Thread: Please Help!!! Project Due soon!!

how do i pass a pointer to the first set of data kinda like...

void sort(struct data *p);

and what does it look like when i pass it....

main()
{
sort(????)
}

my structure looks like this......





struct student{
int stdnum;
char stdname[40];
bool active;
};
struct classes{
int stdnum;
int classnum;
};
struct subject{
int classnum;
char classname[40];
int topic;
};

//----------------------------------fill in some test data

student data[] = {
{1,"Hall Tim",1},
{2,"Harren Chris",1},
{3,"Lyons Steve",1},
{4,"Lakis Mike",1},
{5,"Doe John",1},
{6,"MacMeyer Tim",1},
{7,"Pulli Jon",1}};

classes course[] = {
{1,101},
{2,101},
{1,102},
{3,102}};

subject sub[] = {
{101,"science",111},
{102,"history",222}};



thanks

here's the code.... and here's the error....

void sort(student data[], int size);



main()
{
int x;

x=sizeof(data)/48;
sort(data,x);


}

i'm sorry for all the questions, i'm just a beginner and i really appreciate your help. My newest problem is that my strcmp() function doesn't seem to be working right....? the code never enters the if() statement...


void sort(student array1[],struct student *p, int size)
{
cout << "Entered Sort Function"<< endl;
int flag=1;
struct student tmp;

while(flag){
flag =0;
if(strcmp(p->stdname,(p+1)->stdname)>0){
cout << "got here" << endl;
tmp = *p;
*(p) = *(p+1);
*(p+1) = tmp;
flag = 1;
}

}

for(int i=0;i<size;i++){
cout << array1[i].stdname << endl;
}
}


and obviously the data doesn't change

thanks, i really appreciate the help, you are saving me!
