post  how do I add this together?

takumi05 (18)   Link to this post
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

string name;

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?

i get 0 for the ASCII value output

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

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().

I need to for some reason...

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

   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.

That is because of your extra characters. you should move cin.ignore before getline or call cin.sync (before getline)
takumi05 (18)   Link to this post
sorry whats "cin.sync"?
I havent learn that yet.
Bazzy (4111)   Link to this post
It removes the characters you didn't read from the stream buffer
