Accessing array of variables

Status
Not open for further replies.
Hello I am working on a project. I am using MicroC pro for PIC microcontroller. I have created, say, 10 arrays-

const char V01 [15]= { some 15 values }
const char V02 [15]= { some 15 values }
.
.
.
const char V10[15]= { some 15 values }

Now I want to access values from V01 to V10. I tried to make another array "VX" of variables V01 to V10. But could not succeed. I am also confused between pointers, array of pointers, addresses, datatype of variable VX etc and how to put in the code.

I also tried-

value = VX [n];

if (some logic) VX = V01;
else if (some logic) VX = V02;
.
.
.
else VX = V10;


Note- 2-D array is not a solution for me.

You are very nearly there.. Create one pointer

const char* VX;

Then point it to the start of each array..

if (some logic) VX = &V01[0];
else if (some logic) VX = &V02[0];
.
.
.
else VX = &V10[0];

Then access like this..

VX[10] = xxx;

Okay!! In C, an array name is essentially a pointer.. So!!

char array[10]; //Set up a variable array..

char * arrayptr = &array[0]; //Point to first location..

Now this statement..
x = array[3];

is exactly the same as

x = arrayptr[3];

if you had another character array..

char array2[10];

you can point to it with the same pointer..
arrayptr = &array2[0];

But the pointer can be moved whereas the array name cannot!
