1. Odd compile error in C: creating arrays    stackoverflow.com

I'm trying to figure out what the compiler doesn't like about this:

enum { COLS = 10 };
void process_row( int arr2d[][COLS], int row, int arr[], int pickrow);
...
int a2d[][COLS] = { {1,2,3}, {4,5,6}, ...

2. C Compile-Time assert with constant array    stackoverflow.com

I have a very big constant array that is initialized at compile time.

typedef enum {
VALUE_A, VALUE_B,...,VALUE_GGF
} VALUES;

const int arr[VALUE_GGF+1] = { VALUE_A, VALUE_B, ... ,VALUE_GGF};

3. Compile-time lookup array creation for ANSI-C?    stackoverflow.com

A previous programmer preferred to generate large lookup tables (arrays of constants) to save runtime CPU cycles rather than calculating values on the fly. He did this by creating custom Visual ...

4. Compile-time array concatenation    stackoverflow.com

C supports concatenating constant strings at compile-time. Can I do the same for any constant array? (E.g. concatenate two char ** arrays.)

5. "Swapping" two arrays like this doesn't compile because..    bytes.com

...during the call to swap_arrays the name of the array decays to a pointer to its first element and that pointer is a temporary variable and you cant bind a non-const reference to a temporary. Correct analysis? The code (that only compiles if you comment out the call to swap_arrays()): #include #include using namespace std; void swap_arrays(int *&a1, int ...

6. compile error: new : cannot specify initializer for arrays    bytes.com

The above program is a test program to test how to use vector instead of array for my own project, so the setvalue and displayvalue function is simplied for test purpose (they are actually functions from another library which I cannot change). I want to keep data_t defined as an array of unsigned char. There is a compile error for the ...

9. Compiling whats held in an array    cboard.cprogramming.com

Hi all, I have an unusual request. Does anyone know a way to compile a C program from within another program - when the source code to compile is held in an array. In other words is there a gcc function in the c library, like gcc(source_array, output_array); What I'm trying to avoid is having to put the source code into ...

11. Scanning array compile error    forums.devshed.com

This is my source code. Line 37 is the one that gives me compiling error. If it looks confusing, it's because it's just homework. #include #include void functionTwo (double, double); void functionThree (double, double); void functionFour (double); void functionFive (double); void functionSix (double, double); int main(void) { double arrayOne[18]; double arrayTwo[18]; functionTwo(arrayOne[18], arrayTwo[18]); functionThree(arrayOne[18], arrayTwo[18]); functionFour(arrayOne[18]); functionFour(arrayTwo[18]); functionFive(arrayOne[18]); functionFive(arrayTwo[18]); ...
