Program No: 8(D) C Program For Linear Searching in an Array

C program for Linear search in array

Linear Search in C

To search any element present inside the array in C programming using linear search technique, you have to use only one for loop as shown in the following program.

C Programming Code for Linear Search

Following C program first ask to the user to enter the array size then it will ask to enter the array elements, then it will finally ask to enter a number or element to be search in the given array to check whether it is present in the array or not, if it is present then at which position :

Source Code:

/* C Program - Linear Search */
  
#include<stdio.h>
#include<conio.h>
void main()
{
 clrscr();
 int arr[10], i, num, n, c=0, pos;
 printf("Enter the array size : ");
 scanf("%d",&n);
 printf("Enter Array Elements : ");
 for(i=0; i<n; i++)
 {
  scanf("%d",&arr[i]);
 }
 printf("Enter the number to be search : ");
 scanf("%d",&num);
 for(i=0; i<n; i++)
 {
  if(arr[i]==num)
  {
   c=1;
   pos=i+1;
   break;
  }
 }
 if(c==0)
 {
  printf("Number not found..!!");
 }
 else
 {
  printf("%d found at position %d",num, pos);
 }
 getch();
}
