the codes posted above is my program what it suppose to do is to make a class seat plan for a person depending on the option he/she chooses



but it seems to be having a problem in this part (the one underlined)....please help me this due on monday and i badly need help


void arrange(studentsrecord studrec[100][100], int arranger,int pupil)
{ studentsrecord *itm;
[u][i]itm = studrec;[/u]
for(int x=0;x<pupil-1;x++)
{
studentsrecord *item = itm+1;
for(int y=x+1;y<pupil;y++)
{
if(arranger==1){
for(int y=0;y<strlen(itm->lname);y++)
if(itm->lname[y] > item->lname[y]){
studentsrecord *i=new studentsrecord;
*i = *itm;
*itm = *item;
*item = *i;
}
}
item++;
}
itm++;
}
}

[vlad from moscow]

studentsrecord *itm;
i]itm = studrec;

The code above is invalid because the left and the right operands of the assignment in the last statement has incompatible types.
