我的学生班的实例帮助!! [英] instances of my student class help!!
问题描述
你好，新发帖，在c ++中遇到了困境。我似乎无法创建我的学生班级的新
实例。我的想法是创建一个数据库，其中用户输入姓氏和图书馆卡号等。
代码我无法编译的是：
...... void main（）{
for（int i = 0; i< 10; i ++）{
学生[i];
cout<< 输入学生姓氏： << endl;
cin>> c;
s [i] .setSurname（c）;
}
}

Hello, new to posting, got a dilema in c++. I cant seem to create new
instances of my student class. The idea is to make a database where
the user inputs surnames and library card numbers etc. The piece of
code I cant get to compile is:
......void main() {
for (int i=0; i<10; i++) {
student s[i];
cout << "Enter student surname: " << endl;
cin >> c;
s[i].setSurname(c);
}
}
Thats the bases!! If anyone can help me pls email direct

int main（）
main（）应该总是返回int，其他任何东西都可能导致未指定
结果。
for（int i = 0; i< 10; i ++）{
student s [i];

.....void main() {

main() should always return int, anything else might cause unspecified
results.
for (int i=0; i<10; i++) {
student s[i];
你到底想要做什么？也许你想要
之类的东西（假设学生是班级名字）：
std :: vector< student>学生们; //你需要#include< vector>
for（unsigned int i = 0; i< 10; i ++）
{
学生; //如果需要，添加构造函数参数。
students.push_back（s）
}
s [0] .setSurname（" ;无论是什么"）;
What exactly are you trying to do here? Perhaps you would like to have
something like (assuming student is the class name):
std::vector<student> students; // You need #include <vector>
for( unsigned int i = 0; i < 10; i++ )
{
student s; // Add contructor parameters if needed.
students.push_back( s )
}
s[0].setSurname( "whatever" );

反转那些：

for（int i = 0; i< ; 10; ++ i）{
cout<< 输入学生姓氏： << endl;
cin>> c;
s [i] .setSurname（c）;
}
}

Reverse those:

cout << "Enter student surname: " << endl;
cin >> c;
s[i].setSurname(c);

Thanx的帮助!!我似乎在c ++上毫无用处，即使我需要这样做也不需要它来支付它！
我的下一个问题是我无法响应用户输入来创建一定数量的
学生实例：
我有：
cout<< 你想加几个学生？在
100"下输入一个数字。 << endl;
cin>> f;
学生[f];
for（int i = 0; i< f; i ++）{
无法编译！ :(
非常感谢任何帮助。
" Howard"< al ***** @ hotmail .com>在消息新闻中写道：< bthqs5>> ..... void main（）{
Thanx for the help!! I seem to be useless at c++ even tho I need to do
it!
My next problem is I cant respond to user input to create an amount of
student instances:
I have:
cout << "How many students would you like to add? Enter a number under
100" << endl;
cin >> f;
student student[f];
for (int i=0; i<f; i++) {
Can''t seem to compile! :(
Would appreciate any help pls.
