"Learning note", "C language" string array

1. Use Cases
* One-dimensional character array holds a string, such as a name char name[20] = "MJ"
* If you want to store multiple strings, such as the names of all students in a class, you need a two-dimensional character array, char names[15][20] can hold 15 students ' names (assuming the name does not exceed 20 characters)
* If you want to store two classes of student names, then you can use a three-dimensional character array Char names[2][15][20]

2. Initialization
Char Names[2][10] = {{' J ', ' a ', ' y ', ' \ n '}, {' J ', ' I ', ' m ', '/'}};
Char Names2[2][10] = {{"Jay"}, {"Jim"}};
Char names3[2][10] = {"Jay", "Jim"};

3. Code
