This really depends on the language that you are: most comfortable with and/or most interested in learning. On a personal level I was mostly taught C for my major, so that is what i prefer (you might like java or python instead). The three main books I used in college to learn C were,

Absolute Beginner's Guide to C by Greg Perry

The Joy of C by Lawrence Miller & Alexander Quilici

Absolute C++ by Walter Savitch

Youtube/Google also helped me immeasurably. I hope this helps.
