The application of two-dimensional array

Two-dimensional arrays: two-dimensional arrays can be thought of as row-based, one-dimensional arrays.

Example: a[3][3]={{1,2,3},{4,5,6}.{ 7,8,9}} can be seen as being that the array is made up of three elements, each of which includes a one-dimensional array of three numbers.

1. Initialization of two-dimensional arrays

#include <stdio.h>

int main ()

{int p[3][3]={{1,2,3},{4,5,6},{7,8,9}};

int i=0,j=0;

for (i=0;i<3;i++)

{for (j=0;j<3;j++)

{printf ("%d", p[i][j]);

}

printf ("\ n");

}

return 0;}

2. Two-dimensional arrays as function parameters: two-dimensional arrays as function parameters, pass the address, the array of the two-dimensional array is an argument, representing the first element (including three data) of the first address.

#include <stdio.h>

void My_find (int (*p) [3])

{int i=0,j=0;

for (i=0;i<3;i++)

{for (j=0;j<3;j++)

{printf ("%d", p[i][j]);

}

printf ("\ n");

}

}

int main ()

{int p[3][3]={{1,2,3},{4,5,6},{7,8,9}};

My_find (P);

return 0;

}
