Question

Would someone check this? This part of my code does not produce its desired purpose.

[code]
int a=0,b=0;
cout<<"Please choose the root domain: "<>h; if (h==1) a=1;b=2; if (h==2) a=-2;b=-1; if (h!=1 && h!=2) cout<<"Error!"< 14 years ago

Answer 1

Enclose your if statement code blocks with curly braces (except for the last one since you only have one line of code in it)

Otherwise, 'b = 2' and 'b = -1' will be executed even if h is not 1 or 2.

Answer 2

so your code can look like this:

int a = 0, b = 0, h;

cout << "Please choose the root domain: " << endl;
cout << "1. [1,2] 2.[-2, -1] " << endl;
cin >> h;

if (h == 1) {
a = 1;
b = 2;
}
if (h == 2) {
a = -2;
b = -1;
}
if (h != 1 && h != 2)
cout << "Error!" << endl;

Answer 3

int a=0, b=0,h;

cout<<"\nplease the root domain :"<<endl;
cout<<"\n1 . [1,2] 2.[-2,-1]"<<endl;
if (h==1)
{
cout<<"\n\na=1";
<<"\n\nb=2";
}
if(h==2)
{
cout<<"\n\na=-2";
<<"\n\n b=-1";
}
if(h!=1 && h!=2)
{
cout<<"Error"<<endl;
}

Answer 4

if you want the message to be prompet rapidly u can use sentinel control statement(while loop)
