Search an element in array using linear search


Write a C Program to search an element in an array using linear search.¬†Here’s simple Program to search an element in an array using linear search in C Programming Language.


What is an Array ?


Arrays a kind of data structure that can store a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.

Instead of declaring individual variables, such as number0, number1, …, and number99, you declare one array variable such as numbers and use numbers[0], numbers[1], and …, numbers[99] to represent individual variables. A specific element in an array is accessed by an index.

All arrays consist of contiguous memory locations. The lowest address corresponds to the first element and the highest address to the last element.


Here is source code of the C Program to search an element in an array using linear search. The C program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.


SOURCE CODE : :


/* C Program to search an element in an array using linear search  */

#include<stdio.h>

int main(){
	int a[10],i,n,m,c=0;
	printf("Enter the size of an array :: ");
	scanf("%d",&n);
	printf("\nEnter the elements of the array :: \n");
	for(i=0;i<=n-1;i++)
    {
        printf("\nEnter %d element of an array :: ",i+1);
        scanf("%d",&a[i]);
    }

	printf("\nEnter the number to be search :: ");
	scanf("%d",&m);
	for(i=0;i<=n-1;i++){
		if(a[i]==m){
			c=1;
			break;
		}
	}
	if(c==0)
		printf("\nThe number is not in the list");
	else
		printf("\nThe number is found in the array ");
	return 0;
}

OUTPUT : :


/* C Program to search an element in an array using linear search  */

Enter the size of an array :: 8

Enter the elements of the array ::

Enter 1 element of an array :: 1

Enter 2 element of an array :: 2

Enter 3 element of an array :: 3

Enter 4 element of an array :: 4

Enter 5 element of an array :: 5

Enter 6 element of an array :: 6

Enter 7 element of an array :: 7

Enter 8 element of an array :: 8

Enter the number to be search :: 5

The number is found in the array
