C ++用户输入4个数字，程序检查它们哪个更大，小于

Question

我只想快速提示如何做到这一点让我走上正轨。顺便说一句，我是编程新手，所以一些解释会很受欢迎。

所以它基本上是这样的：用户输入由空格分隔的4个数字，程序会在它们之间输入小于的数字。

例如：

input 1:
2 4 6 6
output 1:
2<4<6=6

input 2:
5 5 1 5
output 2:
5=5>1<5

Answer 1

// create variables to store the numbers
int first, second;

// read in the first numbers
cin >> first;
// output the first number
cout << first;

// loop through the numbers as they are inputed
while(cin >> second) {
  // check all the possibilities 
  if(first < second) cout << "<";
  else if(first > second) cout << ">";
  else cout << "=";
  cout << second;
  first = second;
  // go back around again
}
