Inoverload resolution against user-defined operators, the following built-in function signatures participate in overload resolution: booloperator!(bool) booloperator&&(bool,bool) booloperator||(bool,bool) Example Run this code #include <iostream>#include <sstream>#include <string>intmain(){intn=2...
Logical Operators As withcomparison operators, you can also test fortrue(1) orfalse(0) values withlogical operators. Logical operators are used to determine the logic between variables or values: OperatorNameDescriptionExampleTry it &&Logical andReturns true if both statements are truex < 5 && x...
