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

Answer: To compare the contents of two string objects (e.g., str1 and str2), you can use the '==' operator. If the contents are the same, the '==' operator returns true, and you can use an if statement to display a message. For example: ```cpp #include #include int main() { std::string str1 = "Example string"; std::string str2 = "Example string"; if (str1 == str2) { std::cout << "They are the same!" << std::endl; } return 0; } ``` In this example, the contents of str1 and str2 are the same, so the message "They are the same!" will be displayed.

Step by step solution

Comparing string objects

To compare the contents of string objects, use the '==' operator. This will return true if both strings have the same content and false otherwise. For example: ```cpp if (str1 == str2) { // Strings have the same content } ```

Write an if statement to check if str1 and str2 have the same content

Use an if statement to check if str1 and str2 have the same content. If the condition is met (i.e., the strings are the same), execute the code inside the if statement. The code should be as follows: ```cpp if (str1 == str2) { // Code to execute if the strings are the same } ```

Display the message "They are the same!"

If the condition in the if statement is met (i.e., str1 and str2 have the same content), display the message "They are the same!". The final code should be: ```cpp #include #include int main() { std::string str1 = "Example string"; std::string str2 = "Example string"; if (str1 == str2) { std::cout << "They are the same!" << std::endl; } return 0; } ``` This code will compare the contents of str1 and str2. If they are the same, it will display the message "They are the same!".
