Consider the following code fragment:
int main(void) {
int m = 4;
mystery ( m );
mystery ( m );
printf("%d", m);
return 0;
}
What is the output on the monitor if mystery is defined as
follows ?
void mystery (int m) {
m = m+3;
}

Answer / c++ coder
Output will be 4 only.
since the argument is not passed by reference so a local
copy of m is used in the function call which is local to
mystery() it will not have any impact on the variable m
which is used in main() function.

but in this program fun mystery() in not defined and still
it is called so it will give error.
