double转为string (int\float等类似)
#include <string>
#inlcude <sstream>
int main(){
double d=123.456;
string str;
stringstream ss;
ss<<d;
ss>>str;
#inlcude <sstream>
int main(){
double d=123.456;
string str;
stringstream ss;
ss<<d;
ss>>str;
}
string转为double(int\float等类似)
#include <string>
#inlcude <sstream>
int main(){
double s;
string str="123.56";
stringstream ss;
ss<<str;//从str输入
ss>>s;//输出到double
#inlcude <sstream>
int main(){
double s;
string str="123.56";
stringstream ss;
ss<<str;//从str输入
ss>>s;//输出到double
ss.clear();
}
}
挂一漏万，C++暂时够用，以后有需要再补充
、lambda()、filter()、reduce()、推导类表、切片...)
