Finding the lowest score

[namcintosh]

First of all, here is my program:

#include <iostream>
#include <conio>
using namespace std;
 
//Function prototype
void getscore(int&, int&, int&, int&, int&);
void findLowest (int, int, int, int, int, int);
int main()
{
        int LO, score1, score2, score3, score4, score5;
 
        getscore (score1, score2, score3, score4, score5);
        findLowest(LO, score1, score2, score3, score4, score5);
 
        getch();
        return 0;
}
 
 
 
void getscore (int &score1, int &score2, int &score3, int &score4, int &score5)
{
        cout << "Enter first score: ";
        cin  >> score1;
        cout << "Enter second score: ";
        cin  >> score2;
        cout << "Enter third score: ";
        cin  >> score3;
        cout << "Enter fourth score: ";
        cin  >> score4;
        cout << "Enter fifth score: ";
        cin  >> score5;
}
 
void findLowest(int LO, int score1, int score2, int score3, int score4, int score5)
{
 
        LO = 1000;
 
        if (score1 < LO)
        {
            LO = score1;
            cout << "The lowest score is" <<LO <<endl;
        }
 
        else if (score2 < LO)
        {
            LO = score2;
            cout << "The lowest score is" <<LO <<endl;
        }
        else if (score3 < LO)
        {
            LO = score3;
            cout << "The lowest score is" <<LO <<endl;
        }
        else if (score4 < LO)
        {
            LO = score4;
            cout << "The lowest score is" <<LO <<endl;
        }
        else if (score5 < LO)
        {
            LO = score5;
            cout << "The lowest score is" <<LO <<endl;
        }
}

Okay, I got one part of the program to work right. The only problem is finding the lowest score.

I declared some if/else if statements and also assigned LO to a large number, such as 1000. Here's my output:

Enter first score: 100
Enter second score: 75
Enter third score: 55
Enter fourth score: 100
Enter fifth score: 85
 The lowest score is100

Do you see what I mean? It declares 100 as the lowest number. Why is it doing that?

[ilikepython]

OK, so how can I get it to return a value

From the function? You add "return s;" at the end of the function.

[Savage]

Yup.

And then when u call the function call it like:

int s;//this is in main

s=findLowest(sc ore1,score2,sco re3,score4,scor e5);

and also:
function must be of :int,float...al l those types except void which can't return anything.

[namcintosh]

Yup.

And then when u call the function call it like:

int s;//this is in main

s=findLowest(sc ore1,score2,sco re3,score4,scor e5);

Okay, thanks!

[Savage]

Okay, thanks!

U are welcome!!

U are welcome!!

Ok, but now I am having problems with the void calcAverage() function. This function should calculate and display the average of the four highest test scores. It should also be called just once by main, and should be passed the five scores.

Now, here s my program so far:

#include <iostream>
#include <conio>
using namespace std;
 
//Function prototype
void getscore(int&, int&, int&, int&, int&);
int findLowest (int, int, int, int, int, int);
void calcAverage (int)
int main()
{
        int average, score1, score2, score3, score4, score5;
 
        getscore (score1, score2, score3, score4, score5);
        calcAverage (average)
        getch();
        return 0;
}
 
 
 
void getscore (int &score1, int &score2, int &score3, int &score4, int &score5)
{
        cout << "Enter first score: ";
        cin  >> score1;
        cout << "Enter second score: ";
        cin  >> score2;
        cout << "Enter third score: ";
        cin  >> score3;
        cout << "Enter fourth score: ";
        cin  >> score4;
        cout << "Enter fifth score: ";
        cin  >> score5;
}
 
void calcAverage (int average)
{
        int average;
}
int findLowest(int small, int score1, int score2, int score3, int score4, int score5)
{
        small =score1;
 
        if(small>score2)
        {
        small=score2;
        }
        if(small>score3)
        {
        small=score3;
        }
        if(small>score4)
        {
        small=score4;
        }
        if(small>score5)
        {
        small=score5;
        }
        return small; 
}

I know how to calculate the average: Average = ((score 1 + score 2 + score 3 + score 4 + score5 -SMALL))/4

I just don't know how to put it in the program

[sicarie]

This function should calculate and display the average of the four highest test scores. It should also be called just once by main, and should be passed the five scores.

void calcAverage (int)
int main()
{
        calcAverage (average)
}
void calcAverage (int average)
{
        int average;
}
 

I know how to calculate the average: Average = ((score 1 + score 2 + score 3 + score 4 + score5 -SMALL))/4

I just don't know how to put it in the program

I snipped the above for brevity. So reading what the function should do, what do you need to pass to it, and where do you put that? Once you have those, they are considered local variables, so your implementation should be ready to work.

(If you're getting stuck on the function declarations/implementations , look at the example of the last one you just made. What did the outline say for what you needed to do to create it, and then how did you create it - where did you put the things it said.) I'm pretty sure you can figure this one out - just look at the one you've already created as an example.

[namcintosh]

Okay, this is what I came up with:

void getscore(int&, int&, int&, int&, int&);
int findLowest (int, int, int, int, int, int);
 void calcAverage (int)
int main()
{
        int average, score1, score2, score3, score4, score5;
 
        getscore (score1, score2, score3, score4, score5);
        calcAverage (average)
        getch();
        return 0;
}
 
 
 
void getscore (int &score1, int &score2, int &score3, int &score4, int &score5)
{
        cout << "Enter first score: ";
        cin  >> score1;
        cout << "Enter second score: ";
        cin  >> score2;
        cout << "Enter third score: ";
        cin  >> score3;
        cout << "Enter fourth score: ";
        cin  >> score4;
        cout << "Enter fifth score: ";
        cin  >> score5;
}
 
void calcAverage (int average)
{
        int average;
        average = ((score1 + score2 + score3 + score4 + score5)-small)/4;
 
        cout << average;
}
int findLowest(int small, int score1, int score2, int score3, int score4, int score5)
{
        small =score1;
 
        if(small>score2)
        {
        small=score2;
        }
        if(small>score3)
        {
        small=score3;
        }
        if(small>score4)
        {
        small=score4;
        }
        if(small>score5)
        {
        small=score5;
        }
        return small; 
}

But now, when I try to run the program, I am getting a declaration syntax error (see bold) Why is it doing that???

[Savage]

[quote=namcintos h]Okay, this is what I came up with:



void calcAverage (int)


It looks like u are missing semicolumn.

Savage

[Ganon11]

It looks like you are missing a semicolon after the declaration.

[Savage]

I can't belive that i writed semicolumn instead of semicolon.LOL
