Type Conversion Skill

Fixes compilation errors related to incompatible type assignments or conversions.

Detection Patterns

• cannot convert 'X' to 'Y'
• invalid conversion from 'X' to 'Y'
• no viable conversion
• incompatible types

Strategy

1. Identify Types: Extract source and target types from error.
2. Determine Conversion: Choose appropriate cast or method.
3. Apply Fix: Add cast or conversion call.

Instructions

Step 1: Parse the Error

Extract:

• Source type (what you have)
• Target type (what is expected)
• Location of the conversion

Step 2: Common Conversions

From	To	Fix
std::string	const char*	.c_str()
const char*	std::string	Constructor or assignment
int	enum	static_cast<EnumType>(val)
void*	T*	static_cast<T*>(ptr)
Base*	Derived*	dynamic_cast<Derived*>(base)
int64_t	int	static_cast<int>(val) (with care)

Step 3: Apply Fix

Example: string to const char*

// Before (error)
void log(const char* msg);
std::string message = "Hello";
log(message);  // ERROR

// After
log(message.c_str());

Example: enum cast

// Before
int value = 5;
MyEnum e = value;  // ERROR

// After
MyEnum e = static_cast<MyEnum>(value);

Step 4: Verify

Ensure semantic correctness, not just compilation success.
