One dimensional array in C

One-dimensional arrays in C provide a powerful tool for storing and manipulating sequential data elements of the same type.

 Here's how you can declare, access, and modify elements in a one-dimensional array in C:

Syntax for Declaring a One-Dimensional Array:

datatype arrayName[arraySize];

datatype: Specifies the type of data the array will hold (e.g., int, float, char).

arrayName: The name of the array.

arraySize: The number of elements in the array.

Accessing Elements in a One-Dimensional Array:

You can access individual elements of the array using their index.

Array indexing in C starts from 0.

arrayName[index];

Modifying Elements in a One-Dimensional Array:

To modify an element in the array, simply assign a new value to the desired index.

arrayName[index] = newValue;

Example:

// Program for one dimensionl array in C
#include<stdio.h> 

int main() {
    // Declaration and Initialization
    int numbers[5] = {1, 2, 3, 4, 5};
    
    // Accessing and Printing Elements
    printf("Elements of the array: ");
    for(int i = 0; i < 5; i++) {
        printf("%d ", numbers[i]);
    }
    
    // Modifying an Element
    numbers[2] = 10;
    printf("\nArray after modification: ");
    for(int i = 0; i < 5; i++) {
        printf("%d ", numbers[i]);
    }
    
    return 0;
}

Output:

Elements of the array: 1 2 3 4 5 
Array after modification: 1 2 10 4 5 

In this program:

We access and print all elements of the array.

We modify the element at index 2.

Finally, we print the modified array.
