Simply by sending the base address from main() and catching that in a pointer in the pointer.
void main()
{ int a[20];
sort(a);
}
void fun(int *p)
{
}
The size of a function can be determined from the size of the array. Arrays and functions are both used in computer programming.
That depends on where you define them. Arrays defined inside functions are declared on the stack (like other variables defined in functions). Arrays defined outside of any function, or using the static keyword inside a function are allocated in the static data area of the program. Other arrays may be allocated using malloc() (or "new" in C++); these are allocated on the heap.
Function arrays are nothing more than arrays of function pointers so, besides the stddef header, you don't really need any libraries to implement a function array unless those functions use a type that isn't available in stddef. #include<stddef.h> void func_1() {} // obviously you must provide void func_2() {} // implementations for these void func_3() {} // functions // a function array void (*function_array[])() = { func_1, func_2, func_3 }; int main() { for(unsigned i=0; i<3; ++i) function_array[i]; // call the function }
You don't need to use ampersand for arrays; it's entirely optional even for strings (character arrays). This is because arrays will implicitly convert to a pointer at the slightest provocation. Thus for an array named X, you can either pass the array to a function as X, &X or &X[0], they all refer to the exact same address.
for arrays you can list the different arrays and what attributes that you give to them.
You cannot sort arrays by other arrays; that wouldn't make sense, anyway.
Arrays
The size of a function can be determined from the size of the array. Arrays and functions are both used in computer programming.
By using the library function #define A[] we can define the size of arrays

To generate a numpy cartesian product in Python, you can use the numpy.meshgrid() function. This function takes in multiple arrays and returns a meshgrid of all possible combinations of the input arrays.
The inherit function `array_dif($arrayOne, $arrayTwo, $arrayThree, ...)` is likely what you're looking for. It compares two or more arrays, and returns an array of values that are unique among the arrays.
Function arrays are nothing more than arrays of function pointers so, besides the stddef header, you don't really need any libraries to implement a function array unless those functions use a type that isn't available in stddef. #include<stddef.h> void func_1() {} // obviously you must provide void func_2() {} // implementations for these void func_3() {} // functions // a function array void (*function_array[])() = { func_1, func_2, func_3 }; int main() { for(unsigned i=0; i<3; ++i) function_array[i]; // call the function }

Thus for an array named X, you can either pass the array to a function as X, &X or &X[0], they all refer to the exact same address.
if you were to call a function you would write it as: function(array[][], int pretend, double pretend2); arrays will always be passed by reference, not by value.
Arrays having more than one dimension is known as multi-dimensional arrays. Multi-dimensional arrays is also known as arrays-of-arrays.
