Using Arrays in C

To use arrays in C, follow these steps:

Step 1: Declare an Array - Start by declaring an array variable, specifying the data type of the elements and the size of the array. - For example, to declare an array of integers named numbers with a size of 5, you would write: int numbers[5];

Step 2: Initialize the Array (Optional) - You can initialize the array with initial values at the time of declaration. - For example, to initialize the numbers array with values 1, 2, 3, 4, and 5, you would write: int numbers[5] = {1, 2, 3, 4, 5};

Step 3: Access Array Elements - You can access individual elements of the array using their index. - Array indices start from 0, so the first element is at index 0, the second element is at index 1, and so on. - To access the third element of the numbers array, you would write: int thirdNumber = numbers[2];

Step 4: Modify Array Elements - You can modify the value of an array element by assigning a new value to it. - For example, to change the value of the second element of the numbers array to 10, you would write: numbers[1] = 10;

Step 5: Use Loops for Array Operations - Loops are commonly used to perform operations on arrays, such as iterating over all elements or performing calculations. - For example, you can use a for loop to print all elements of the numbers array: for (int i = 0; i < 5; i++) { printf("%d ", numbers[i]); }

That's it! You have now learned the basic steps to use arrays in C.
