To Search an element using sequential search.

Program:
#include<stdio.h>
#include<conio.h>
int Sequentialsearch(int[],int,int);
void main()
{
int x[20],i,n,p,key;
clrscr();
printf("\n Enter the no of element:");
scanf("%d",&n);
printf("\n Enter %d elements:",n);
for(i=0;i<n;i++)
scanf("%d",&x[i]);
printf("\n Enter the element to be search:");
scanf("%d",&key);
p=Sequentialsearch(x,n,key);
if(p==-1)
printf("\n The searchis unsuccessful:\n");
else
printf("\n%d is found at location %d",key,p);
getch();
}
int Sequentialsearch(int a[],int n ,int k)
{
int i;
for(i=0;i<n;i++)
{
if(k==a[i])
return(i);
}
return(-1);
}
