    Newbie having problems with errors

    I am in a Programming design class, not even C++, and am basically trying to make a program from a design I did. I have very limited experience with C++ and feel through reading online that I get the gist of this, I am just having a few errors I can't figure out.


    Here is the code
    Code:
    // Basic C++ info
    
    #include <iostream>
    #include <string>
    
    using namespace std;
    
    // Declare Global Variables
    float fltIncome, fltTaxowed
    
    // Modules
    void TaxTable();
    void LowBracket();
    void MiddleBracket();
    void HighBracket();
    
    // Made the Modules seperate so that if the tax rate changes, you just have to change the module and not entire program
    
    int Main()
    {
    	cout << "Welcome to the WilliamK99 Tax Calculator" << endl;
    	cout << "Please enter your yearly annual taxable income" << endl;
    	cin >> fltIncome;
    	TaxTable();
    
    	return 0;
    }
    
    
    void TaxTable()
    {
    	if ((fltIncome > 0) && (fltIncome <= 50000)){
    	LowBracket ();}
    	else{
    		if ((fltIncome > 50000) && (fltIncome <= 100000)){
    		MiddleBracket();}
    		else{
    			if (fltIncome > 100000) {
    			HighBracket();}
    			else{
    				{cout >> "You have entered an invalid number";
    				}
    			    }
    		     }
    	   }
    	
    return;
    }
    void LowBracket()
    {
    	fltTaxowed = fltIncome * .05;
    	cout << "You owe " << fltTaxowed << " dollars!";
    	return;
    }
    
    void MiddleBracket()
    {
    	fltTaxowed = ((fltIncome - 50000) * .07) + 2500;
    	cout << "You owe " << fltTaxowed << " dollars!";
    	return;
    }
    
    void HighBracket()
    {
    	fltTaxowed = ((fltIncome - 100000) * .09) + 6000;
    	cout << "You owe " << fltTaxowed << " dollars!";
    	return;
    }
    The errors are attached. Thanks for any guidance you can give me. Again I am not looking for the answers, I am looking for a gentle nudge into the right direction.

    1. You are missing a semicolon here:
    Code:
    float fltIncome, fltTaxowed
    2. Your >> should be << (you want to send the info to cout, not get something FROM cout):
    Code:
    cout >> "You have entered an invalid number";

    Compilers can produce warnings - make the compiler programmers happy: Use them!
    Please don't PM me for help - and no, I don't do help over instant messengers.

    Try using an updated compiler instead, such as Visual Studio. Borland is old, outdated.
    And I mentioned to someone else,

    Code:
    	if ((fltIncome > 0) && (fltIncome <= 50000)){
    	LowBracket ();}
    	else{
    		if ((fltIncome > 50000) && (fltIncome <= 100000)){
    		MiddleBracket();}
    		else{
    			if (fltIncome > 100000) {
    			HighBracket();}
    This will only serve to confuse.

    Code:
    	if ((fltIncome > 0) && (fltIncome <= 50000)){
    		LowBracket ();
    	}
    	else{
    		if ((fltIncome > 50000) && (fltIncome <= 100000)){
    			MiddleBracket();
    		}
    		else{
    			if (fltIncome > 100000) {
    				HighBracket();
    			}
    This is far better. Wouldn't you agree? Much easier to read and see the ending bracket.

    Thanks so much, I feel so lame right now, I read and re-read my code and overlooked both minor errors.

    I appreciate the help.
