Input 10 unequal strings in the main function, use another function to sort them, and then the main function outputs these 10 sorted strings!

Use a pointer pointing to a one-dimensional array as a function parameter.

# Include <stdio. h>
# Include <string. h>
Int main ()
{
Void sort (char (* s) [6]); // a one-dimensional array pointer as a function parameter
Int I;
Char STR [10] [6];
Char (* P) [6]; // defines the pointer of a one-dimensional array as a function parameter.
Printf ("Please input string:/N ");
For (I = 0; I <10; I ++)
Scanf ("% s", & STR [I]);
P = STR; // assign the STR one-dimensional array pointer to P;
Sort (P );
Printf ("the output sequence:/N ");
For (I = 0; I <10; I ++)
Printf ("% s/n", STR [I]);
Return 0;
}
Void sort (char (* s) [6]) // calls a pointer to a one-dimensional array as a function parameter;
{
Int I, J;
Char temp [6], * t;
T = temp;
For (I = 0; I <9; I ++) // I should be smaller than 9; if it is smaller than 10, it is compared 9 + 1; according to the bubble rule,
For (j = 0; j <9-I; j ++) // nine times are required for the first comparison, that is, nine times from I = 0 to I = 8; eight times are required for the second comparison; and so on;
If (strcmp (s [J], s [J + 1])> 0)
{
Strcpy (t, s [J]);
Strcpy (s [J], s [J + 1]);
Strcpy (s [J + 1], t );
}
