C 2D Array Assignment Guide

When assigning values to a two-dimensional array, it is important to keep in mind the following points:

1. Index order: A two-dimensional array is an array composed of multiple one-dimensional arrays, with each one-dimensional array representing a row or column of the two-dimensional array. When assigning values to a two-dimensional array, it is necessary to assign values to each element in accordance with the index order of the two-dimensional array.
2. Element type: Each element in a two-dimensional array should be of the same data type, so when assigning values, make sure the given value type matches the element type of the array.
3. Array size: When declaring a two-dimensional array, the number of rows and columns must be specified. Assigning values outside of the specified size range will result in an array index out of bounds error.
4. By using loops: Since a two-dimensional array is an array of arrays, it is typically necessary to use nested loops to iterate through each element sequentially and perform assignment operations.
5. Initialization: Two-dimensional arrays can be assigned initial values either by using initialization lists or by assigning values one by one using a loop structure.

In conclusion, when assigning values to a two-dimensional array, it is important to follow the above points to ensure the assignment operation is correct and error-free.
