(a) Write a macro to find out whether the given character is lower case or not. 7 #include <stdio.h> //#define IS_UPPER_CASE(n) ((n) >= ‘A’ && (n) <= ‘Z’) #define IS_LOWER_CASE(n) ((n) >= ‘a’ && (n) <= ‘z’)… Read More »

Design and draw a 3 x 8 decoder using NOT gates and AND gates and explain its working. 8m Jun2007

Decoder converts one type of coded information to another form. A decoder has ‘n’ inputs and an enable line (a sort of selection line) and 2n output lines. Let us see diagram of 3×8 decoder which decodes a 3 bit information and there is only one output line which gets the value 1 or in… Read More »

An interactive C program to check whether given two numbers are amicable numbers or not

Amicable numbers are two numbers so related that the sum of the proper divisors of the one is equal to the other, unity being considered as a proper divisor but not the number itself. Let’s identify variables needed for this program. First two variables will be the one which will save the values entered by… Read More »

An interactive C program to check whether a given number is a perfect number or not

A positive number is called Perfect Number if it is equal to the sum of all of its positive divisors,  excluding number itself. Let’s identify variables needed for this program. First variable will be the one which will save the value entered by the user and it will be NUM. Second variable will be i… Read More »
