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...
C++ Logical Operators - Learn about logical operators in C++ including AND, OR, and NOT operators with examples and usage.
Left || Right的結果。 此特製化的範本會完美地轉送結果,其具有operator||所傳回的類型。 備註 針對使用者定義的類型,並沒有任何最少運算的運算元評估。 兩個引數都是由operator||評估。 範例 C++ // functional_logical_or.cpp// compile with: /EHsc#include<deque>#include<algorithm>#include<functional>...
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...
||The logical-OR operator performs an inclusive-OR operation on its operands. The result is 0 if both operands have 0 values. If either operand has a nonzero value, the result is 1. If the first operand of a logical-OR operation has a nonzero value, the second operand isn't evaluated...
这两个参数都通过 operator|| 计算。示例C++ 复制 // functional_logical_or.cpp // compile with: /EHsc #include <deque> #include <algorithm> #include <functional> #include <iostream> int main( ) { using namespace std; deque <bool> d1, d2, d3( 7 ); deque <bool>::iterator iter1,...
