Compiler Warning (level 3, off) C4242
'identifier': conversion from 'type1' to 'type2', possible loss of data
The types are different. Type conversion may result in loss of data. The compiler makes the type conversion.
This warning is off by default. For more information, see Compiler Warnings That Are Off by Default.
For more information on C4242, see Common Compiler Errors.
The following sample generates C4242:
// C4242.cpp
// compile with: /W4
#pragma warning(4:4242)
int func() {
return 0;
}
int main() {
char a;
a = func(); // C4242, return type and variable type do not match
}
