Starting point for learning programming

I am a sophomore student from Xi'an University of Posts and Telecommunications, is my major network engineering;
although previously learned C language, but their own school is not very solid, and relatively one-sided, but now decide to learn and deeper to learn to enrich their skills, certainly will not care about the technology and more pressure body;
give yourself some tasks, regular meals to fulfill the program;
I am going to weekend days to give yourself two hours a day to program, if it is idle words also can go to programming, weeks, then I will have enough time to complete the program; the future for the company to go, I did not think well, I believe I will have a clear goal when to.
