Difference between while and do while

NIELIT O Level January 2016 Solve paper

Q 7 b.(ii) while and do..while loops

Iteration statements allow the set of instructions to execute repeatedly till the condition doesn’t turn out false. The Iteration statements in C for while loop and do while loop. These statements are commonly called loops. Here, the main difference between a while loop and do while loop is that while loop check condition before iteration of the loop, whereas do-while loop, checks the condition after the execution of the statements inside the loop.

BASIS FOR COMPARISON	WHILE	DO-WHILE
Syntax	while ( condition) { statements; //body of loop }	do{ . statements; // body of loop. . } while( Condition );
Controlling Condition	In 'while' loop the controlling condition appears at the start of the loop.	In 'do-while' loop the controlling condition appears at the end of the loop.
Iterations	The iterations do not occur if, the condition at the first iteration, appears false.	The iteration occurs at least once even if the condition is false at the first iteration.

Passing array to function call by reference

NIELIT O Level January-16 

Q 7 (a) . How does passing an array as an argument to a function differ from call by value?

Solution : 

An array is a collection of similar data type which occupies continuous location on memory. Name of array is constant pointer which point (store address of first element of array) first element. When we passed an array to a function as an argument then we pass address of first element and if any change made inside of function to passing array then its effect original location because it is call by reference.

So when an array is passed to a function as an argument then it’s always being pass by reference.

Differentiate between if and switch case

NIELIT O Level January-2016

Q 6 B (i) :  Differentiate between  if and switch case

Solution : 

While programming, a number conditions come and a number of decisions need to be taken by a programmer. For decision making in C programming, the statements such as if, if..else, else if, switch case etc.

Though which when number of possible condition got increase in some scenario then if-else ladder implementation become complicated. So we can achieve this using switch case in simple manner with decreasing complexity.

1. If the primal Linear Programming problem has unbounded solution, then it’s dual problem will have

(A) feasible solution

(B) alternative solution

(C) no feasible solution at all

(D) no bounded solution at all
Answer C
Explanation :-
If the Primal problem is feasible, but unbounded in the direction of optimisation, then the dual has no feasible solution. Otherwise, if the Primal problem has an optimal solution, then the dual has also an optimal solution.

So the answer for your question is that feasibility of the Primal problem does not imply optimality for the Dual problem. It just excludes the possibility that the Dual will be unbounded in the direction of optimisation.
