get object from vector iterator

[slenkar]

i have a class called block with 2 floats x and y.


i am iterating through a vector called 'block_array'

how do I get the x value of each object in the vector?

I am using this code to iterate:
for (std::vector<block>::iterator it = block_array.begin(); it!=block_array.end(); ++it) {


how do I print out each x value of each object in the vector?

Dereference it. It's just like a pointer.

i tried *it.x but it said iterator didnt have a member 'x'

the . operator works before the * operator does. You'd have to do either (*it).x, or its equivalent. it->x.
