Thread: group struct info

Hello All,

I have some data into an struct and I would like to group those information. My struct looks like this:

Code:

struct MyStruct data[MAX];

struct MyStruct {
        char date[20];
        char code[5];
};

void PrintStruct() {
        int x;
        for(x=0; x<MAX; x++) {
                printf("\t\t** data[%d].date: [%s] **\n",x,data[x].date);
                printf("\t\t** data[%d].cc_code: [%s] **\n",x,data[x].code);
        }
}

I would like to count how many records of an certain code I have and group them. For example:

[1]=10
[-1]=99
[8]=12

And so on. Any help ?

Another thing that I'm trying to do is count how many records my stryct has. I've define MAX to 100000 but I don't want to loop all the 10000 records if I only have 20 records on that moment, for example.

Any help ?

Thanks a lot,

Could any one give me an example, even if a simple one.

Thanks,
