Two-Dimensional or 2 d character array in C programming

One-dimensional array is fine to store a single string, but to store a number of strings we have to declare two-dimensional character type array. The declaration is simply like 2 d integer type array. Suppose we want to store the name of the months in a character array. We have twelve months in a year and the length of ‘september’ is maximum-9. So the array should be char month[12][10].The first index indicates the number of string to be stored and the second index indicates the number of locations for each string. While storing string in 2 d array we have to mention the first index.

This C program will take the name of the months from the user, store them in 2d array  and the month names will de displayed in upper case.

#include< stdio.h >

#include< string.h >

void main()

{

char month[12][10];

int i,j;

clrscr();

for(i=0;i< 12;i++)

{

printf("Enter the month name:-");

scanf("%s",&month[i]);

}

printf("Month names are:-\n");

for(i=0;i< 12;i++)

{

j=0;

while(month[i][j]!='\0')

{

printf("%c",toupper(month[i][j]));

j++;

}

printf("\n");

}

getch();
