Sửa lỗi và viết lại chương trình sau đúng cú pháp (nếu có) #include <bits/stdc++h> Using namespace std ; main () { Int A,B,X; Cout <<"Nhap A ="; Cin>>A; Cout <<"Nhap B="; cin >>B If (A<=B) X=A , ELSE X=B ; Cout<<X } b, Kết quả thu được là gì khi A=20, B=10

2 câu trả lời

chương trình sau khi sửa lỗi:

#include <bits/stdc++h>

using namespace std ;

int main () {

int A,B,X;

cout <<"Nhap A =";

cin>>A;

cout <<"Nhap B=";

cin >>B;

if (A<=B){

X=A;

}else{

X=B;

cout<<X;

}

khi A = 20, B =10 thì vì A > B => X = B

=> X = 10

a. Sửa lỗi và viết lại chương trình

#include <bits/stdc++.h>
using namespace std;
int main()
{
    int A,B,X;
    cout << "Nhap A=";
    cin >> A;
    cout << "Nhap B=";
    cin >> B;
    if (A<=B) X=A; else X=B;
    cout << X;
}

b. Kết quả khi A=20, B=10:

Đáp án: 10

Giải thích: khi A=20 và B=10 thì A>B nên điều kiện sai (if (A<=B)) nên else được thực hiện nên X=B=10
