解析GMNS（General Modeling Network Specification）数据格式可以使用C++编程语言。下面是一个基本的C++示例代码，用于解析GMNS数据文件：
”`cpp
#include
struct Node {
int id;
double x;
double y;
};
struct Link {
int id;
int fromNodeID;
int toNodeID;
};
std::vector
std::vector<Node> nodes;
std::ifstream file(filename);
if (file.is_open()) {
std::string line;
while (std::getline(file, line)) {
std::istringstream iss(line);
Node node;
if (iss >> node.id >> node.x >> node.y) {
nodes.push_back(node);
}
}
file.close();
}
return nodes;
}
std::vector parseLinks(const std::string& filename) {
std::vector<Link> links;
std::ifstream file(filename);
if (file.is_open()) {
std::string line;
while (std::getline(file, line)) {
std::istringstream iss(line);
Link link;
if (iss >> link.id >> link.fromNodeID >> link.toNodeID) {
links.push_back(link);
}
}
file.close();
}
return links;
}
int main() {
// 解析节点数据
std::vector<Node> nodes = parseNodes("nodes.csv");
// 解析链接数据
