How to check the word cat for the letter i? - briefly
To determine if the word "cat" contains the letter "i", one must examine each character within the word. The word "cat" does not include the letter "i".
To perform this check programmatically, you can use various methods depending on the programming language. Here are a few examples:
-
Python: You can use the
inkeyword to check for the presence of a character.word = "cat" letter = "i" if letter in word: print("The letter is in the word.") else: print("The letter is not in the word.") -
JavaScript: You can use the
includesmethod to check for the presence of a character.let word = "cat"; let letter = "i"; if (word.includes(letter)) { console.log("The letter is in the word."); } else { console.log("The letter is not in the word."); } -
Java: You can use the
containsmethod from theStringclass to check for the presence of a character.String word = "cat"; String letter = "i"; if (word.contains(letter)) { System.out.println("The letter is in the word."); } else { System.out.println("The letter is not in the word."); }
These methods provide a straightforward way to verify the presence of a specific character within a given word.
How to check the word cat for the letter i? - in detail
To determine whether the word "cat" contains the letter "i," one must follow a systematic approach. This process involves examining each character in the word to see if it matches the specified letter. Here is a detailed method to achieve this:
First, identify the word and the letter to be checked. In this case, the word is "cat" and the letter is "i." The word "cat" consists of three characters: 'c,' 'a,' and 't.' The letter "i" is not present in this sequence.
To verify this programmatically, one can use various programming languages. Below are examples in Python and JavaScript, which are commonly used for such tasks.
In Python, the process can be accomplished using a simple loop or the in keyword. Here is an example using a loop:
word = "cat"
letter = "i"
for char in word:
if char == letter:
print(f"The letter '{letter}' is in the word '{word}'.")
break
else:
print(f"The letter '{letter}' is not in the word '{word}'.")In this code, the for loop iterates through each character in the word "cat." If the character matches the letter "i," it prints a message indicating the presence of the letter. If the loop completes without finding the letter, the else block executes, indicating that the letter is not in the word.
Alternatively, the in keyword can be used for a more concise solution:
word = "cat"
letter = "i"
if letter in word:
print(f"The letter '{letter}' is in the word '{word}'.")
else:
print(f"The letter '{letter}' is not in the word '{word}'.")This approach directly checks if the letter "i" is in the word "cat" and prints the appropriate message.
In JavaScript, a similar process can be followed using a loop or the includes method. Here is an example using a loop:
let word = "cat";
let letter = "i";
for (let i = 0; i < word.length; i++) {
if (word[i] === letter) {
console.log(`The letter '${letter}' is in the word '${word}'.`);
break;
}
}
if (i === word.length) {
console.log(`The letter '${letter}' is not in the word '${word}'.`);
}In this code, the for loop iterates through each character in the word "cat." If the character matches the letter "i," it prints a message indicating the presence of the letter. If the loop completes without finding the letter, the condition if (i === word.length) executes, indicating that the letter is not in the word.
Alternatively, the includes method can be used for a more concise solution:
let word = "cat";
let letter = "i";
if (word.includes(letter)) {
console.log(`The letter '${letter}' is in the word '${word}'.`);
} else {
console.log(`The letter '${letter}' is not in the word '${word}'.`);
}This approach directly checks if the letter "i" is in the word "cat" and prints the appropriate message.
In summary, checking the word "cat" for the letter "i" involves examining each character in the word to see if it matches the specified letter. This can be done manually or programmatically using various methods in different programming languages. The examples provided in Python and JavaScript demonstrate how to implement this check efficiently.
