message list when I compile the code.

 

[nikhilele]

you want phone no correct,
for that use
char *mob_no
mob_no = strstr(output,"+");
now try to print the mob_no upto n-1 char it will give your no

lcd_out(x,y,mob_no);

ups I forgot to close this thread, thanks to you nikhilele, you helped me. here I post the code
