so my program gets the numbers correctly when there are quotes but not otherwise

[lotrsimp12345]

if it contains quote it cuts it out, then i am stuck on part when i just enter in a problemset without a quote or single quote. Then it doesn't gather numbers correctly but stores the entire string

int main()
{


    cout <<"enter the problemset and number""\n";
    //problems represents name and numbers
    string problems , probtitle;
    string xx;
    bool x=true;
    char quote;
    string str1, str2;
    string begin;
    //gather name
    if(cin.peek()=='"' || cin.peek() == '\'')
    {
        cin >>quote;
        getline(cin,problems,quote);
    }
    else
    {
            getline(cin,problems);
    }
cout<<problems;

    //gather problem numbers

    while(x==true)
    {
        if(cin.peek()=='0'||cin.peek()=='1'||cin.peek()=='2'||cin.peek()=='3'||cin.peek()=='4'||cin.peek()=='5'
||cin.peek()=='6'||cin.peek()=='7'||cin.peek()=='8'||cin.peek()=='9'||cin.peek()==','||cin.peek()=='-')
        {
            getline(cin,problems);
        }
        else
        {
            getline(cin,xx);
            if(xx.compare("\n"))
            {
            x=false;
            }
        }
    }
    cout<<problems;

Then it doesn't gather numbers correctly but stores the entire string

That's what you tell it to do with getline(cin,problems) . I can help you fix it by taking the entire line and parsing it, but I need you to describe the format of the problemset. Just showing your code isn't enough.

Why not just read a whole line with getline, then use a utility function which examines the line to see if quotes are present, and if so remove them.

All this peek() stuff is overly complicating things.

[lotrsimp12345]

so my problem is they enter a line of code which contains the problemname which may contain quotes or not.Then have to find the numbers. Say do problems what ever numbers each seperated by a comma and finally state what problem set from. Can't have duplicate numbers and must be ordered.

[lotrsimp12345]

what class is utility function from? can only use string class and c-string class.

[Tom Gunn]

That's more helpful, but a format specification would be better. Show an example of the input and output of the program and explain how the input got to the output.

[lotrsimp12345]

so input could be
"bob"1-5,6-10,11-15,57
or
'bob' 1-6,1-7,9-10
or
bob 1-7,12-18
spaces don't matter after problemset name
output could be
do problems 1,2,3,4,5,6,7,12,13,14,15,16,17,18 of bob. from last example
