element=liner (a,searchkey,arraysize);
if (element!=-1)
cout<<"::::Found value in index \n"<<element<<"\n";
else
cout<<"::::value not found :::::\n";
}
int liner(int array[], int key ,int size){
int index=-1;
for(int n=0;n<size;n++)
if (array[n]==key)
index =n;
return index;
}is this code true .
i search about the value .and return its index
but how i can input index and return its value
