Linear search using array in C

Linear Search :

It is simplest form of searching of a item in a array. let suppose we have an “array arr “.

arr[6] = { 1, 3, 4, 5, 6, 7 };

  and want to search an “element item ” in our array arr.

item = 5 ;

here we check for each element of array that where it exists.

let see how to do it through program.

#include<stdio.h>
 #include<conio.h>

void main(){
 int arr[6], i, item, pos = -1;
 clrscr();

printf("Enter an array");

for(i = 0; i<6; i++){
 scanf("%d",&arr[i]);
 }

printf("please enter no to search");
 scanf("%d", &item);

  for(i=0 ; i<6 ;i++){
    if(item ==arr[i]){
      pos = i+1;
      break;
      }
  }

  if(pos == -1){
   printf("Element not found");
  }
  else{
    printf("element found on position at : %d",pos);
  }
 getch();

}

 

output :
