These are array of arrays. 2-D character array

consists of strings as its individual elements.Declaration :-

char a[10][10];

Initialization:-char a[10][20]={

// array of strings

void main()

{

const int DAYS = 7; //number

of strings in array

const int MAX = 10;

//maximum size of each string

//array of strings

char star[DAYS][MAX] = {

Sunday, Monday, Tuesday,

Wednesday, Thursday, Friday,
