ข้อ 1

แพมทำ แต่ไม่ถูกทุกกรณี

include

include

using namespace std;

int ids[] = {99,12,48,105,10,15,25,46,499,128,87,52,221,300,714,188,189,910,412,555}; char genders[] = {'m','f','m','m','f','f','f','m','m','f','m','f','f','m','f','f','f','m','m','f'}; string faculty[] = {"eng","med","econ","med","eng","law","law","dent","med","camt","med","dent","econ","eng","med","eng","eng","econ","econ","agri"}; int N = sizeof(ids)/sizeof(ids[0]);

int main(){ cout << "Input gender and faculty to search:\n"; char gen; string fac; int count = 0; cin >> gen >> fac;

for(int i = 0; i < N; i++){
    if(gen == genders[i] && fac == faculty[i]){
        cout << "Student " << count+1 << ": " << ids[i] << endl;
        count++;
    }
    else if(count < 1){
        cout << "not found" << endl;
        break;
    }
}

return 0;

}

ข้อ 2

จงเขียน Function ชื่อ sort3ints ให้สอดคล้องกับตัวอย่างการใช้งานด้านล่างนี้ ซึ่งจากตัวอย่างการใช้งานจะเห็นได้ว่า sort3ints() จะมีการรับ Input 3 ตัว และไม่มีการ Return ค่าใด ๆ โดยเมื่อเรียกใช้งาน sort3ints() กับตัวแปร a, b, c ตามในตัวอย่าง จะเห็นได้ว่า ค่าที่ถูกเก็บไว้ในตัวแปรทั้ง 3 จะถูกสลับใหม่ โดยที่ค่าที่มากที่สุดจะมาอยู่ที่ตัวแปร a ค่าตรงกลางจะมาอยู่ที่ตัวแปร b และค่าที่น้อยที่สุดจะมาอยู่ที่ตัวแปร c
