I assume C:

> {
>     char text[3000];
>     ...
>     ...
>     ...

FileContent returns a char. You assign it to an array which is not proper.
If you intend it to return a char, you have to do something like:

text[0]=FileContent("temp.txt");


If you made a mistake and intend to return a char * you have either to do:


char *text;

/* ... */

text=FileContent("temp.txt");


or 


char text[3000];
char *p;

/* ... */

p=FileContent("temp.txt");

strncpy(text, p, 3000);

text[2999]='\0';
