Question

(1) Prompt the user for a string that contains two strings separated by a comma. (1 pt)

• Examples of strings that can be accepted:
  • Jill, Allen
  • Jill , Allen
  • Jill,Allen

Ex:

Enter input string:
Jill, Allen

(2) Print an error message if the input string does not contain a comma. Continue to prompt until a valid string is entered. Note: If the input contains a comma, then assume that the input also contains two strings. (2 pts)

Ex:

Enter input string:
Jill Allen
Error: No comma in string.

Enter input string:
Jill, Allen

(3) Extract the two words from the input string and remove any spaces. Store the strings in two separate variables and output the strings. (2 pts)

Ex:

Enter input string:
Jill, Allen
First word: Jill
Second word: Allen

(4) Using a loop, extend the program to handle multiple lines of input. Continue until the user enters q to quit. (2 pts)

Ex:

Enter input string:
Jill, Allen
First word: Jill
Second word: Allen

Enter input string:
Golden , Monkey
First word: Golden
Second word: Monkey

Enter input string:
Washington,DC
First word: Washington

    //loop until input is true
    while(true){
        //ask for input

        getline(cin, str);   //get input
        if(str=="q") //if user type q then break and quit
            break;
        int pos = str.find(","); //check for comma(,) in between words
        if(pos==string::npos) //if no comman found then print error
            cout<<"Error: No comma in string."<<endl;
        else{
            word1 = str.substr(0, pos); //position for the first strings
            word2 = str.substr(pos+1);   //position for the Second strings
            int i=0;
            while(word1[i]==' ')
                word1 = word1.substr(1);
            i=word1.size()-1;
            while(word1[i]==' ')
                word1 = word1.substr(0, i);
            i=0;
            while(word2[i]==' ')
                word2 = word2.substr(1);
            i=word2.size()-1;
            while(word2[i]==' ')
                word2 = word2.substr(0, i);
                //print
            cout<<"First word: "<<word1<<endl;
            cout<<"Second word: "<<word2<<endl;
        }
        cout<<endl;
    }      
    return 0;
}
