 1.1编程基础之输入输出(10题)

 Hello, World!

#include<iostream>
using namespace std;
int main()
{
cout<<"Hello, World!"<<endl;
	return 0;
}

输出第二个整数 

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

  对齐输出　

#include<iostream>
using namespace std;
int main()
{
	int a,b,c;
	cin>>a>>b>>c;
    printf("%8d %8d %8d",a,b,c);
	return 0;
}

输出保留3位小数的浮点数　

#include<iostream>
using namespace std;
int main()
{
	float a;
	cin>>a;
	printf("%.3f",a);
	return 0;
}

输出保留12位小数的浮点数

#include<iostream>
using namespace std;
int main()
{
	double a;
	cin>>a;
	printf("%.12f",a);
	return 0;
}

 空格分隔输出

#include<iostream>
using namespace std;
int main()
{
	char a;
	float b;
	double c;
	int d;
	cin>>a>>d>>b>>c;
	printf("%c %d %f %f",a,d,b,c);
	return 0;
}

 输出浮点数

#include<iostream>
using namespace std;
int main()
{

	double c;
	cin>>c;
	printf("%f
%.5f
%e
%g
",c,c,c,c);
	return 0;
}

#include<iostream>
using namespace std;
int main()
{
	cout<<"                ********"<<endl;
   	cout<<"               ************"<<endl;
   	cout<<"               ####....#."<<endl;

#include<iostream>
using namespace std;
int main()
{
	char t;
	cin>>t;
	for(int i=0;i<2;++i)
	{
		for(int j=0;j<2-i;++j)cout<<" ";
