I want to give the variable X some values, let's say: 1,2,3
Then I want to check if X has the value 2 or not?
Is it possible? How can write it?
Thanks!

an integer/double/float variable can store only one value at a time.
say if you do this
int x=0;
x=1;
x=2;
cout<<x;
you will get 2 as an output.
to store multiple values you can use array.
ie.
int x[3];
x[0]=1;
x[1]=2;
x[2]=3;

you can use arrays, std::arays, std::vectors, std::deques, std::lists, std::forward_lists, std::basic_strings, std::valarrays, or std::tuples.

Thanks guys, I guess I should start study arrays now!

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
#include <iostream>
int main()
{
int x[3];
x[0] = 1;
x[1] = 2;
x[2] = 3;
for (int i = 0; i < 3; i++)
{
if (x[i] = 1)
std::cout << "array of ints, x, is int value 1 at array index [" << i << "]" << std::endl;
}
return 0;
}
