2 1. WRITE A PROGRAM TO TRAVERSING OF AN ARRAY. #include <iostream.h> # include <conio.h> void main () int a [10], lb = 1, ub, k, I; cout<< ENTER THE SIZE OF AN ARRAY: : ; cin>>ub; cout<< ENTER THE ELEMENTS OF AN ARRAY: ; for(lb=1;lb<=ub;lb++) cin>>a[lb]; cout<< TRAVERSED ELEMENTS ARE: ; for lb=1;lb<=ub;lb++) cout<<a[lb]<< \n ; getche(); OUTPUT ENTER THE SIZE OF AN ARRAY:5 ENTER THE ELEMENTS OF AN ARRAY: TRAVERSEED ELEMENTS ARE:

3 2.
