Question

is it possible to do say

int filename = 0;  
typedef struct{  
    char name;  
    char sname;  
    int number;  
}foo;

foo filename;  
filename++;  
foo filename;

and have a new foo struct named 1 and another named 2?

Answer 1

C isn’t interpreted language, so you can’t create variable names runtime. The other way is to create array having multiple instances.

typedef struct{  
char name;  
char sname;  
int number;  
}foo;
foo *files = malloc(sizeof(foo)*3);
files[0].name = "A";
files[1].name = "B";
files[2].name = "C";

Edit: used malloc instad new foo[3]
