Okay, i have written a code to figure out the area of all different shapes but i can't get it past hte pasrt where the client chooses what they want to find the area of.
this is my code:

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

int getChoice();
int circle();
int rectangle();
int trapazoid();
int triangle();
int parallelogram();

int main()
{

    int choice;
    do{
        choice = getChoice();
        if ( choice == 1 ) circle();
        else if ( choice == 2 ) rectangle();
        if ( choice > 6 || choice < 1 )
        cout << "\nPlease enter a valid number.\n"<<endl;
        else if ( choice == 3 ) trapazoid(); 
        if ( choice == 4 ) triangle();
        else if (choice == 5) parallelogram();
      } while ( choice != 6);  
}

int getChoice()
{

    int x;
    cout << "                ||~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~||" << endl;
    cout << "                ||      Area Of 2-D Shapes        ||" << endl;
    cout << "                ||---------------------------------------------||" << endl;
    cout << "                || Press 1 to find the area of a circle        ||" << endl;
    cout << "                || Press 2 to find the area of a rectangle     ||" << endl;
    cout << "                || Press 3 to find the area of a trapazoid     ||" << endl;
    cout << "                || Press 4 to find the area of a triangle      ||" << endl;
    cout << "                || Press 5 to find the area of a parallelogram ||" << endl;
    cout << "                || Press 6 to quit                             ||" << endl;
    cout << "                ||                                             ||" << endl;
    cout << "                ||~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~||\n" << endl;
    cout << "\nPlease enter number for your choice: ";
    cin >> x;
}

int circle()

{

	double answer1;
	double r;
	cout << "\nEnter Radious of the circle = ";
    cin >> r;
    answer1 = 3.14159*r*r;
    cout << "\nArea = " <<answer1;

}

int rectangle()

{

	double answer2;
	double w;
	double h;
	cout << "\nEnter the width of the rectangle = ";
    cin >> w;
    cout << "\nEnter the height of the rectangle = ";
    cin >> h;
    answer2 = w*h;
    cout << "\nArea = " << answer2;

}

int trapazoid()

{
    
    double answer3;
    double h;
    double b1;
    double b2;
    cout << "\nEnter the hight of the trapezoid: ";
    cin >> h;
    cout << "\nEnter the bottom base of the Trapezoid: ";
    cin >> b1;
    cout << "\nEnter the top base of the Trapezoid: ";
    cin >> b2;
    answer3 = 0.5 * h * (b1 + b2);
    cout << "\nArea = " << answer3;
 
}
     
int triangle()

{
    
    double answer4;
    double h;
    double b;
    cout << "\nEnter the base of the triangle: ";
    cin >> b;
    cout << "\nEnter the height of the triangle: ";
    cin >> h;
    answer4 = 0.5 * b * h;
    cout << "\nArea = " << answer4;
    
}

int parallelogram()

{
    
    double answer5;
	double b;
	double h;
	cout << "\nEnter the base of the Parallelogram = ";
    cin >> b;
    cout << "\nEnter the height of the Parallelogram = ";
    cin >> h;
    answer5 = b*h;
    cout << "\nArea = " << answer5;
    
}

Your getChoice( ) function gets user input, but does not pass it back to main( ).

cout << "\nPlease enter number for your choice: ";
    cin >> x;
    return x;    //add this so the choice gets sent back to main( )
}
