c - Passing multi-dimensional arrays into functions and editing values -


this question has answer here:

i'm working on creating simple wordsearch generator having problem passing 2 dimensional array through function , editing value inside. have declared array in main such:

char tablevalues[xsize-1][ysize-1];

i'm filling each point in array - in main, passing through function fills array random letters , returns.

void filltable(char *tablevalues){     ( int = 0 ; < xsize ; i++ ){         ( int j = 0 ; j < ysize ; j++ ){             if ( tablevalues[i][j]=='-')                 tablevalues[i][j] = "abcdefghijklmnopqrstuvwxyz"[rand () % 26];         }     } }

my problem error gets flagged @ "tablevalues[i][j]" parts, i'm not sure how else i'd edit individual points in array pointers. appreciated, thanks

i calling function as

filltable((char *)tablevalues);

try this,

void filltable(char *tablevalues){ ( int = 0 ; < xsize ; i++ ){     ( int j = 0 ; j < ysize ; j++ ){         if ( *((tablevalues +i*(xsize-1))+j)=='-')             *((tablevalues+i*(xsize-1))+j) = "abcdefghijklmnopqrstuvwxyz"[rand () % 26];     } } }
