Using Visual C++ 2019

Seems like Visual C++ 2019 has special codes that are not supported by the standard C++ command structures. For example, many tutorials on-line suggest that one can get input from a console by entering the command as follows:

Libraries #include <cstdio>
#include <iostream>
#include <string>
using namespace std;
char Indata;

.
.
.
getline(cin,Indata);

Produces a compiler error, says cannot find getline!

Additionally, are there any books that would explain the commands and arguments available for the Visual C++ 2019 system?

Your help will be appreciated, Thanks, Sid Kraft

    Hi,

    There are two different getline() function:

    In the <iostream>, we could try to use the following code: 

    char Indata[256];  
std::cin.getline (Indata, sizeof (Indata));

    In the <string>, we could try to use the following code: 

    std::string Indata;  
getline (std::cin, Indata);

    For more details I suggest you could refer to the link: https://stackoverflow.com/questions/4872361/why-are-there-two-different-getline-functions-if-indeed-there-are

    Best Regards,

    Jeanine
