Error when declaring a vector in a function in C

I simply try to define a vector named numlist in the function createlist but the errors I get are:

expected constant expression
cannot allocate an array of constant size 0
'numlist' : unknown size
'numlist' undeclared identifier

its just this line in the function

int langd=3;
int numlist[langd];

You are using a c89 compiler, variable length array is a c99 feature.

To fix your program, use a constant:

#define LANGD  3

int langd = LANGD;
int numlist[LANGD];
