| choice of two arrays with pointer - how can it be? |
 Posted: Mon Jul 16, 2018 7:08 am |

I would like my program to write the texts in two languages so that I can specify a variable with the variable which is the current language.
The Hungarian and English language texts are stored in a single 'char const' array, and I want to solve the script with a pointer. Unfortunately, I have no practice in the pointer address syntax, so please help me.
I copy a sketch of a program outline here, with question marks for me "dark" parts. (now i'm all pretty "dark").  
I apologize for my weak English knowledge ....
| Code: |
//----definition of variables----
.
.
char char_kiiras1[22]; //display text
int nyelv; // language variable
.
.
.
//----nyelvi konstansok-------
char *muvkiir[32]; // ?? pointer, this is done by making a reference (with an element number)
.
char const muvkiir_hun[32][22] = {{"Hibajelentes"},{"PUTD HIBA!"},{"SETUP vetel HIBA!"},{"Kilep"},…}; // Hungarian text (32-element array)
char const muvkiir_eng[32][22] = {{"Error report"},{"PUTD ERROR"},{"SETUP rec. ERROR!"},{"Exit "},…}; // English text (32-element array)
.
.
.
void main() {
.
//--- Set language texts (nyelv = 0 Hungarian, nyelv = 1 English)---
if(nyelv==0) {
??????;
}
else {
??????;
}
.
.
.
strcpy(char_kiiras1,muvkiir[18]); //preparation of text “Beallitasok” or “Set” (18. element)
.
.
.
glcd_text57(28, 6, char_kiiras1, 1, ON); // Display "Beallitasok" or „Set” text
.
.
}

Others will offer their suggestion..
here's mine
Make ONE 64 element array, where [0] is the 1st msg, in hung and [1] is the 1st msg in eng. repeat 31 more times.
When lang=0, add 0 to the 'msg offset' value. When lang=1, add 1 to the 'msg offset' value.
The msgs are in 'pairs'..same msg, 2 languages, repeated 32 times.
This 'should' work, I think...
Should be easy to try...

| Or just join the two arrays into a single 3 dimensional array. Make the third dimension '0' for the first language and '1' for the second... |

Temtronic, thank you, your suggestion is super, and in any case simpler than the "play with the pointer"
I try to make the 'msg offset' variable simpler to use (elements of the 'muvkiir' array are used in more than 100 locations in the program ...)
Thanks again for the idea!
