MISRA C++: Rule Example (No Dynamic Memory in Safety-Critical Code) — Misra-c-cpp Code
MISRA C++ discourages dynamic allocation in safety-critical systems. Example shows a compliant static allocation approach.
// Non-compliant: dynamic allocation
int* data = new int[10];
// Compliant: use static or stack allocation
int data[10];Misra-c-cpp Language Guide
MISRA C and MISRA C++ are coding standards developed to facilitate safety, reliability, and maintainability in embedded systems, especially in automotive, aerospace, and critical industries.
Primary Use Cases
- ▸Automotive embedded software development
- ▸Safety-critical avionics code
- ▸Industrial control firmware
- ▸Medical device software
- ▸High-integrity and mission-critical systems
Notable Features
- ▸Rule-based coding guidelines for C/C++
- ▸Focus on safety, reliability, and maintainability
- ▸Supports static analysis enforcement
- ▸Includes both mandatory and advisory rules
- ▸Covers C language and object-oriented C++ constructs
Origin & Creator
Created by the Motor Industry Software Reliability Association (MISRA) in 1998, initially for the automotive industry; later expanded to C++ and broader safety-critical domains.
Industrial Note
Extensively used in automotive ECUs, aerospace flight control software, industrial PLC firmware, and other high-integrity embedded systems.
