how do I add this together?

[takumi05]

I have a loop which outputs the ASCII values but how do I write another loop which adds those values together?


string name;
int a;
cout<<"Enter string : ";
cin>>name;

for(a = 0; a!=name.length(); ++a)
cout<<int(name[a])<<", ";


If I input cat it shows the values 99, 97 116
I want to have the sum of these outputted out instead of those individual values

Thanks

string name; 
int a;
int sum = 0; 
cout<<"Enter string : "; 
cin>>name;

for(a = 0; a!=name.length(); ++a)
{ 
    sum += int(name[a]);
}

cout << sum;

thanks!
I just realised this only works for one word.
how would I make so it would show the value of two words

eg happy dog

thanks

instead of cin>>name use getline(cin,name) so you can get an entire line or get two strings and sum them together

[takumi05]

string name; 
int a;
int sum = 0; 
cout<<"Enter string : "; 
getline(cin,name);

for(a = 0; a!=name.length(); ++a)
{ 
    sum += int(name[a]);
}

cout << sum;

so like that?

[Bazzy]

yes

[takumi05]

i get 0 for the ASCII value output

[Bazzy]

What input did you give? If you hit enter before entering anything, you'll get an empty string

[takumi05]

I put this in so I could put in an input

    getline(cin,name);
    cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');

You don't need to use ignore() when using std::getline().

[takumi05]

I need to for some reason...

that loop there is like just one part. I got other parts to the program.

[takumi05]

   char gender;
   string name;
   
    cout<<"Please enter gender (m/f): ";       //gender selection done as a simple if else statement.
    cin>> gender;
    cout<<endl;
         if (gender == 'm')             // m = male
              cout<< "Sir, what is you name? " <<flush;
         else //f = female output
              cout<< "Madam, what is you name? " <<flush;

    getline(cin, name);
    cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
    cout<<endl;
    cout<< "Your name adds up to " ;
   
    int sum = 0; 
    for(a = 0; a!= name.length( ); ++a)
    { 
      sum += int(name[a]);
    }
    cout<<sum;

this is the program Ive written. If I input just 'm' for the gender and then input a name the sum outputs 0
if I input 'male' then it outputs and then I input a name it outputs a value but its not the correct ascii value.

[Bazzy]

That is because of your extra characters. you should move cin.ignore before getline or call cin.sync (before getline)

[takumi05]

sorry whats "cin.sync"?
I havent learn that yet.

[Bazzy]

It removes the characters you didn't read from the stream buffer

ahhhh okay thank you
