Definition of a two-dimensional array:

Data type array name [constant expression 1] [constant expression 2] = {...}

int a[2][3] ={

{4,5,6},

{7,8,0}//or {7} does not write after 8 and 9, the system will help you add 0{7,0,0} by default

};

OR:

int b[3][2] ={3,87,43,66,82,11,34};

OR:

int b[][2] ={3,87,43,66,82,11,34}; Horizontal can not write

Array of strings

char array name [number of strings] [maximum allowable value per string] ={....}

Char str[3][15] ={"ipad", "ipod", "iphone"};

A string array is essentially a two-dimensional array that accesses a string using the array name [first-dimensional subscript].

The length of each string cannot exceed the length of the second dimension-1.

For example:

Char str2[3][20] ={"Luoshuailuotingluomama", "ipod", "ipad"};

The second dimension is 20, 20-1 = 19, but the first string is more than 19.

Char str2[3][20] ={"luoshuailuotingluomamadddddddssssssss", "ipod", "ipad"}; will not error, but will be warned.

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

printf ("The End of Result:%s\n", Str2[i]);

}

Consider a question:

Creates an array of strings, pairs of strings (English?) Sort from small to large

Char str[5][15] ={"ipad", "ipod", "iphone", "main", "Luoshuai"};

Char temp[] ={0};

for (int i =0; i < strlen (str); i++) {

for (Int J =0; J<strlen (str)-i-1;j++) {

　　　　　if (strcmp (Str[j] > str[j+1]) > 0) {

Strcopy (Temp,str[j]);

Strcopy (str[j],str[j+1]);

Strcopy (str[j+1],temp);

}

}

}

for (Int J =0; J<strlen (str); j + +) {

printf ("The End of Result:%s\n", str[j]);

}
