Thread: array question

i'm completely puzzled by a small problem,
i would appreciate it if someone could help
me out.

outside main i have:

const int n = 2;

inside main i have:

float qr;
float y[n];

then, a bit further down, initializing variables:

qr = 0;
y[1] = 1.;
y[2] = 3.;

when i did cout << qr i got 3 ?!
when i didn't include y[2] i got 0 as i wanted. probably i'm
overlooking something with arrays, but i can't seem to figure
out what it is..... anyway thnx ia for helping me out,

Martijn

The index of an array starts with 0 and not with 1.

Code:

qr = 0; 
y[0] = 1.0f; 
y[1] = 3.0f;
