Program to count the number of characters in a word

Write a program to count the number of characters in a word.

Examples:

Input: Word: "programming"
Output: 11

Input: Word: "hello"
Output: 5

Approach: To solve the problem, follow the below idea:

To count the number of characters in a word, maintain a variable to count all the characters. Iterate through each character in the word and increment the counter for every character.

Step-by-step algorithm:

• Initialize a counter variable to 0.
• Iterate through each character in the word.
• For each character encountered, increment the counter.
• After iterating through all characters, the counter will contain the total number of characters in the word.

Below is the implementation of the algorithm:

Number of characters: 11

Time Complexity: O(N), where N is the length of the word.
Auxiliary Space: O(1)
