Question

I JUST NEED HELP WITH DISPLAY PART!

please help!

thanks in advance

here is your sorting function + display function add this to your project : ---------->>>>>>>>>>>

void sort(int n){
int i,j;
struct student temp;
if(n == 1){
  for(i = 0;i<count;i++){
   for(j = i;j<count;j++){
    if(strcmp(list[i].name,list[j].name) > 0){
     strcpy(temp.name,list[i].name);
     strcpy(temp.class_standing,list[i].class_standing);
     temp.roll_number = list[i].roll_number;
     temp.genderValue = list[i].genderValue;
     temp.tuition_fee = list[i].tuition_fee;
     strcpy(list[i].name,list[j].name);
     strcpy(list[i].class_standing,list[j].class_standing);
     list[i].roll_number = list[j].roll_number;
     list[i].genderValue = list[j].genderValue;
     list[i].tuition_fee = list[j].tuition_fee;
     strcpy(list[j].name,temp.name);
     strcpy(list[j].class_standing,temp.class_standing);
     list[j].roll_number = temp.roll_number;
     list[j].genderValue = temp.genderValue;
     list[j].tuition_fee = temp.tuition_fee;
    }
   }
  }
}else if(n == 2){
  for(i = 0;i<count;i++){
   for(j = i;j<count;j++){
    if(list[i].roll_number > list[j].roll_number){
     strcpy(temp.name,list[i].name);
     strcpy(temp.class_standing,list[i].class_standing);
     temp.roll_number = list[i].roll_number;
     temp.genderValue = list[i].genderValue;
     temp.tuition_fee = list[i].tuition_fee;
     strcpy(list[i].name,list[j].name);
     strcpy(list[i].class_standing,list[j].class_standing);
     list[i].roll_number = list[j].roll_number;
     list[i].genderValue = list[j].genderValue;
     list[i].tuition_fee = list[j].tuition_fee;
     strcpy(list[j].name,temp.name);
     strcpy(list[j].class_standing,temp.class_standing);
     list[j].roll_number = temp.roll_number;
     list[j].genderValue = temp.genderValue;
     list[j].tuition_fee = temp.tuition_fee;
    }
   }
  }
}
}

void display(){
char ch = 's';
while(1){
  printf("\nPlease enter sorting method N(by name ) or R(by roll number)");
  scanf("%c",&ch);
  if(ch == 'n' || ch == 'N'){
   sort(1);
   break;
  }
  if(ch == 'r' || ch == 'R'){
   sort(2);
   break;
  }
  printf("\nthis sorting method is not defined ");
}

printf("\nThere are %d Students in the List ",count);
int i;
for(i = 0;i<count;i++){
  printf("\nName = %s \n",list[i].name);
  if(list[i].genderValue == male){
   printf("Gender = Male\n");
  }else{
   printf("Gender = Female\n");
  }
  printf("Class Standing = %s\nRoll Number = %d\nTuition Fee = %0.2f\n\n",list[i].class_standing,list[i].roll_number,list[i].tuition_fee);
}
