'C' code

please would anyone consider helping me write code? i need help with accessing a function from within the main and within other functions and im not sure how to do it .

whats hard about this....

Code:

---

#include<stdio.h>
void func1(void); /* prototype for function */
void func2(void);

int main()
{
func1(); /* function call */
func2();
return 0;
}

void func1(void) /* function definition */
{
printf("We are in func1 now \n");
}

void func2(void)
{
printf("We are in func2 now \n");
}

---

yes that sounds nice an easy but i need the function to create an index from a specified input of chars and digits. i need to access this function from within another function and then use that index to access a file

simple.....

int GetIndex(char* Key)
{
/* Do stuff with key to get an int index */
return index;
}

then when you call it....

int index;
index=GetIndex("ABC123DEF567");

etc.
