C++ program jumps for noobie

[bandito9111]

I am a noobie c++ programmer and have a Question on how to
complete this program

I want to be able to input a or v and then be able to jump to the area to input and calculate my result and display
I tried goto(i know dont laugh)
and tried bool but it didnt work

someone help me


#include<iostream>


int main()

{

int area, volume, height, width, length;

std::cout<<"\nDo you wish to calculate Area or volume?(A/V)";

char av;

std::cin>>av;


{ //input and calculate area
std::cout<<"\ninput width:";
std::cin>>width;
std::cout<<"\ninput length:";
std::cin>>length;
area=length*width;
std::cout<<"area is:";
std::cout<<area;
}

{ //input and calculate volume
std::cout<<"\ninput width:";
std::cin>>width;
std::cout<<"\ninput height:";
std::cin>>height;
std::cout<<"\ninput length:";
std::cin>>length;
volume=height*width*length;
std::cout<<"\nvolume is:";
std::cout<<volume;
}
return 0;

}

first use code tags.

as for the problem, just use if statements.

if(av == 'a') {
   //area calculations
} else {
   //volume calculations
}

and for goto, not recommended. it tends to be sloppy code.

Try using IF statements:

if (av == 'a')
{
     // Calculate Area....
}

else if (av == 'v')
{
     // Calculate Volume....
}
