Thread: String + Array = Confused student

Ok so basically I'm working with parallel arrays. One stores the name of an Employee and the other the rate of their pay. Eventually I am allowing the user to input the data....then outputting the highest and lowerst paid employee. However I am having a problem inserting the name into the array. I am completely confused as to what I'm doing wrong. Couldn't find any info on it. Any help would be much appreciated my final is tomorrow.

Code:

#include <iostream>
#include<iomanip>
#include<string>


using namespace std;

const int elements	= 15;
void insertInfo(char name[], double rate[], int elements);
void sort(char name[], double rate[]);
void printExtremes(char name[], double rate[], int elements);

int main()
{
	
	char name[elements];
	double rate[elements];

	insertInfo(name, rate, elements);
	printExtremes(name, rate, elements);

	return 0;

}

void insertInfo(char name[], double rate[], int elements)  // Having trouble with this function
{
	int index = 0;
	cout << "Enter last name and rate of pay: ";

		for (index = 0; index < elements; index++)
		{
			cin.get(name,29,'\n');
			cin >> rate[index];
		
		
		}
}
void printExtremes( char name[], double rate[], int elements)
{
	double largestRate;
	double smallestRate;
	char largestName;
	char smallestName;
	int index;
	int maxIndex = 0;
	for (index = 1; index < elements; index++)
		if (rate[maxIndex] < rate[index])
			maxIndex = index;
	largestRate = rate[maxIndex];
	largestName = name[maxIndex];

		for (index = 1; index < elements; index++)
		if (rate[maxIndex] > rate[index])
			maxIndex = index;
	smallestRate = rate[maxIndex];
	smallestName = name[maxIndex];
	cout << "The highest paid employee is " << largestName << setfill ('-') << setw(20) << "$" << largestRate << endl;

	cout << "The lowest paid employee is " << smallestName << setfill ('-') << setw(20) << "$" << smallestRate << endl;
}

PROBLEM #1
Acme Publishing needs a C++ Program. They have 15 employees. Write a
program for Acme that will allow them to enter 15 last names and 15 pay rates
into parallel arrays. The program should then display the highest and the lowest
pay rate stored in the array with the last name of the corresponding employee.

There's a copy of the problem. Pretty much all the information I found said to use a class or structure.

Awesome thank you very much. Definitely worked but do you know why exactly the original way I coded it wasn't working?

Basically if you typed the name "LARRY" at the prompt,
you had an array that looked like [L][A][R][R][Y]

where you thought you had an array of names like
[LARRY][CURLY][MOE][etc.]

You could've done some char pointer stuff, but that's generally frowned upon in C++, so better off using std::string. (Less headache & confusion)

Ok thanks. I thought the cin.get would have corrected that but obviously not. Thanks a lot for the help.
