Write a C program to perform linear search on integers

In the previous article I have talked about How to take password from user in C language?  Today i will cover another very important program that is asked many time in engineering.Yes, you have heard about linear search but have implemented it practically?. Let's start by understanding a C program to perform linear search.

Linear search program in exam usually asked in following ways -

- Write a C program to perform linear search on on integers?

- How to pefrom linear search in C program?

So below is the C program to do linear search.

C program to take password from user

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44

#include <stdio.h> #include <conio.h>    void main() {  int array[10];  int i, N, keynum, found=0;     clrscr();     printf("Enter the value of N\n");  scanf("%d",&N);     printf("Enter the elements one by one\n");  for(i=0; i<n ; i++)  {   scanf("%d",&array[i]);  }  printf("Input array is\n");  for(i=0; i<N ; i++)  {   printf("%d\n",array[i]);  }  printf("Enter the element to be searched\n");  scanf("%d", &keynum);     /* Linear search begins */  for ( i=0; i < N ; i++)  {   if( keynum == array[i] )   {    found = 1;    break;   }  }  if ( found == 1)  {   printf("Search operation was successful\n");  }  else  {   printf("Search has failed\n");  } }

Output:

Enter the value of N : 4

Enter the elements one by one 

3

1

6

2

Input array is 3 1 6 2

Enter element to be searched 6

Search operation is successful

I hope you have enjoy the program. I would like to have feedback from you. Your feedback, question ,queries or comments  are always welcome.

Thanks.
