Help on simple arrays

brookeville · #1 09-Nov-2004, 01:45

Hello again, I have encountered another problem, this time, dealing with arrays. I need help in correcting my program that I have posted below to meet the requirements of the assignment.

"Write a program that lets the user enter 10 values into an array. The program should then display all values as in the example format shown below:"

You have entered:

3

4

8

3

5

9

0

45

4

3

Here is my program so far:

CPP / C++ / C Code:

#include <iostream>
#include <cctype>
#include <iomanip>

using namespace std;

#define MAX 11  //Define MAX

int main()
{

float numbers[MAX];
int count = 0;
int loop = 0;

cout << "Enter ten numbers, separated by commas:" << endl;


for(loop=1; loop < MAX; loop++)//for loop
{
	cin >> numbers[loop];
}

	cout << numbers[loop];
	cout << "You have entered:" << numbers << endl << endl;
    
	return 0;
}

I want to modify it to 1) allow the user to enter 10 numbers, separated by commas (which I haven't learned how to do), and 2) output all the numbers as in the example format above. Any help you can offer will be truly appreciated. Thanks again!

Put the output in another for loop. That's about all you need.

Walt, how about this? I fixed a few errors but still would like to know how to input numbers separated by commas, like 1,2,3,4,5,6,7,8,9,0, etc... in my array.

CPP / C++ / C Code:

#include <iostream>
#include <cctype>
#include <iomanip>

using namespace std;

#define MAX 11  //Define MAX

int main()
{

float numbers[MAX];
int count = 0;
int loop = 0;

cout << "Enter ten numbers: " << endl;


for(loop=1; loop < MAX; loop++)//for loop
{
	cin >> numbers[loop];
}

cout << "\n\nYou have entered:\n\n";

for (loop=1; loop < MAX; loop++)
	{
		cout << numbers[loop] << endl << endl;
	}

return 0;	
}

Also, my teacher suggested that I try another program for fun. It was one right from the book that deals with arrays. It asks "Write a program that lets the user enter 10 values into an array. The program should then display those values in ascending order." I'll post it when I (hopefully) get it done!

Doing this will require

the horrendous scanf()
higher level function that I don't like using (strtok())
parsing the input line yourself

I'd recommend for now not worrying about it. You'll get into that kind of stuff soon enough.

I see... Well, as long as my program meets the requirements of the assignment, it should be perfectly fine. I'll take your advice and wait until I learn about it, before attempting it. Thanks again, Walt!
