Inputting Array Elements in C

To input array elements in C, you can follow these steps:

  1. Declare an array variable of the desired data type and size. For example, to declare an array of integers with a size of 5, you can use the following code: c int arr[5];

  2. Use a loop or individual statements to input the elements of the array. You can use the scanf function to read input from the user. For example, to input elements into the array using a loop, you can use the following code: c int i; for (i = 0; i < 5; i++) { printf("Enter element %d: ", i); scanf("%d", &arr[i]); }

In this code, the loop iterates from 0 to 4 (inclusive) and prompts the user to enter the value for each element. The scanf function reads the input and stores it in the corresponding array element using the & operator.

  1. After inputting the elements, you can access and use them in your program as needed. For example, you can print the elements of the array using a loop: c printf("Array elements: "); for (i = 0; i < 5; i++) { printf("%d ", arr[i]); }

This code will print the elements of the array separated by spaces.

  1. Remember to include the necessary header file at the beginning of your program. For array input/output, you need to include the <stdio.h> header file.

That's it! These steps allow you to input array elements in C.
