if(stat("seek.pc.db", &files) ==0 )
sizes=files.st_size;
sizes=sizes/sizeof(int);
int s[sizes];
I am compiling this in Visual Studio 2008 and I am getting the following error: error C2057: expected constant expression error C2466: cannot allocate an array of constant size 0.
I tried using vector s[sizes] but of no avail. What am I doing wrong?
Thanks!
Size of an array must be a compile time constant. However, C99 supports variable length arrays. So instead for your code to work on your environment, if the size of the array is known at run-time then -
int *s = malloc(sizes);
// ....
free s;
Regarding the error message:
int a[5];
// ^ 5 is a constant expression
int b = 10;
int aa[b];
// ^ b is a variable. So, it's value can differ at some other point.
const int size = 5;
int aaa[size]; // size is constant.
