Thread: need help with code

easier to read...

Code:

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

using namespace std;


int main()
{

char letter; // users menu choice
int num; // the number of numbers that the user wants to enter
int num1; // user inputed variables
int ans; // largest variable
int answ; // smallest variable

cout << " Please type in your choice by entering a b or c " << endl;
cout << " a= Find the largest number with a known quantity of whole two digit numbers " << endl;
cout << " b= Find the smallest number with an unknown quantity of numbers " << endl;
cout << " c= Quit " << endl;

cin >> letter;

if (letter == 'a')
{
	cout << "How many numbers would you like to enter? " << endl;
	cin >> num;

	cout << "Please enter a number and press enter. " << endl;
	cout << endl;

	ans = 0;

	int count; // declaring loop control variable

	for (count = 0; count < num; count = count++)
	{
		cin >> num1;
		ans = num1;
		cin >> num1;
		if (num1 > ans)
		{
			ans = num1;
			cin >> num1;
		}

		else if (ans > num1)
		{
			ans = ans;
			cin >> num1;
		}
	}

cout << "The Largest number you entered was " << ans << endl;
cout << endl;
return main();
}

else if (letter == 'b')
{
	cout << " Enter as many numbers as you like, when you are finished enter '99' " << endl;
	cout << endl;

	answ = 0;

	while (answ != 99)
	{
		cin >> num1;
		answ = num1;
		cin >> num1;


		if (num1 < answ)
		{
			answ = num1;
			cin >> num1;
		}
 
		else if (answ < num1)
		{
			answ = ans;
			cin >> num1;
		}
	}

	cout << "The smallest number you entered was " << answ << endl;
cout << endl;
}


system("pause");

return 0;

}

Properly indented:

Code:

#include <string>

	cout << " b= Find the smallest number with an unknown quantity of numbers " << endl;
	cout << " c= Quit " << endl;

	cin >> letter;

	if (letter == 'a')
	{
		cout << "How many numbers would you like to enter? " << endl;

		cout << endl;

		ans = 0;

		int count; // declaring loop control variable

		for (count = 0; count < num; count = count++)
		{
			cin >> num1;
			ans = num1;
			cin >> num1;
			if (num1 > ans)
			{
				ans = num1;

			}
		}

		cout << "The Largest number you entered was " << ans << endl;

	}

	}


	system("pause");

	return 0;

Take a look at the red line. It assigns ans to answ. Where do you initialize ans? Where do you store data in it?
Also, you shouldn't recursively call main. Instead, implement this logic using loops. It shouldn't be difficult so long as you write down the logic on paper.
