Question

https://code.sololearn.com/c5Mu93LXxeu1/?ref=app
I try to split string with delimeter and I try it with string array. But something is not correct. Need your help.

Answer 1

a1 is an array there, not string..

You can print array size by using
cout << (sizeof(a1) /sizeof(a1[0])) ;

Answer 2

Yes, but I want to split string a into chunks. Or how to do it. Why it is not possible with a1.size()?

Answer 3

a1 is an array and array don't have a method size().
You are splitting string 'a' into length 6 string in array a1, check this by
cout<< a1[b-1] << endl;
inside outer loop.. After end of inner loop.

and size can determined by above previouly posted formula.

Answer 4

What is the goal of the code? how you'd like to split the string, and how the expected result should be?
