Is there any way to do this?

Francisco Rogelio Abramo (1)
I need a program who ask for a number of persons (n persons)
and asks for each person's age...

then it should remember the number of person and it's ages...
and then print the different range lists of the persons:

Range 1: 0-18 years
Range 2:19-30 years
Range 3:31-60 years
Range 4:61years or more.


for example this needs to be the output:

enter number of persons:6

enter age for person 1: 35
enter age for person 2: 40
enter age for person 3: 14
enter age for person 4: 78
enter age for person 5: 24
enter age for person 6: 12


Range 1 persons (0-18):
person 3: 14 years
person 6: 12 years

Range 2 persons (19-30):
person 5: 24 years

Range 3 persons (31-60):
person 1: 35 years
person 2: 40 years

Range 4 persons (61->):

person 4: 78 years


This is my source code(It's not working)

Is there any easier way to do that, or what's the mistake in my code?
please can some one help me out?

There is a much easier way to do this. I'll post my solution soon.

}

Eh, it could be better.

He didn't want to store their names, did he?
