Sort problem

[tomtom61695]

I am trying to sort an input file with 6 lines, each having a ID number, a first and last name, and a salary. There needs to be three outputs all depending on how its sorted. The first by ID, the second by name, and the last one by salary. Right now I am having problems just sorting the Id and Salaries. The input I am using as a sample is as follows:
ID Name Salary
1000 George Washington 10000
2000 John Adams 15000
1212 Thomas Jefferson 34000
1313 Abraham Lincoln 45000
1515 Jimmy Carter 78000
1717 George Bush 80000

And When I try to sort the ID's and the salaries, It's sorting all of them except for the last one, ID 2000 and Salary 80000. Any help would be much appreciated?

using namespace std; 

struct Employee{
int id;
string first;
string last;
double salary;
};

void get_data(ifstream &inp, Employee data[], int &count);
void sort_id(ifstream &inp, Employee data[], int &count);
void sort_pay(ifstream &inp, Employee data[],int &count);

int main(){
int count = 0;
string input_filename;
Employee data[100];
    
cout << "Enter the name of the file you would like to be sorted: ";
	cin >> input_filename;
	ifstream inp;
	inp.open(input_filename.c_str());
	get_data(inp, data, count);
    sort_id(inp, data, count);
    sort_pay(inp, data, count);
    
    return EXIT_SUCCESS;
}

void get_data(ifstream &inp, Employee data[], int &count){

    for (int i = 0; i < 6; i++){
	inp >> data[count].id;
	inp >> data[count].first;
	inp >> data[count].last;
	inp >> data[count].salary;
        count++;
    }
}


void sort_id(ifstream &inp, Employee data[], int &count){
    int temp = -1;
    for (int i=0; i< count; i++)
    {
        if (data[i].id > data[i+1].id){
            temp = data[i+1].id;
            data[i+1].id = data[i].id;
            data[i].id = temp;
        }
        
    }
    for (int i = 0; i < count; i++){
        cout << data[i].id << endl;
    }
}

void sort_pay(ifstream &inp, Employee data[], int &count){
    int temp = -1;
    for (int i=0; i< count; i++)
    {
        if (data[i].salary > data[i+1].salary){
            temp = data[i+1].salary;
            data[i+1].salary = data[i].salary;
            data[i].salary = temp;
                
        }
    }
    for (int i = 0; i < count; i++){
        cout << data[i].salary << endl;
    }
}
