Agree that it also depends on your target platform - Java for Android (with ability for a C/C++ wrapper), Swift and Objective C (and C/C++) for Apple, C# (and C/C++) for Microsoft
So while all major platforms have their preference, you can see they support C and C++ as well so that's not a bad choice to expose yourself to the world.
That being said - There was a study last year: 15 best paying programming languages in 2016 that put Java, Python, R, Objective C, Swift, C#, JavaScript, Perl, C++, SQL, Ruby on Rail, C, in this order of demand in the market - but starting with C and C++ to understand OO programing will get you on the right path
