Find Lowest and Highest of Array

[3voN6Up4]

Hey guys, I am having trouble with finding the lowest and the highest of an array. Basically, there's a string array shown below and an int array. I want to find the highest and the lowest of the set but I want it to say "String has the highest" or "String has the lowest". I need help on the int HIGHEST_LOWEST() function.

  #include <iostream>
#include <string>
using namespace std;
string SALSA_TYPES[5] = {"Mild", "Medium", "Sweet", "Hot", "Zesty"};
int JARS_SOLD[5];
const int count = 5;
int SALSA_TYPE_SALES() //function to find sales for each salsa type.
{
    cout << "\n\n\n\n\n\n\n\n\n\n\n\n\n\n" << endl;
    cout << "========================================================" << endl;
    cout << "Salsa Type: ";
    for (int i = 0; i < count; i++)
    {
        cout << SALSA_TYPES[i] << ", ";
    }
    cout << endl;
    cout << "Jars Sold: ";
    for (int i = 0; i < count; i++)
    {
        cout << JARS_SOLD[i] << ", ";
    }
    cout << endl;
    cout << "========================================================" << endl;
    cout << "\n~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~\n" << endl;
}
int SALSA_TOTAL() //function to find total sales (add all jars together).
{
    cout << "========================================================" << endl;
    int total = 0;
    for (int i = 0; i < count; i++)
    {
        total = total + JARS_SOLD[i];
    }
cout << "Total jars sold: " << total << endl;
    cout << "========================================================" << endl;
}
int HIGHEST_LOWEST() //function to get the names of the highest selling and lowest selling types.
{
    
}
int main()
{
    for (int i = 0; i < count; i++)
    {
        cout << "How many jars of the " << SALSA_TYPES[i] << " salsa were sold?" << endl;
        cin >> JARS_SOLD[i];
        cout << "You've entered " << JARS_SOLD[i] << endl;
    }
    if (JARS_SOLD[count] < 0)
    {
        cout << "Please reenter a POSTIVE integer number: " << endl;
        cin >> JARS_SOLD[count];
    }
SALSA_TYPE_SALES();
SALSA_TOTAL();

}

This is what I have. I've determined the minimum and the maximum easily enough, but I can't figure out how to say "Zesty had the lowest amount of jars sold" I need to have the max/min equal whatever value in the string array.

#include <iostream>
#include <string>
using namespace std;
string SALSA_TYPES[5] = {"Mild", "Medium", "Sweet", "Hot", "Zesty"};
int JARS_SOLD[5];
const int count = 5;
int SALSA_TYPE_SALES() //function to find sales for each salsa type.
{
    cout << "\n\n\n\n\n\n\n\n\n\n\n\n\n\n" << endl;
    cout << "========================================================" << endl;
    cout << "Salsa Type: ";
    for (int i = 0; i < count; i++)
    {
        cout << SALSA_TYPES[i] << ", ";
    }
    cout << endl;
    cout << "Jars Sold: ";
    for (int i = 0; i < count; i++)
    {
        cout << JARS_SOLD[i] << ", ";
    }
}
int SALSA_TOTAL() //function to find total sales (add all jars together).
{
    cout << "\n========================================================" << endl;
    int total = 0;
    for (int i = 0; i < count; i++)
    {
        total = total + JARS_SOLD[i];
    }
cout << "Total jars sold: " << total << endl;
    cout << "========================================================" << endl;
}
int HIGHEST_LOWEST()
{
    int minimum = JARS_SOLD[0];
    int maximum = JARS_SOLD[0];
    cout << "The minimum is: ";
    for (int i = 0; i < count; i++)
    {
        if (minimum > JARS_SOLD[i])
        {
            minimum = JARS_SOLD[i];
        }
    }
    cout << minimum << endl;
    cout << "The maximum is: ";
    for (int i = 0; i < count; i++)
    {
        if (maximum < JARS_SOLD[i])
        {
            maximum = JARS_SOLD[i];
        }
    }
    cout << maximum << endl;
cout << "========================================================" << endl;
}
int main()
{
    for (int i = 0; i < count; i++)
    {
        cout << "How many jars of the " << SALSA_TYPES[i] << " salsa were sold?" << endl;
        cin >> JARS_SOLD[i];
        cout << "You've entered " << JARS_SOLD[i] << endl;
    }
    if (JARS_SOLD[count] < 0)
    {
        cout << "Please reenter a POSTIVE integer number: " << endl;
        cin >> JARS_SOLD[count];
    }
SALSA_TYPE_SALES();
SALSA_TOTAL();
HIGHEST_LOWEST();
}

That snippet made me poop myself.. could I have an explanation please? Sorry

[JLBorges]

Do you understand this version?

#include <iostream>
#include <string>

const int N = 5 ;
const std::string salsa_type[N] = { "Mild", "Medium", "Sweet", "Hot", "Zesty" };
int jars_sold[N] = { 12, 7, 14, 23, 35 } ;

// return position of the largest value in the array 'jars_sold'
int pos_max_value()
{
    int pos_maxv = 0 ;

    for( int i = 1 ; i < N ; ++i )
        if( jars_sold[i] > jars_sold[pos_maxv] ) pos_maxv = i ;

    return pos_maxv ;
}

int main()
{
    const int pos = pos_max_value() ;
    std::cout << salsa_type[pos] << " has the largest amount of jars sold (" << jars_sold[pos] << ")\n" ;
}

I understand it, but could you walk me through what you did? Maybe add to my code? It's just the new variable names and I don't know what it is. You just kinda gave me the code without explaining what it does to me. (I'm a noob)

[3voN6Up4]

I just don't get how you make it say which of the string values had the largest amount of jars sold. The conversion from an integer to the string.

What were you doing here? i is an int, isn't it?

int main()
{
    for (int i = 0; i < count; i++)
    {
        // i : int (position in the arrays)
        // SALSA_TYPES[i] : string (salsa type)
        // JARS_SOLD[i] : int (number of jars sold)

        cout << "How many jars of the " << SALSA_TYPES[i] << " salsa were sold?" << endl;
        cin >> JARS_SOLD[i];
        cout << "You've entered " << JARS_SOLD[i] << endl;
    }
    // ...
}

i is indeed an int. You still aren't explaining to me what you are doing.

[JLBorges]

What does this print out? Why?

#include <iostream>
#include <string>

const int N = 5 ;
const std::string salsa_type[N] = { "Mild", "Medium", "Sweet", "Hot", "Zesty" };
int jars_sold[N] = { 12, 7, 14, 23, 35 } ;

int main()
{
    const int pos_max_v = 4 ; // pos_max_value()
    std::cout << salsa_type[pos_max_v] << " has the largest amount of jars sold (" << jars_sold[pos_max_v] << ")\n" ;
}
