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
