void Strfun(char *ptr)

Here,

void is the returns type of the function i.e. it will return nothing.
Strfun is the name of the function.
char *ptr is the character pointer that will store the base address of the character array (string) which is going to be passed through main() function.

Function Calling

Strfun(buff);

Here,

buff is the character array (string).
