Cpp

CPP is an acronym that can refer to several distinct concepts depending on the context. In computing, CPP most often denotes the C preprocessor, a tool that processes source files for C and C++ before compilation. It handles macro substitution, file inclusion, and conditional compilation via directives such as #define, #include, and #if. In many development environments, cpp is invoked automatically by compilers like GCC or Clang as part of the build process.

In Canada, CPP stands for the Canada Pension Plan, a mandatory social insurance program administered by the government. It provides retirement, disability, and survivor benefits to workers and their families, funded through payroll deductions and governed by federal rules.

In professional payroll practice, CPP refers to the Certified Payroll Professional credential offered by the American Payroll Association. The designation recognizes expertise in payroll processing, payroll tax laws, benefits, and compliance.

In political history, CPP can denote the Communist Party of the Philippines, a Marxist-Leninist organization formed to promote socialist revolution in the Philippines. It has operated with an armed wing in some periods, and its activities have been subject to government restrictions and legal action in the Philippines.

If used in writing, the intended meaning is usually clear from context, and some contexts may require explicit definition to avoid ambiguity.
