If the test expression is evaluated to false, statements inside the body ofifare not executed. Working of if Statement To learn more about when test expression is evaluated to true (non-zero value) and false (0), checkrelationalandlogical operators. Example 1: if statement // Program to di...

Keep conditions simple: Complex conditions can often be broken down into multiple statements or simplified using logical operators. Use comments wisely: Commenting on the purpose of an If statement can clarify the intention behind complex conditions. ...
In C programming, logical operators are used to perform logical operations, typically to combine two or more conditions. These operators are widely used in control structures like if, while, and for statements. The main logical operators in C are: Logical AND (&&), Logical OR (||) and Logi...
In the above code, thewhileloop continues to iterate till the expression "!(i > 5)" becomes false, which will be when the value of "i" becomes more than 5. i = 0 i = 1 i = 2 i = 3 i = 4 i = 5 C has bitwise counterparts of the logical operators such as bitwise AND (...
3. There can be any number of else..if statement in a if else..if block. 4. If none of the conditions are met then the statements in else block gets executed. 5. Just like relational operators, we can also use logical operators such as AND (&&), OR(||) and NOT(!)....
Here the given expression of logical operator is: 1 y= x < 4 || x < 10 ; Here || operator combined these two conditions. In OR operator statement, if both statements are False, then only the overall result = False. If any statement is “True”, then the overall result is “True...

C is a relatively "low level" language. This characterization is not pejorative; it simply means that C deals with the same sort of objects that most computers do, namely characters, numbers, and address. These may be combined and moved about with the arithmetic and logical operators implemente...
“An expression is a sequence of operators and operands that specifies computation of a value”,这句明确给出了表达式的定义,即表达式是由一系列运算符(operators)和操作数(operands)组成的序列。这既是表达式的定义,同时也指明了表达式的组成成分。运算符指明了要进行何种运算和操作,而操作数则是运算符操作...
