1) a) What would be the output of the program? Run the program with 10 20 30 40.
b) What does the program do?
#include <iostream.h>
main()
{ int table[10] , n = 0, i, nko, upubm;
cout<<" ENTER THE
DATA: " << endl;
while (cin>>
table[n]) {n++;}//while
for(i=0;i<n;i++){ cout << " i is "<<i<<"table[i]="<<table[i]<<endl;}//for
nko = table[0];
for (i
= 1; i<n; i++)
{ if (table[i] < nko)
nko = table [i];
}//for
for (i
= 0; i < n; i++){
upubm = upubm + table[i];
}//for
cout << " THE NKO IS
" << nko << endl;
cout << " THE UPUBM
IS " << upubm << endl;

4)Design a simple database “Grading
System” for Professor Ebrahimi with the following
functions:
append(), display(), search (),
modify(), and delete()
a)
Show
the main menu
b) Show the function insert
c) Show the
function modify.
5) How can the grading system be improved using
different data structures such as arrays and random access files?
What is the problem with modification and
deletion?
a)
Show
the insertion function
b) Show the deletion function
c) Indicate one advantage and
one disadvantage for each method versus the other
6) Declare the user data type called Student using a structure or class.
b) show the
insertion functions fro the above.
c) show the
structure using a linked list
d) Show display fuction
using linked list.
