How to initialize a two-dimensional array in C++

C Method to initialize a two-dimensional array: first define two integer variables and initialize different values ​​​​for the two-dimensional array; then use a double loop to output each value in the array; finally use curly brackets The enclosed numbers are assigned directly.

C Method to initialize a two-dimensional array:

1 , First, define two integer variables to control the output of the two-dimensional array.

#2. Next, initialize different values ​​​​to the two-dimensional array n[3][4].

#3. Finally, use a double loop to output each value in the array.

4. Two-dimensional arrays can be directly assigned using numbers enclosed in curly brackets. Each pair in the inner curly brackets represents a row, and the value in each pair of inner curly brackets Represents each value in a row (note that the value in curly brackets should correspond to the number of elements in the two-dimensional array).

#5. Run the program and you can see that the values ​​in the two-dimensional array are successfully output.

#6. What will happen if you only assign values ​​to some elements in the two-dimensional array, for example, only assign an initial value to one row?

#7. Run the program and you can see that in the array, only the first row has an initial value set, and the values ​​in other rows are all 0.
