c++编程输入四个数，输出最大的数

Posted 2023-03-16

参考技术A #include <istream>
using namespace std;

int main()

int a,b,c,d;
int temp,max;
cout<<"请输入四个整数"<<endl;
cin>>a;
cin>>b;
cin>>c;
cin>>d;
temp=a>b?a:b;
temp=temp>c?temp:c;
max=temp>d?temp:d;

cout<<"最大的数字是："<<max<<endl;

return 0;
参考技术B t;

void main()

int a, b, c ,d;
cin >> a >> b >> c >> d;
if (a < b)
int t = a;
a = b;
b = t;

if (c > a)
else if (c > b)
if (d > a)
else if (d > b)

cout << a << ' ' << b << endl;
参考技术C #include <iostream>
using namespace std;

void main()
int* a;
a = new int[4];
cout << "Please input 4 digits: " << endl;
cin >> a[0] >> a[1] >> a[2] >> a[3];
int *tmp = new int;
*tmp = a[0];
for(int i= 0; i<3;i++)
if(a[i]< a[i+1])
*tmp = a[i+1];


cout << "The maximal number is " << *tmp << endl;
