我正在为我的编程类编写这个程序,它有一堆愚蠢的约束,比如我必须使用嵌套if else语句,我必须使用cin.getLine()来获取玩家的名字。它应该抓住每个球员的名字并计算他们的击球率。
这不是整个程序,而是我遇到错误的部分。当我在命令提示符下运行它时,我可以很好地接收名字,但在那之后第二个cin.getline()不会读取任何输入。建议?
#include <iostream>
#include <iomanip>
#include <string>
using namespace std;
int main()
{
char name1[100], name2[100], name3[100];
int numBat, numHit;
double avg1, avg2, avg3;
// Get Average for Player 1
cout << "What's Your Name? ";
cin.getline(name1, 100);
cout << "How many times have you been at bat? ";
cin >> numBat;
if(numBat < 0 || numBat > 25)
{
cout << "ERROR ::: Number of Times at Bat Cannot Be Less Than 0 or Greater Than 25. Run Program Again." << endl;
return 0;
}
else
{
cout << "How many times have you hit the ball? ";
cin >> numHit;
if(numHit < 0)
{
cout << "ERROR ::: Number Hit Cannot Be Less Than 0. Run Program Again." << endl;
return 0;
}
else
{
// Calculate Average for Player 1
avg1 = numHit / numBat;
// Get Average for Player 2
cout << "What's Your Name? ";
cin.getline(name2, 100);
cout << "How many times have you been at bat? ";
cin >> numBat;
cout << "How many times have you hit the ball? ";
cin >> numHit;
}
}
}

我认为这是一个缓冲问题。尝试在第二个cin
之前刷新getline
:
cin.clear(); // clear the buffer
cin.sync();
如果不起作用,请尝试以下方法:
cin.ignore(256, '\n'); // ignore the endline and char(256)

在getline
之后,您需要使用cout << endl;
输出换行符。
答案 2 :(得分:0)
使用时
cin >> numBat;
它没有读取换行符,所以下一个cin.getline()会读取并继续。
使用
cin >> numBat;
cin.ignore(80,'\n');
