Operator 逻辑NOT( )运算符 1)逻辑AND()运算符 (1) Logical AND () Operator) Logical AND operator represented by the symbols , it works with two operands and returns 1 if both operands are true (non-zero); 0, otherwise. 逻辑AND运算符由符号“ ”表示它与两个操作数一起使用如果两个操作数均为true(非零)则返回1否则返回1。 0否则。 Note: Operands can be values, conditions, expressions, etc. 注意 操作数可以是值条件表达式等。 Syntax: 句法 operand1 operand2
Truth table: 真相表 operand1operand2operand1 operand2Non-zeroNon-zero1Non-zero000Non-zero0000 操作数1 操作数2 操作数1 操作数2 非零 非零 1个 非零 0 0 0 非零 0 0 0 0 C program to demonstrate the example of logical AND () operator C 程序演示逻辑AND()运算符的示例 #include iostream
using namespace std;
int main()
{
int a 10;
int b 20;
// printing the values
cout a : a endl;
cout b : b endl;
cout endl;
// Logical AND operations
cout (a b) : (a b) endl;
cout (a 0) : (a 0) endl;
cout (0 b) : (0 b) endl;
cout (0 0) : (0 0) endl;
cout endl;
cout (a 10 b 30) : (a 10 b 30) endl;
cout (a 10 b 20) : (a 10 b 20) endl;
cout (a 10 b 30) : (a 10 b 30) endl;
cout (a 10 b 20) : (a 10 b 20) endl;
return 0;
}
Output: 输出 a : 10
b : 20
(a b) : 1
(a 0) : 0
(0 b) : 0
(0 0) : 0
(a 10 b 30) : 1
(a 10 b 20) : 1
(a 10 b 30) : 0
(a 10 b 20) : 0
2)逻辑或(||)运算符 (2) Logical OR (||) Operator) Logical OR operator represented with the symbols ||, it works with two operands and returns 1 if one (or both) operands are true (non-zero); 0, otherwise. 用符号“ || ”表示的逻辑“或”运算符 可用于两个操作数如果一个(或两个)操作数为真(非零)则返回1否则返回1。 0否则。 Syntax: 句法 operand1 || operand2
Truth table: 真相表 operand1operand2operand1 operand2Non-zeroNon-zero1Non-zero010Non-zero1000 操作数1 操作数2 操作数1 操作数2 非零 非零 1个 非零 0 1个 0 非零 1个 0 0 0 C program to demonstrate the example of logical OR (||) operator C 程序演示逻辑OR(||)运算符的示例 #include iostream
using namespace std;
int main()
{
int a 10;
int b 20;
// printing the values
cout a : a endl;
cout b : b endl;
cout endl;
// Logical OR operations
cout (a || b) : (a || b) endl;
cout (a || 0) : (a || 0) endl;
cout (0 || b) : (0 || b) endl;
cout (0 || 0) : (0 || 0) endl;
cout endl;
cout (a 10 || b 30) : (a 10 || b 30) endl;
cout (a 10 || b 20) : (a 10 || b 20) endl;
cout (a 10 || b 30) : (a 10 || b 30) endl;
cout (a 10 || b 20) : (a 10 || b 20) endl;
return 0;
}
Output: 输出 a : 10
b : 20
(a || b) : 1
(a || 0) : 1
(0 || b) : 1
(0 || 0) : 0
(a 10 || b 30) : 1
(a 10 || b 20) : 1
(a 10 || b 30) : 1
(a 10 || b 20) : 0
3)逻辑非()运算符 (3) Logical NOT (!) Operator) Logical NOT operator represented by the symbols !, it works with one operand and returns 1 if the operand is zero;0, otherwise. 逻辑NOT运算符以符号“ ”表示它与一个操作数一起使用如果操作数为零则返回1否则返回0。 Syntax: 句法 !operand
Truth table: 真相表 operand!operandNon-zero001 操作数 operand 非零 0 0 1个 C program to demonstrate the example of logical NOT (!) operator C 程序演示逻辑NOT()运算符的示例 #include iostream
using namespace std;
int main()
{
int a 10;
int b 0;
// printing the values
cout a : a endl;
cout b : b endl;
cout endl;
cout !a : !a endl;
cout !b : !b endl;
cout endl;
// Logical NOT operations
cout !(a || b) : !(a || b) endl;
cout !(a || 0) : !(a || 0) endl;
cout !(0 || b) : !(0 || b) endl;
cout !(0 || 0) : !(0 || 0) endl;
cout endl;
cout !(a 10 || b 30) : !(a 10 || b 30) endl;
cout !(a 10 || b 20) : !(a 10 || b 20) endl;
cout !(a 10 || b 30) : !(a 10 || b 30) endl;
cout !(a 10 || b 20) : !(a 10 || b 20) endl;
return 0;
}
Output: 输出 a : 10
b : 0
!a : 0
!b : 1
!(a || b) : 0
!(a || 0) : 0
!(0 || b) : 1
!(0 || 0) : 1
!(a 10 || b 30) : 0
!(a 10 || b 20) : 0
!(a 10 || b 30) : 0
!(a 10 || b 20) : 0
