How would you justify the use of PM software for a medium size project to a mega project? Solution The advantages of a PM software are: The disadvantages are: So For Mega project: The benefits are much more and all the points are valid For Medium project Except for point no 6, 7 and 8 , where the benefits are not huge all other are fully valid and it makes sense to take up a PM software For small scale project: The benefits are shadowed by the cost factor and the coordination is easier offline coordination..

1. I want a java program that can convert a number of base 10 into its corresponding hexadecmial
char? for example it would convert 51966 to CAFE.
Solution
DecimalToHexadecimal.java
import java.util.Scanner;
public class DecimalToHexadecimal {
public static void main(String[] args) {
//Declaring variables
int decimal_no;
//Scanner object is used to get the inputs entered by the user
Scanner sc=new Scanner(System.in);
//Getting the decimal number entered by the user
System.out.print("Enter a decimal number :");
decimal_no=sc.nextInt();
toHexadecimal(decimal_no);
}
//This method will convert decimal to hexadecimal form
private static void toHexadecimal(int decimal_num)
{
int i=0;
//Declaring variables
int rem,quotient;
char hex_num[]=new char[50];
/* Assigning the user entered
* decimal number to quotient
*/
quotient=decimal_num;
/* Checking whether the quotient
* is equal to zero or not

2. */
while(quotient!=0)
{
/* Finding the remainder
* after the number is divided by 16
*/
rem=quotient%16;
//converting the number into character
if(rem<10)
rem=rem+48;
else
rem=rem+55;
//Populating the characters into the array
hex_num[i]=(char)rem;
i++;
//Calculating the quotient
quotient=quotient/16;
}
//Displaying the hexadecimal number
System.out.print("The Number in Hexadecimal is :");
for(int k=i-1;k>=0;k--)
{
System.out.print(hex_num[k]);
}
}
}
_____________________
output:
Enter a decimal number :51966
The Number in Hexadecimal is :CAFE
