Explain the characteristics and operation methods of arrays in C language

An array is a homogeneous sequential collection of data items on a single variable name.

For example, int Student[30];

Here, student is an array name containing a collection of 30 data items with a single variable name.

Features

The characteristics of arrays are as follows -

• Arrays are always stored in contiguous memory locations.

• It can store multiple values ​​of similar type that can be referenced with a single name.

• The pointer points to the first of the memory block position, which is assigned to Array name.

• Arrays can be integer, character, or floating-point data types and can only be initialized during declaration.

• Specific elements of an array can be modified individually without changing

• All elements in the array can be distinguished by their index number.

Operations h2>

Operations on arrays include -

• Search - Used to find whether a specific element To exist or not.

• Sort - Helps to sort the elements in an array in ascending or descending order.

Traverse - Process each element in the array sequentially.

• Insert - Helps to insert elements in an array.

• Delete - Helps to delete elements from an array.

Sample Program

The following is a C program for searching for elements in an array -

Real-time Demonstration

#include <stdio.h>
#define MAX 100 // Maximum array size
int main(){
   int array[MAX];
   int size, i, search, found;
   printf("Enter size of array: ");
   scanf("%d", &size);
   printf("Enter elements in array: ");
   for(i=0; i<size; i++){
      scanf("%d", &array[i]);
   }
   printf("</p><p>Enter element to search: ");
   scanf("%d", &search);
   found = 0;
   for(i=0; i<size; i++){
      if(array[i] == search){
         found = 1;
         break;
      }
   }
   if(found == 1){
      printf("</p><p>%d is found at position %d", search, i + 1);
   } else {
      printf("</p><p>%d is not found in the array", search);
   }
   return 0;
}

Output

The output is as follows-

Enter size of array: 5
Enter elements in array: 11 24 13 12 45
Enter element to search: 13
13 found at position 3found
