How to use Two-Dimensional arrays and pointers
Use Two-Dimensional arrays and pointers
#include <stdio.h>
/* ww w. ja va 2 s . c o m*/
int main(void)
{
char board[3][3] = {
{'1','2','3'},
{'4','5','6'},
{'7','8','9'}
};
printf("address of board : %p\n", board);
printf("address of board[0][0] : %p\n", &board[0][0]);
printf("but what is in board[0] : %p\n", board[0]);
return 0;
}
The code above generates the following result.
Pointer of pointer
#include <stdio.h>
/*from w w w .j a v a2 s.c o m*/
int main(void)
{
char board[3][3] = {
{'1','2','3'},
{'4','5','6'},
{'7','8','9'}
};
printf("value of board[0][0] : %c\n", board[0][0]);
printf("value of *board[0] : %c\n", *board[0]);
printf("value of **board : %c\n", **board);
return 0;
}
The code above generates the following result.
Loop through an array by using its name as pointer.
#include <stdio.h>
//from w w w . j av a 2 s . c om
int main(void)
{
char board[3][3] = {
{'1','2','3'},
{'4','5','6'},
{'7','8','9'}
};
int i;
for(i = 0; i < 9; i++)
printf(" board: %c\n", *(*board + i));
return 0;
}
The code above generates the following result.
