 # Data sharing (OpenMP)
-A local variable in a C function lives on the stack and is private to that call. When multiple threads run the same code, each gets its own stack, so locals are naturally separate. Variables declared *outside* a parallel region are different: all threads share the same memory location.
+A local variable in a C function lives on the stack and is private to that call. When multiple threads run the same code, each gets its own stack, so locals are naturally separate. Variables declared *outside* a parallel region are different: all threads share the same memory location. **Data sharing** in OpenMP makes this explicit. Every variable accessed inside a parallel region is either **shared** (all threads read and write the same location) or **private** (each thread gets its own copy). The default for variables declared outside the region is `shared`, which silently causes a race condition if threads write to them:
