Found use of deprecated C++ headers CXX-W2030

The use of deprecated C++ headers such as signal.h and assert.h is considered an antipattern, as they are not part of the C++ standard library anymore and have been replaced by their C++ equivalents.

This means that they may not be supported by future versions of C++.

Here's a list of such headers,

• assert.h
• complex.h
• ctype.h
• errno.h
• float.h
• limits.h
• locale.h
• math.h
• setjmp.h
• signal.h
• stdarg.h
• stddef.h
• stdio.h
• stdlib.h
• string.h
• time.h
• wchar.h
• wctype.h
• fenv.h
• stdint.h
• inttypes.h
• tgmath.h
• uchar.h

Consider using their non .h and c prefixed variants, such as cmath for math.h.

Bad practice

#include <iostream>
#include <assert.h>

int main() {
    int x = 5;
    int y = 6;
    assert(x == y);
    return 0;
}

Recommended

#include <iostream>
#include <cassert>

int main() {
    int x = 5;
    int y = 6;
    assert(x == y);
    return 0;
}
