vectors basic doubt

[ryllprous]

I have a code which defines a vector as

unsigned int nx=37;
vector <unsigned> nNodes (1,nx);

Does this mean that nNodes is a vector of 1 position with value=37 (37) or that nNodes is a vector of 2 positions with values 1 and 37 (1,37)

Thanks,


Ramon

It means that nNodes has one element with the value 37.

One day you will also be able to read the reference pages. ;)

EDIT: If you want the vector to contain 2 elements with the values 1 and 37 you can use curly brackets instead.

unsigned int nx=37;
vector <unsigned> nNodes {1, nx};
