Is there a way to make GCC alert me when I provide a signed integer to function that accepts only unsigned one?
c++, compiler-errors, gcc, unsigned-integer
Solution
Yes, `-Wsign-conversion`
Beware that `-Wconversion` doesn't enable this warning for C++ code, although it does for C code.
Problem
This code gives me no warnings when compiled with `g++`: ``` unsigned int myFunc(unsigned int integer) { return integer; } int main() { int x = -1; std::cout << myFunc(x) << std::endl; } ``` It compiles fine but the result is wrong: `4294967295`. Does GCC have any compiler `-W*` options for that?
