C++ String Exercises: Check a string is a title cased string or not

Last update on December 20 2024 12:26:01 (UTC/GMT +8 hours)

The string where words start with an uppercase character and the remaining characters are lowercase is called the title cased version of the string

Write a C++ program to check if a given string is a title-cased string or not. When the string is title cased, return "True", otherwise return "False".

Sample Data:
(“The Quick Brown Fox.”) -> "True"
("C++ String exercises") -> "False"
("red, green, white") -> "False"

Sample Solution-1:

C++ Code:

#include <bits/stdc++.h> // Includes all standard libraries

using namespace std; // Using the standard namespace

string test(string text) { // Function to check if the given string is title cased or not
    for (int i = 0; i < text.length(); i++) { // Loop through each character in the string
        if (text[i - 1] == ' ' || i == 0) { // If the current character is the first character or preceded by a space
            if (text[i] < 'A' || text[i] > 'Z') { // If the character is not an uppercase letter
                return "False"; // Return "False" as it's not title cased
            }
        }
    }
    return "True"; // If all characters fit the conditions, return "True" as it's title cased
}

int main() {
    string text = "The Quick Brown Fox."; // Declare and initialize a string
    // string text = "C++ String exercises";
    // string text = "red, green, white";

    cout << "Original String:\n";
    cout << text; // Output the original string
    cout << "\n\nCheck the said string is a title cased string or not!\n";
    cout << test(text) << endl; // Output the result of whether the string is title cased or not
}

Sample Output:

Original String:
The Quick Brown Fox.

Check the said string is a title cased string or not!
True

Sample Solution-2:

C++ Code:

#include <bits/stdc++.h> // Includes all standard libraries

using namespace std; // Using the standard namespace

string test(string text) { // Function to check if the given string is title cased or not
	for (int i = 1; i < text.length(); i++) { // Loop through each character starting from the second character
		if (!isupper(text[i]) && text[i - 1] == ' ') // If the current character is not uppercase and the previous character is a space
			return "False"; // Return "False" as it's not title cased
	}
	return "True"; // If all characters fit the conditions, return "True" as it's title cased
}

int main() {
   //string text = "The Quick Brown Fox.";
   string text = "C++ String exercises"; // Declare and initialize a string
   //string text = "red, green, white";

   cout << "Original String:\n";
   cout << text; // Output the original string
   cout << "\n\nCheck the said string is a title cased string or not!\n";
   cout << test(text) << endl; // Output the result of whether the string is title cased or not
}

Sample Output:

Original String:
C++ String exercises

Check the said string is a title cased string or not!
False
