One-Dimensional Arrays

• A one-dimensional array in C contains a series of elements of the same datatype.
• The elements are zero-indexed, meaning the first element is in position or index 0, and the last element is in position or index (array size) - 1.

Declaration of one dimensional array

• To declare a one-dimensional array in C, you specify the data type of the elements and the name of the array followed by the size of the array in square brackets.
• Here's a basic example:
Program.c
#include <stdio.h> int main() { // Declare an integer array with a size of 5 int numbers[5]; // You can also declare and initialize the array at the same time // For example, initializing an array of integers with specific values int initializedArray[5] = {1, 2, 3, 4, 5}; return 0; }
• In the above example, numbers is an integer array with a size of 5, and initializedArray is another integer array initialized with specific values.
• Remember that the size of the array determines how many elements it can store.
• The indices of the array range from 0 to size-1.
