general
1

what is the way to dynamically initialize a 2-D array in c

or how could i handle an array of size ar[1000][20000];

plz help me with an example

i would say it depends on what value you want to initialize your array with.

if it’s 0, you could maybe simply bzero(ar, sizeof(ar)), right ?

did i properly understand your question ?

Do you know how to use malloc in general? If so, use it…

char** c2d = (char**)malloc( ... );
for ( int i = 0; i < n; ++i ) {
    c2d[i] = (char*)malloc( ... );
}
