/* Main Function*/

void main( )

{

int n, el, m[200];

number = input(m, n,el);

el = search;

printf("\n Entered list: \n");

display(m, n);

linear_search(m, n, el);

printf("\n In the following list\n");

display(m, n);

}

Program 1 examines each key value in the array 'm', one by one and stops while a match occurs or the entire array is searched.
