I am wanting to add more math functions to this prog.

As I said I'm a noobie(learning c++ 6 mo's )

I am starting to learn pointers / arrays and need help.

any way to simplify and make program flow better

Thanks

Code:#include<iostream> int main() { int area, volume, height, width, length, sphere, circ, vols, pi, done, y, n ; bool finished = true; // ADDED THIS: will hold true if finished else it will hold false char temp = '\0'; // Used for user input, set to empty. pi = 3.14159265; //make pi=to value do //start do loop { std::cout<<"\nDo you wish to calculate Area or Volume or vol of Sphere?(A/V/S)"; char avs; //int chars a v and s std::cin>>avs; //input one of the three if (avs == 'a') //if input=this do the below then goto the end { //input and calculate area std::cout<<"\ninput width in inches:"; std::cin>>width; std::cout<<"\ninput length in inches:"; std::cin>>length; area=length*width; //formula for context std::cout<<"\narea is:"; std::cout<<area; std::cout<<" Square Inches\n"; } else if (avs == 'v') //if input=this do the below then goto the end { //input and calculate volume std::cout<<"\ninput width in inches:"; std::cin>>width; std::cout<<"\ninput height in inches:"; std::cin>>height; std::cout<<"\ninput length in inches:"; std::cin>>length; volume=height*width*length; //formula for context std::cout<<"\nvolume is:"; std::cout<<volume; std::cout<< " Cubic Inches\n"; } else if (avs == 's') //if input=this do the below then goto the end { //input and calculate circumfrence std::cout<<"\n input diameter/2 or radius"; std::cin>>sphere; vols = 4*pi*(sphere*sphere); //formula for context circ = (2*sphere)*pi; //formula for context std::cout<<"\narea is:"; std::cout<<vols; std::cout<< "Cubic inches"; std::cout<<"\nby the way the circumfrence is"; std::cout<<circ; std::cout<< " Inches\n"; } // Does the user wish to continue or quit? std::cout<<"\nDo you want to quit? (Y)es or (N)o?"; std::cin >> temp; if(temp == 'n' || temp == 'N') done = false; else if(temp == 'y' || temp == 'Y') done = true; else { std::cout << "Invalid Input..."; return 0; } } while(!done) ; return 0; //end of volarea2,1.cpp }
