RobotC is an interpreted C-like programming language available for the VEX PIC and VEX Cortex. It offers real-time debugging and a relatively simple set of internal libraries mostly based on the use of (real or virtual) arrays.
Features
Built-in debugger allows pausing and resuming user code and real-time monitoring of variables
IDE integrates firmware updates, code authoring, compilation, and flashing into one program
Primitive multi-tasking built in
Support available on website and from VEX
Simple and easy to learn, no need for users to interest themselves with technical details
Shortcomings
Interpreter emulates an 8-bit processor, substantially slowing user code and preventing any numerically intensive algorithms from being useful
Library abstracts many details and prevents advanced access or fine-tuning VEX sensors​
Neither free nor open-source, and only works on Windows
Lack of support for objects, dynamic allocation, wide integers, or interrupts severely limits code capabilities
Array-like syntax can be confusing and is rife with opportunities for indexes out of bounds or overflow
Optimizer is poor and IDE is generally low-quality, with a fixed code style and terrible code completion
