## What do you understand by a decision-control statement? Give an example of each. 8m Jun 2010

What do you understand by a decision-control statement? Give an example of each. 8 In a C program, a decision causes a one-time jump to a different part of the program, depending on the value of an expression. Decisions in C can be made in several ways. The most important is with the if…else statement,… Read More »

## Explain the difference between a top-down approach and a bottom-up approach in programming. 5m Jun 2010

Explain the difference between a top-down approach and a bottom-up approach in programming. 5m Jun 2010   Top-down Approach Bottom-up Approach A top-down approach is essentially the breaking down of a program to gain insight into its compositional small program (or module) in a reverse engineering fashion. A bottom-up approach is the piecing together of… Read More »

## Explain the concept of array of pointers. 5m Jun 2010

Explain the concept of array of pointers. Using pointers write a program to test whether the given string is a palindrome or not. 10   ARRAY OF POINTERS The way there can be an array of integers, or an array of float numbers, similarly, there can be array of pointers too. Since a pointer contains… Read More »

## What are the precautions that must be taken care to use macros in ‘C’? 5m Dec 2009

What are the precautions that must be taken care to use macros in ‘C’?   Caution in using macros You should be very careful in using Macros. In particular the textual substitution means that arithmetic expressions are liable to be corrupted by the order of evaluation rules (precedence rules). Here is an example of a… Read More »
