I'm not sure what exactly you are asking because your question is too general.

But for a start, if you haven't done this already.... You probably need to declare a struct where you store your values

Code:
typedef struct{

int age;
int job;
int salary;
int religion;
bool isInASyndicate;

}individual;
Put the struct into use in storing your data:

Code:
individual individuals[100];
Possibly zero initialize all your structs then populate possibly from user input etc

So, what exactly are you having a problem doing? Where have you got?
