a prob?

Code:

---

#include<iostream>
#include<conio.h>
using std::cout;
using std::cin;
using std::endl;
// function prototype
double small(double,double); 

int main()
{
    // declare varibales
    double num1,num2; 
    // read values
    cout<< "Enter two double values:\t";   
    cin>> num1 >> num2;
    // display result
    cout<< small(num1,num2);

getch();
}
// define small()
double small(double value1,double value2)
{ 
    // declare alias
    double minValue;
    // check smallest value
    double minValue=value1;
    if(value2<minValue)
    minValue=value2;
    return minValue;
}

It gives me parse errors before functions prototype.

The same code when tries with an integer value gives correct output. What is wrong in this code?

You have a redefinition of minValue in your small function and your main doesn't return a value.

didn't get that/

Code:

---

#include<iostream>
#include<conio.h>
using std::cout;
using std::cin;
using std::endl;
// function prototype
double small(double,double); 

int main()
{
    // declare varibales
    double num1,num2; 
    // read values
    cout<< "Enter two double values:\t";   
    cin>> num1 >> num2;
    // display result
    cout<< small(num1,num2);

getch();
    return 0; // I think recent standards say this is implicit, but why leave it to chance?
}
// define small()
double small(double value1,double value2)
{ 
    // declare alias
    double minValue;
    // check smallest value
    /*double*/ minValue=value1; // You can only define a variable once
    if(value2<minValue)
    minValue=value2;
    return minValue;
}

got it now thanku/
