please help, i'm really stuck

I know this is a mess... I got parts of it to work (the square part) but when I add in triangle...I get lots of errors

Code:

---

#include <iostream>
#include <string>
#include <cstdlib>

using namespace std;

void instructions();        //Instructions to the user.
void calculations();        //Calculates the area of a triangle or square.

int main ()
{
// Instructions for the user.
        instructions();

// Calculates the area.
        calculations();

return 0;
}
// Instructions.
        void instructions()
{       
        cout << "This program calculates the area of "
                << "either a square or a triangle.  You will" << endl;
        cout << "first be asked to enter a letter "
                << "(s for square, or t for triangle) to identify" << endl;
        cout << "which kind of figure you want the area computed for.  "
                << "Be sure to type a " << endl;
        cout << "lower-case letter, and not a capital letter.  "
                << "Then you will be asked for " << endl;
        cout << "dimensions of the figure.  Always hit the <Enter> "
                << "key after typing whatever " << endl;
        cout << "has been asked for." << endl << endl;

}  // End instructions.




        // Calculations.
        void calculations()
       
{
        int squ1, tri1;
        char let1;
        float areas; 
        float areat;

cout << "Type the letter s to compute the area of a square, "
                << "or type t for a triangle: ";
        cin >> let1;

        if (let1=='s'){
                cout << "Enter the length of a side for the square: ";
                cin >> squ1;
                if (squ1 > 0)
                {//Calculates the area of a square
                areas = (squ1 * squ1);
                cout << "The area of a square with a side of " << squ1
                        << " is " << areas << endl;}
                        else (squ1 <= 0)
                        {cout << "It is impossible to have a square with a side
                                  << "whose length is " << squ1 << endl;}

        else
                if (let1=='t'){
                cout << "Enter the length of the base for the triangle: ";
                cin >> tri1;

                //Calculates the area of a triangle
                areat = (.5 * tri1 * tri1);
                cout << "The area of a triangle with a base of " << tri1
                        << " and a height of " << tri1 << " is " << areat << endl;
                }
                else {
                        cout << "This program can only recognize the "
                                << "lower-case letters s and t.  Sorry." << endl;

Some pieces of advice:
1. Indent your code properly!
2. Stop placing your brackets like that, choose a style ans stick to it, don't use several different ones at the same time.
3. Skip some lines to make your code clearer.
4. Align your statements to a certain column.
5. Put spaces between an operator and its operands.

So, here the code, a if was missing after an else and before the conditionnal statement. And, you forgot to place a closing bracket somewhere. (but, well, if you didn't use such a messy style...)

[edit]My indentation is bad because the original code used tabs instead of spaces.

Thanks!! Actually I did get it cleaned up and it works now. I just need some help adjusting the spaces. It comes out with spaces between each line, but I need to have the code display without spaces. (I hope that made sense)

I didn't get it... about your space thing, are you talking about the screen display, the forum code display or your code itself?

I don't know the right terminology, but here's how it displays when the program is executed:

******************************************

Type the letter s to compute the area of a square, or type t for a triangle: s

Enter the length of a side for the square: 3
The area of a square with a side of 3 is 9

Type the letter s to compute the area of a square, or type t for a triangle: t

Enter the length of the base for the triangle: 4

Enter the height of the triangle: 6


The area of a triangle with a base of 4 and a height of 6 is 12

Type the letter s to compute the area of a square, or type t for a triangle:

******************************
I'd like to keep the spaces only between each new "Type the letter s to compute...." and delete the ones in between so it looks like

space
Enter the length of the base:
Enter the height:
The area of a triangle is:
space

Well, I think you're able to do it by yourself, really and without much efforts, so I'll let you do it; just remove the endl where you do'nt wnat a space.
