[英]How to store struct data in an array in C++?
I have this program for school it gets data about a student, does a few calculations and stores the data in a struct which is returned by the input function. 我在学校有这个程序,它获取有关学生的数据,进行一些计算并将数据存储在由输入函数返回的结构中。
Right now I've only got it working for one student, but I need to be able to store and output data for more than one student. 现在我只为一个学生工作,但是我需要能够存储和输出一个以上学生的数据。
"Right now I've only got it working for one student, but I need to be able to store and output data for multiple students." “现在我只为一个学生工作,但是我需要能够存储和输出多个学生的数据。”
Use std::vector
使用std::vector
int n; //No. of student
std::vector<studentType> vec;
studentType s;
for(size_t i =0; i<n ;++i)
{
s = input();
vec.push_back(s);
}
And then you can access 然后您可以访问
vec[i].studentID ; // etc, for ith student
On another note, void main
is not legal C++, use int main
另外, void main
不是合法的C ++,请使用int main
