Function overloading has a return type...

Ex:
#include<iostream>
using namespace std;
//Function 1:

int max(int a, int b)
{
return (a>b)? a:b;
}

//Function 2:

float max(float a, float b)
{
return(a>b)? a:b;
}

int main()
{
int c;
float d;
c=max(5,4); //will display 5
cout<<c<<endl;
d=max(3.14,6.15); //will display 6.15
cout<<d<<endl;
return 0;
}

Important Concepts in Fn. Overloading:
a) Fun Overloading depends upon the type/number/order in
which the arguments are passed...
b) Fun Overloading can take place for a function which is
within the same scope... (i.e.) both function 1:, and
Function 2: should be in the same { ...} (both the
functions are within main() (i.e. same scope)...

write a code for this. serial_number contained in the header of the file will be read , if this serial number is less than a previous serial number within a successfully processed file, or is the same as another serial number within a successfully processed file, or if the field contains anything other than 7 digits, then the file must error with the reason ‘Invalid SERIAL_NUMBER’.
