where can we get c/c++ version？

[i4b2c]

Open terminal and write

For C++ version

g++ --version

For C version

gcc --version

For the C++ standard, you can use,

#include <bits/stdc++.h>
using namespace std;
int main()
{
cout<<__cplusplus<<"\n'
return 0;
}

C++11: cplusplus is 201103L. C++14: cplusplus is 201402L. C++17: cplusplus is 201703L. C++20: cplusplus is 202002L.

And for C, you can use,

#include <stdio.h>
int main()
{
printf(__STDC_VERSION__);
return 0;
}

It will return for example 201112L for C11 version
