Array Initialization (Section 6.7.8, Paragraph 3)
Array initialization is supported; however, the array size must be
established before initializing individual elements of the array.
The following code, which assigns a single element of an array without
establishing its size, is not supported:
The following initialization, which establishes the array size before
initializing a single element, is supported:
It is also possible to initialize the entire array with a single statement, as
follows:
Delayed Declaration
The C2H Compiler does not support delayed declaration of variables.
For example, the following code, which first declares an array of
unspecified size and later provides the size, is not supported:
You can establish the size of the array when it is declared:
Expressions
The C2H Compiler does not support the following C operators.
Unary Operator (Address Operator) (Section 6.5.3.2, Paragraph 1)
The unary & operator used as an address operator is not supported.
int a[] = {[5]=2};
int a[6]; /* establish array size */
a[5]=2; /* assign element 5 */
int a[6]={0,0,0,0,0,2}; /* init a[]*/
int b[]={0,0,0,0,0,2}; /* init b[]*/
int a[];
int a[20];
int a[20];
