How can you combine logical AND and OR operators in C?

• Use AND for & and OR for |

• Use && for AND and || for OR

• Use AND for && and OR for ||

• Use & for AND and | for OR

What is the order of precedence for operators in C?

• Logical AND || > Logical OR &&

• Multiplication / > Division *

• Parentheses () > Postfix increment and decrement ++ -- > Prefix increment and decrement ++ -- > Unary plus and minus + - > Logical NOT ! > Bitwise NOT ~ > Multiplication * > Division / > Modulus % > Addition + > Subtraction - > Left shift << > Right shift >> > Less than < > Less than or equal to <= > Greater than > > Greater than or equal to >= > Equal to == > Not equal to != > Bitwise AND & > Bitwise XOR ^ > Bitwise OR | > Logical AND && > Logical OR || > Conditional ?: > Assignment = += -= *= /= %= &= ^= |= <<= >>= > Comma ,

• Bitwise OR & > Bitwise XOR ^

Give an example of using a relational operator in C.

• if (x == y) { // do something }

• while (x != y) { // do something }

• switch (x < y) { // do something }

• for (x > y) { // do something }

Explain the difference between logical AND and logical OR operators.

• Logical AND requires both conditions to be false

• The main difference between logical AND and logical OR operators is that AND requires both conditions to be true, while OR requires at least one condition to be true.

• Logical OR requires both conditions to be true

• Logical AND requires at least one condition to be true

How does the logical NOT operator work in C?

• The logical NOT operator in C is denoted by the dollar sign ($).

• The logical NOT operator in C is written as the letter N.

• The logical NOT operator in C is represented by the exclamation mark (!).

• The logical NOT operator in C is represented by the asterisk symbol (*).

Write a C code snippet that demonstrates the use of logical operators.

• int a = 5, b = 10; if (a > 0 && b < 20) { printf("Both conditions are true"); }

• int a = 5, b = 10; if (a > 0 || b > 20) { printf("At least one condition is true"); }

• int a = 5, b = 10; if (a > 0 & b < 20) { printf("Both conditions are true"); }

• int a = 5, b = 10; if (a > 0 || b < 20) { printf("At least one condition is true"); }
