need hlp with C++ code

[qwertyasdfgh]

Please tell me why do i get this error saying "error C2181: illegal else without matching if". The last else statement doesn't work. There is a red line under the else. Can some plz tell me the solution. I hv been trying since hours. Please do not worry about variables.

#include <iostream>
#include <iomanip>
using namespace std;

int main()
{
	int a = 10;
	double b;
	int c;

	cout << "Enter" << endl;
	cin >> c;
	{
		if (c >= 1 && c < 20)
			b = c * 0.10 + a;
		else if (c >= 20 && c <= 39)
			b = c * 0.08 + a;
		else if (c >= 40 && c <= 59)
			b = c * 0.06 + a;
		else if (c >= 60)
			b = c * 0.04 + a;
		cout << "It is" << b << endl;
	}	
	    else 
		cout << "It is not." << endl;
	

		cin.get();
		cin.ignore();
		return 0;
}

	    else 
    {
        cout << "It is not." << endl;
        cin.get();
        cin.ignore();
        return 0;
        }
	cout << "It is" << b << endl;

		cin.get();
		cin.ignore();
		return 0;
}

There is probably a better solution but this should work too.

because use used {} to contain your if elses, it read as a block. now you have entered the else right after line 23, now according to the compiler you put an "else" with out an "if". what you should do is remove the {}.

anyone else..??

that doesn't solve my problem..anyone else no one can answer y is it so hard for ppl im just a beginner and i know ppl r experts here..still

I'm not exactly sure what the purpose of your program is, but I do know two things.
1. You have worthless brackets on lines 13 and 23.
2. Indivilual comparisons need to be enclosed in parenthesis like this if ((c >= 1) && (c < 20))

2. Indivilual comparisons need to be enclosed in parenthesis

Not really, but it does improve readability.

I might be getting this rule mixed up with Visual Basic. I'm pretty sure it's required there. Thanks for the clarification though.
