qsort.c error

[jwzumwalt]

C does not allow a variable to define an array size. For example, in line 10-11 of qsort.c it shows...
int size = 5;
int a[size] = {5, 4, 1, 3, 2}; // This creates an error.

Main.c:11:4: error: variable-sized object may not be initialized
11 | int a[size] = {5, 4, 1, 3, 2};

instead, use
#define size 5
int a[size] = {5, 4, 1, 3, 2};
