If i may offer a few suggestions; * Given your current family obligations, Take any job you get in any field you are offered. Putting Food on the table and taking care of your Family are the primary non-negotiable needs. * You wanting to work in C/C++ are wants which you pursue on the side to develop expertise in and then make a switch to when you get the right opportunity. This thread already has a lot of actionable good suggestions for you. * Since you already are a "Mobile/Web App" person, go down the Software Stack in the same domain to scratch your C/C++ itch and become an "Expert". As an example for Android go through Roger Ye's books; 1) Embedded Programming with Android: Bringing Up an Android System from Scratch and 2) Android System Programming: Porting, customizing, and debugging Android HAL.
