Two Dimensional Character Array

Two Dimensional Character Arrays

Two-d character arrays are used to create an array of strings. Manipulating a two-d character array is slightly different from manipulating an integer or float two-d array.This is because a character two-d array is likely to be accessed in terms of strings rather than elements, and hence requires only the row subscript . Individual elements can be accessed as usual by specifying both subscripts.

Consider the following example:

#include <stdio.h>

char books[][40] = {

"The Design and Analysis of Algorithms",

"Computer Architecture",

"Prabability and Queuing Theory",

"Operating Systems",

"Analog and Digital Communication",

"Visual Programming"

};

main()

{

int num;

printf ("\nEnter a semester number (between 1-6)");

scanf("%d",&num);

if ( num>=1 && num<=6 )

{

    num--;

/* To account for subscripting from zero */

    printf ("Your book for this semester is %s ", books[num]);

              /* note the usage of row index to specify the string */

  }

else

    printf("Wrong semester");

}
