怎样把输出放在一行？
急急急急！！！！
正在线，急急急！
#include<iostream>
using namespace std;
int main()
{
int n; //2<=n<=100;
cin>>n;
for(int i=(n*n+(n-1));i>=(n*(n-1)+1);i-=2)
{cout<<i<<" ";} //去掉换行，加个空格
system("pause");
return 0;
}

c++中如何定义字符型变量
include <iostream> include <cstdlib> using namespace std;int main (){ char a,b;int c,d;cin>>a>>b; \/\/应该是先输入a和b c=a-96;d=b-96; \/\/然后再答处理c和d的值。cout<<c<<'\\n'<<d<<endl;system ("pause");return 0;} 对于C与C++来说是没有字符串型的数据类型的，...
C\/C++\/C#从数组中随机抽取一个数(要源码\/重奖)
本人在Borland C++平台已经成功运行该代码，没问题的。include<iostream> include<iomanip> include<cstdlib> include<ctime> using namespace std;int main(){ int a[10][6]={1,2,3,4,5,6,7,8,9,0,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,...

C++随机数的生成?
你需要先初始化随机数种子 include <iostream> include <cstdlib> include <ctime> using namespace std;int main(){ srand((int)time(0)); \/\/ 产生随机种子 把0换成NULL也行 for (int i = 0; i < 10; i++){ cout << rand()%100<< " ";} return 0;} ...
