When you use scanf() you must give a pointer to it. When you use scanf("%d", a[i]+1) it means that you are using 1-based indexing, So the your string is starting from index 1(not 0).
Can I do the same with strings, what I mean is:
string st; cin >> (st + 1);
I know it is does not work but is there any way to do this?
you can do:
string st;
cin >> st;
st = ((string)" ") + st;
Thanks
Can u tell after I perform certain operations, now I want to print original string without initial space given at beginning. What I would do then?
st.erese (st.begin ())
