Problem with string declaration!

[toktam]

Hi everyone

I want to pass a temp_string from a function to another function so I declared it as char*
but when I did this:

char* tmp_string;
assert(tmp_string=malloc(((MAXCHARS)*sizeof(char)) )!=NULL);
tmp_string=strtok(string,"|");
return tmp_string;

I got segmentation fault,How can I declare it?

Another question ;)
when we declare a string as char*,how can we copy a string to it?

HI,
Check whether the variable string (tmp_string=strtok(string,"|");) has a proper memory to it or it is not NULL.
You can copy a value to char* using strcpy function.
First get a hold of the string functions, then u can figure out the mistake u are doing.(Use this link)
