The swapThree () function swaps three integers a, b, c to b, c, a. Immediately after calling this function, variable a has the value of variable b, b has the value of c, and c has the value of a.
You need to write swapThree () so that main () runs through tests.

Input Description
1 22 3
Output Description
22 3

void swapThree(int &a, int &b, int &c0)//
int t = a;//
a = b;//
b = t;//
int d = b;//
b = c;//
b = d;//
}

thoi toi fix duoc roi
phai la

void swapThree(int &a, int &b, int &c){
int t = a;
a = b;
b = t;
int d = b;

bai struct 4

struct Student{
string name;
double math, physics, chemistry;
Student(string _name){
name = _name;
}
void setMarks(double a, double b, double c){
math = a;
physics = b;
chemistry = c;

}
string getName(){
return name;
}
double getAverage(){
return (math + physics + chemistry) / 3;
}
};
