Function Return Type Mismatch

semantic

warning: return makes integer from pointer without a cast

Description

Returning a value that doesn't match the function's declared return type.

Common Causes

• Returning a pointer from a function declared to return an int
• Returning a float from a function declared to return an int
• Not returning any value from a non-void function

Example of Error

Error Code

int getGreeting() {
    return "Hello, World!";
}

Solution

Change the return value to match the function's return type, or change the function's return type.

Corrected Code

char* getGreeting() {
    return "Hello, World!";
}

Additional Tips

• Make sure the function's return type matches what you intend to return
• Use void for functions that don't return a value
• Be consistent with return types across your codebase
