What are the methods of initializing one-dimensional ar…

There are several ways to initialize a one-dimensional array in the C language.

  1. Static initialization: assigning initial values to an array at the time of declaration. For example:
  2. Create an array named arr with five elements: 1, 2, 3, 4, 5.
  3. Dynamic initialization: after defining an array, assigning initial values to array elements through a loop or assignment statement. For instance:
  4. Create an array called arr with five elements, and assign each element the value of its index plus one.
  5. Partial initialization: it is possible to only initialize certain elements of the array, with any uninitialized elements automatically initialized to zero. For example:
  6. int arr[5] = {1, 2}; // arr[0] and arr[1] are 1 and 2 respectively, and arr[2], arr[3], arr[4] are automatically initialized to 0.
  7. Initialize an array using the memset() function: This function can set all elements of the array to a specified value, for example:
  8. Initialize all elements of array ‘arr’ to 0 using memset function.

In C language, the values of local array elements that are not explicitly initialized are undefined, they could be any value. Therefore, it is best to initialize the array when defining it.
