如何在C++中访问结构中的向量?
问题描述:
我试图访问我的载体,我在一个结构初始化,但是当它编译,显示此错误:如何在C++中访问结构中的向量?
mediaselec.cc: In function 'void leeVector_conjunto(ConjuntoEstudiantes&)': mediaselec.cc:23:4: error: 'ConjuntoEstudiantes' has no member named 'asignaturas' v.asignaturas(num_asignaturas);
#include <vector>
#include <iostream>
using namespace std;
struct Info{
int id_student; //id of a student
vector<double> marks; //Contains all the marks of one student
};
//typedef vector<int> Subconjuntos;
typedef vector<Info> StudentGroup;
/*Read a vector of n student group*/
void enter_group(StudentGroup& v, Subconjuntos& s) {
//Size of the StudentGroup
int n;
cin >> n;
v = StudentGroup (n);
//Num. marks of one student
int num_marks;
cin >> num_marks;
//Ignore this part.
/*
//Numero de subconjuntos
int s_subconjuntos;
cin >> s_subconjuntos;
s = Subconjuntos (s_subconjuntos);
for (int i = 0; i < n; ++i) {
cin >> s[i];
}
*/
//Read all the students with all the marks and store it in v.
for (int i = 0; i < n; ++i) {
cin >> v[i].id_student;
for (int j = 0; j < num_marks; ++j) {
cin >> v[i].marks[j];
}
}
}
int main() {
StudentGroup v;
//Subconjuntos s;
enter_group(v,s);
}
编译器是对的,'ConjuntoEstudiantes'没有名为'asignaturas'的成员。结构信息确实。 – sergej
你想完成什么?我不明白这段代码应该做什么。 – sergej
嗨sergej,我尽我所能,翻译我的简单代码。那么现在我只想在一个向量中存储一组学生,每个人都有num_marks。问题是,我不知道我是否正在访问结构中的矢量。 – BigHelmet
