Why an error in while (cin >> #variablename#)?

Question

Terminal gives me an error in

while (cin>>value) {.

It says there is no matching for ">> operand".

How to solve it?

Answer 1

You must be using %,& operator. In c++ you can directly use cin>>operand and variable name.

For e.g.

cin>>a,b,c;

I am using c++.
I defined a variable in main function, "value".
I defined a vector where the values the user types are gathered. Now, to have the user insert values I use a while cycle, like this:
while (cin>>value) {
  vector:push_back(value);
}
Anyway, the debugger says there is an error in cin>>value operand... Can't understand why, the exaample you exposed is exactly the situation where I get told there is an error. :(

Vectors in C++ are sequence containers representing arrays that can change in size.
for e.g.
  while(cin >> value[10])
  {
