This bootcamp is part of the Programming / CS Bootcamps

Getting started with C programming.

  1. Reading - start reading through one of the following (pick one that seems an easy read for you) before you start working on the programming problems.
    1. The C Book - a bit older, suitable for people with just a bit of programming experience
    2. C Programming Tutorial - suitable for people with no previous programming experience
    3. Fresh2Refresh Tutorial - more of a summary, easy to find particular topics
    4. cplusplus.com - contains references for functions, often one of the first search results on google searches for C
    5. MIT C course - with lecture notes and assignments
    6. Cornell C course - with lecture notes and assignments
  2. Work on solving these problems - https://www.hackerrank.com/domains/c. Start with the first problem and work your way up from there.
  3. Get C installed on your computer - download and install some C compiler/IDE. We use gcc (see https://gcc.gnu.org/install/binaries.html). You could use any compiler/IDE that is C (not C++). Eclipse (see https://www.eclipse.org/downloads/) would be fine. So would MS Visual Studio (see https://visualstudio.microsoft.com/). Or Clang (see http://releases.llvm.org/download.html). Or some in-browser C site, like https://repl.it/languages/c or https://www.onlinegdb.com/online_c_compiler.
  4. If you are a current or incoming ISU student, or an ISU alumni, sign up for the ISU CS Mattermost at https://judy.indstate.edu. Note that you need to use your @sycamores.indstate.edu email address to sign up. Look for the C Programming Channel (direct link is https://judy.indstate.edu/isu-cs/channels/c-programming). When asking about the hackerrank problems make sure to refer to them using the title hackerrank gives them.

That's it for now. Let's see how far you can get with solving the hackerrank problems! Good luck!

List of Problems

Here are problems to work on from the hackerrank set. Note that you should work on more than just this set, but these are ones we are ready to help you solve!

Basic Programming

These problems are all pretty basic - require a single loop, if statement, etc. They are good when you are just getting started with C.

A Bit More Involved

These problems require nested loops, working with arrays, or other things that are the next level of difficulty. Solve all of the Basic Programming problems before starting on these.

When you have finished all of these problems, let us know so we can add more...

And a Bit More

These problems are still a bit more involved. Some require some abstract thinking about the problem, a programming "trick", or other key insight.

After That

If you are able to do all of the problems above, then you don't need us to give you lists of problems any more. You can pick problems to work through on your own. Some suggested places with problems are as follows.

On CS Systems - gcc, g++

For CS courses that use C and C++, the gcc and g++ compilers are normally used. These are already installed on the CS server. If you have a C or C++ program, you compile it by first logging into the CS server using Putty or another terminal program and typing

gcc code.c -o outputName

for C, or g++ for c++. You run the resulting program by typing ./outputName (and then enter/return) at the shell prompt (aka command line). For programs that you are assigned as part of a course, you need to make sure your C/C++ programs compile and run using gcc/g++. Note that programs made using MS Visual Studio or some other compiler will normally not work straight away with gcc/g++ because there are some differences in which functions are included in the header files.
