Problems with a program that does two functions

[AZRebelCowgirl73]

can anyone help me I cant get this program to run, it errors during bugging! I thought I was pretty close to having it, but I can't get it! thanks!


//C++ Project 3:
//For your Project 3 Write a program that has two separate functions.
//One function will determine and return the smallest of three numbers
//and the other function will determine and return the average of three
//numbers. Both functions should return a value. This should be submitted
//in your Assignments folder. Please submit your work as a .cpp file
//attachment so that it does not lose the spacing/indentations. Your file
//should be named lastname1.cpp. For example, my program would be Jackson1.cpp.

#include <iostream>
using namespace std;
int main()
{
int num1, num2, num3, average;
cout << "Enter any three integers: ";
cin >> num1;
cin >> num2;
cin >> num3;
cout << "The three integers you entered are " << num1 << " , " << num2 << " and " << num3 << endl;
average = (num1 + num2 + num3)/3;
cout << "The average of the three integers" << endl;
cout << "you have entered is." << average << endl;
return 0;
}

{
int num1, num2, num3, min;
cout << "Please enter any three integer: ";
cin >> num1;
cin >> num2;
cin >> num3;
cout << "The three integers you entered are " << num1 << " , " << num2 << " and " << num3 << endl;
cout << "The number with the smallest value is ";
if (num1 < num2)
min = num1;
else
min = num2;
if (num3 < min)
min = num3;
cout << min << "." << endl;
int i;
cin >> i;
return 0;
}

Do you mean it gives an error during compilation? Which I would expect it to do.

You have not defined 2 functions, you have defined 1 function, main, but then you have tried to define a second function but not declared it you have only given a function body.

 
#include <iostream>   
using namespace std;   
 
int main()  
{ 
    <snipped>
}
 
/* you need to declare the function here something like */
 
int MyFunction()
{ 
    <snipped>
}

Thanks for the help, I had int main in the first time, but i guess because they both had the same name it was not compiling. I deleted it and forgot to change it! LOL It compiles now and again Thanks! However now I cant get both parts to run? Am I doing something wrong? The first part which averages the integers runs, but then the second part which should tell you which number is the smallest does not show up? Any Ideas? Thanks!!!!

I think you have mis-interpreted your question (but i also think it is badly worded so may be you should check with your lecturer).

I think that the structure this program requires is

/* Include relevent headers */
 
 
/* Predeclare functions in use */
static int Average(int,int,int);
static int Smallest(int,int,int);
 
 
int main()
{
    int x, y, z;
    int average;
    int smallest;
 
    /* Code to get 3 integers x, y and z */
 
    /* Call functions to get statistics */
    average = Average(x, y, z);
    smallest = Smallest(x, y, z);
 
    /* Output data x, y, z, average and smallest */
}
 
static int Average(int x, int y, int z)
{
    /* code to calculate average of 3 integers x, y and z */
 
   return <result>;
}
 
int Smallest(int x, int y, int z)
{
    /* code to calculate smallest of 3 integers x, y and z */
 
   return <result>;
}
 

i.e. 1 main function geting the data and outputing the results calling 2 functions that each calculate 1 statistic and return it.

Note this is only the structure however since you already have all the functional code required I figure you can probably manage to get it working from here.
