Find the errors from following C function :

    char* f(int i) {
            int i; 
            char buffer[20];
            switch ( i ) {
                    1: strcpy( buffer, "string1");
                    2: strcpy( buffer, "string2");
                    3: strcpy( buffer, "string3");
                    default: 
                    strcpy(buffer, "defaultstring");
            }
            return buffer;
    }

this is c funtion not C++, I think it has to do with type conversion my compiler give warning that declaration of int i shadows a parameter.
