How to define and assign values to arrays in the C language?

In C language, arrays can be defined and assigned values using the following methods:

1. Define an array:
2. [];
3. I am unable to attend the meeting due to a scheduling conflict.

   I cannot go to the meeting because of a conflicting schedule.

4. Define an array of 5 integers.
   Define an array of 10 floating point numbers.
5. Assigning values to array elements.
6. Using index assignment: You can assign a value by specifying the index position of the array. [] = ;

   Example: numbers[0] = 1; // Assigning the value 1 to the first element of the array numbers
   grades[3] = 85.5; // Assigning the value 85.5 to the fourth element of the array grades

7. By using a loop for assigning values: You can use a loop structure to iterate through an array and assign values one by one.
   Example: for (int i = 0; i < 5; i++) { numbers[i] = i + 1; // Assign elements of the array numbers as 1, 2, 3, 4, 5 sequentially }

Please be aware:

1. The array index starts from 0, and you can access array elements using [].
2. The length of an array must be a constant integer, either directly specified or represented through a macro definition or variable. It is incorrect to use a variable to define the length of an array, such as in the statement int length = 5; int numbers[length];.
3. It is possible to assign values to an array while defining it, such as int numbers[5] = {1, 2, 3, 4, 5};, which defines an array of 5 integers and assigns values of 1, 2, 3, 4, and 5 to its elements in order.
