Chapter 9: Problem 42

True or False Pointers may be compared using the relational operators.

Short Answer

Expert verified

Answer: True

Step by step solution

Understand pointers

Pointers are variables that store the memory address of another variable. In languages like C and C++, pointers are a powerful tool for working with memory and arrays. Pointers can point to variables of any data type, such as integers, characters, or structures.

Recall relational operators

Relational operators are used to compare two values and return a boolean result (either true or false) based on the comparison. Common relational operators include: - Less than (<) - Greater than (>) - Less than or equal to (<=) - Greater than or equal to (>=) - Equal to (==) - Not equal to (!=)

Pointers and relational operators

When comparing pointers using relational operators, we are comparing the memory addresses stored in the pointers, not the actual values of the variables that they point to. This comparison can be helpful to determine, for example, the position of elements in an array or to implement algorithms that require memory address comparisons. Given this information, we can conclude that the statement is:

Conclusion

True. Pointers may be compared using relational operators, as the comparison is based on their memory addresses, not the values they point to.
