Answer 1

Ok fine Let me Explain the code first to you i.e what exactly happens when you execute the program.

Intially main() (main method) is called i.e where the execution of the program begins. Provide the inputs for a,b,c and the function result(a,b,c,trianglearea,triangleperimeter) is called . now the pointer moves to the result() function .The result() function should pass the values such as trianglearea,triangleperimeter to the main() function so the return type of the function should not be void instead it should be int or double (if you want an integer value return type should be int similarly double).

return the values of trrianglearea,triangleperimeter by making it as a single value (i.e making pair)

make_pair(trianglearea,triangleperimeter) . make_pair is the function present in utility.h header file

Now the funtion result() returns a value to the main method now the main method should hold the values since the scope the variables are different i.e trianglearea,triangleperimeter has local scope

now there are stored in variables as x,y temporarly.

tie(x,y)=result(a,b,c,&trianglearea,&triangleperimeter) // tie is method used to unpack the varibales and it is present in tuple.h

the output statement should be as

cout<<"Areaof triangle"<<x<<"perimeter"<<y<<endl;
