operator in CLogical NOT is denoted by exclamatory characters (!), it is used to check the opposite result of any given test condition.If any condition's result is non-zero (true), it returns 0 (false) and if any condition's result is 0(false) it returns 1 (true)....
If in a problem there are multiple operators present, then this type of problem is solved according to this order of operator groups. Logical operator is the member of this operator groups. There are three types of logical operators present in C language. NOT ! ( 1st Priority ) AND && (...
Why to Use: It helps in negating a condition, which is useful when you want to ensure that a certain condition does not hold before proceeding with an action. Example: This program checks if the variable a is zero using the logical NOT (!) operator. Code: #include <stdio.h> int main...
The following C code employs the NOT operator in awhileloop − #include<stdio.h>intmain(){inti=0;while(!(i>5)){printf("i = %d\n",i);i++;}return0;} Output In the above code, thewhileloop continues to iterate till the expression "!(i > 5)" becomes false, which will be wh...
The&operator always evaluates both operands. When the left-hand operand evaluates tofalse, the operation result isfalseregardless of the value of the right-hand operand. However, even then, the right-hand operand is evaluated. In the following example, the right-hand operand of the&operator...
a{The ‖ operator is the logical OR in C.) The If statement in this test would evaluate to TRUE, since any pattern of bits in cust-discnt obeys one of these two conditions. {‖操作员是逻辑或在C.),如果声明在这个测试将评估配齐,因为所有位模式在cust-discnt服从这二个情况之一。[translate]...

Logical OR Operator in the programming language is denoted by the symbol ‘!’. The Logical NOT Operator returns a negate value i.e. if the condition is not satisfied then it will return a True value. If the condition is satisfied, then it returns a False value. ...
