Chapter 10: Problem 32

Assume that str1 and str2 are string class objects. Write code that displays "They are the same!" if the two objects contain the same string.

Short Answer

Expert verified

Question: Write a code snippet that compares the contents of two string objects (str1 and str2). If they have the same content, display "They are the same!". Answer: To compare the contents of two string objects and display the message if they are the same, you can use the following code snippet: ```cpp #include #include int main() { std::string str1, str2; // assume str1 and str2 are assigned some values str1 = "Hello, world!"; str2 = "Hello, world!"; if (str1 == str2) { std::cout << "They are the same!" << std::endl; } return 0; } ``` In this code snippet, `str1` and `str2` are compared using the equality operator `==`, and if they are the same, the message "They are the same!" is displayed.

Step by step solution

Comparison of Strings

To compare two string objects (str1 and str2) if they contain the same content, we can use the equality operator (==), which returns true if the strings are equal and false if they are not.

Implement an If Statement

With the comparison done using the equality operator, we can now use the 'if' statement syntax to display the message "They are the same!" when the equality operator returns true. That means both the strings contain the same content. Here is the step-by-step solution: ```cpp #include #include int main() { std::string str1, str2; // assume str1 and str2 are assigned some values str1 = "Hello, world!"; str2 = "Hello, world!";

Compare String Values and Display Message

if (str1 == str2) { std::cout << "They are the same!" << std::endl; } return 0; } ``` In this code snippet, we are using the 'if' statement to check if the result of the comparison (str1 == str2) is true. If it is true, then it will print "They are the same!" on the screen. If they are not the same, no output message will be displayed.
