C++ 中可以使用 %8d输出空 $8$ 格。

#include<bits/stdc++.h>
using namespace std;
int main()
{
    int a,b,c;
    scanf("%d %d %d",&a,&b,&c);
    printf("%8d %8d %8d",a,b,c);
    return 0;
}

这题可以使用setw()函数。

#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
  int a, b, c;
  cin >> a >> b >> c;
  cout << setw(8) << a << " " << setw(8) << " " << setw(8) << b << " " << setw(8) << c << endl;
  return 0;
}

也可以使用printf()函数。

#include <cstdio>
int main()
{
  int a, b, c;
  scanf("%d %d %d", &a, &b, &c);
  printf("%8d %8d %8d\n", a, b, c);
  return 0;
}

#include<bits/stdc++.h> using namespace std; int main(){ int a,b,c; cin>>a>>b>>c; printf("%8d %8d %8d",a,b,c); return 0; }

哇哦！（‘~’）
