Want to input a name with comma?

ghadf (7)
Hello everyone?

I want to know if someone can help me to understand how to input a name with comma and how to check if the user input the name with one comma or multiple( can I check it with ispunc function?/)

Thank you much for your help.

you can use the cin.getline() to get everything they type in, but im not sure how you would check for multiple commas

string name;
bool comma = false;
getline(cin,name);
for(int i=0; i<name.length(); i++)
{
     if(name[i] == ',')
       comma = true;
}
if(comma == true)
   cout<<"Name with comma";


please atleast try to code something yourself.

        gets(name);
        fflush(stdin);
        letters=strlen(name);
        valid = true;
            for (int i = 0; i < letters; i++){
                if (isdigit(name[i])){          
                    valid = false;
                    cout << "Sorry!! There should be no digit in the name ";
                    break;

Now I'm trying to get rid of the ' , ' where ever the user inputs it and return the name without any!!! I'm stuck in that part

Here is what I came up with, but doesn't work! :(

 for (int i=0; i < letters; i++){
                   if (name[i]==','){
                       name[i]='/0';
                   }                 
                   name[i]=tolower(name[i]);           
               }
               name[0]= toupper(name[0]);              
               cout<<" this is name"<<name;



(forget about the rest of it) I tried to null it, but it will null everything!! :(

if (name[i]==','){
 name[i]='';

try this.

If it doesn't work, create another string, assign the first string to it and when a comma occurs use continue statement.

ghadf,
You'll run into problems with terminating strings like that. using c-style terminators, you'd lose the second half of the string if you didnt assign it to another variable.

why not use the string functions? here is an example:
