int a[10],i,n,key,f=0; 
printf("enter the size of array: "); 
scanf("%d",&n);
printf("enter n elements into array: "); 
for(i=0;i<n;i++)
{
scanf("%d",&a[i]);
}
printf("enter the key element to be searched: "); 
scanf("%d",&key);
for(i=0;i<n;i++)
{
if(a[i]==key)
{ 
f=1;
break;
}
}
if(f==1)
printf("the element found");
