Hi All,

Scenario starts ......,
1.I have x (dollar) amount, I have been allowed to give constant value say 8(dollar) to each of kid to spend.
2. I have to find out to how many kid I can distribute this amount say (x/8)
For this I found out that If this division is not whole number then roundin up the value
3. Now I get the number of Kids can receive the amount portion say "numKids"
4. Now the another problem : How much can a kid get so I decided to distribute like this :
Total amount : x
Total Kids : numKids
So each kid wil get x/numKids)dollar only when this results in "Whole Number"
If "Division of amount" is not whole number then I have set the rule that The youngest kid get an additional 1 dollar. and all other remaining kids will get the equal part.

Scenario completes...

Are you familiar with the "modulo" function? It tells you the remainder of an integer division. To see it in action, write a program that calculates "x % numKids".
