Question

C++... How do I separate a C String, entered by a user, by commas? Say they enter Frog,Wolf,Spider... I want a array containing the elements {Frog, Wolf, Spider}

thanks

Here's my idea so far...

cout << "Enter the column names (c of them), each name seperated by a comma" << endl;

char colNames[100];

cin >> colNames;

for (int i = 0; i < 99; ++i){

if (colNames[i] == ','){

//parse the string, assign that string name to that column

}

}

cout << colNames << endl;

# Note -> if you dont know vector please learn it, it will make your life easy w.r.t c++. if you still want me to do it for array please let me know

#include <iostream>
#include <string>
#include <vector>
using namespace std;
int main()
{
   // to store input paragraph
   string paragraph;
   // to store the final word
   vector<string> wordArray;
   // to store temp word
   string word = "";

   // take input
   cout<<"Enter your string : ";
   cin>>paragraph;

   // scan entire input
   for (int i = 0; i < paragraph.length(); ++i)
   {
       // if comma found
       if (paragraph[i] == ',')
       {
           // if word is not empty
           if (word != "")
           {
               // store word and reset it to empty
               wordArray.push_back(word);
               word = "";
           }
       } else {
           // else add new character to word
           word += paragraph[i];
       }
   }
   // for final word -> when no comma at end of paragraph
   if (word != "")
   {
       wordArray.push_back(word);
       word = "";
   }
  
   // print stored word
   cout<<"Output: { ";
   for (int i = 0; i < wordArray.size(); i++) {
cout<<wordArray[i]<<" ";
   }
   cout<<"}"<<endl;
   return 0;
