Two-dimensional character arrays

Two-dimensional character arrays

A string is an array of characters; hence, an array of strings is an array of arrays of characters. Of course, the utmost size is that the same for all the strings stored during a two-dimensional array.

Declaration:

Syntax

char varname[size][size];

Example:

char a[5][10];

here a is character array which stores 5 strings and every string of length 10 characters.

Initialization of strings:

(i) Static initialization

 char a[5][5]={“cse”,”ece”,”eee”,”eie”,”it”};

(ii) Dynamic initialization

char a[5][10];

Example Program:

C program to print 5 strings.

#include<stdio.h>
#include<string.h>
main()
{
char a[5][10]={"ece","cse","eie","eee","it"};
int i;
printf("given strings are\n");
for(i=0;i<5;i++)
printf("%s\n",a[i]);
}

Output:

Example Program:

Write a C program to read and print n strings.

#include<stdio.h>
main()
{
char a[5][10];
int i,n;
printf("enter no of strings");
scanf("%d",&n);
printf("enter %d strings:\n",n);
for(i=0;i<n;i++)
scanf("%s",a[i]);
printf("given strings are\n");
for(i=0;i<n;i++)
{
printf("%s\n",a[i]);
}
}

Output:
