Chapter 9: Problem 5

How do you find the length of a string?

Short Answer

Expert verified
Answer: The steps to find the length of a string are: 1. Understand the problem and determine the input: The input is a string, which is a sequence of characters. The goal is to find the number of characters in the string. 2. Plan the approach: Plan to count the characters in the string sequentially. 3. Start counting from the first character: Begin counting from the first character of the string and keep track of the count. 4. Continue counting each character in the string: Count the characters one by one until reaching the end of the string, without skipping any characters. 5. Finish counting and note the final count: The final count represents the length of the string or the number of characters in the input string. 6. Present the result: Present the result as the length of the input string in the desired output format or specific programming language.

Step by step solution

01

Understand the problem and determine the input

First, we need to understand that a string is a sequence of characters. The task is to find the length of this sequence, or in other words, the number of characters present in the string. The input to the problem will be a given string.
02

Plan the approach

Next, plan to count each character in the string sequentially. In programming languages such as Python, the length of a string can be found using built-in functions. For our step-by-step guide, we will use a manual counting approach to demonstrate the process, which can be adapted to any programming language or situation.
03

Start counting from the first character

Begin counting from the first character of the string. Keep track of the count as we progress through the characters in the string.
04

Continue counting each character in the string

Continue counting the characters in the string one by one until reaching the end of the string. Ensure not to skip any characters.
05

Finish counting and note the final count

Once the end of the string has been reached, stop counting. The final count will represent the length of the string, or the number of characters present in the input string.
06

Present the result

Finally, present the result as the length of the input string. The result can be written or presented in various ways, depending on the desired output format or the specific programming language being used.

If a string has 10 characters, what is the index of the last character?

Assume the variable name references a string. Write a for loop that prints each character in the string.

Write a loop that asks the user "Do you want to repeat the program or quit? \((\mathrm{R} / \mathrm{Q})^{\prime \prime} .\) The loop should repeat until the user has entered an \(\mathrm{R}\) or \(\mathrm{Q}\) (either uppercase or lowercase).

Write an if statement that displays "Digit" if the string referenced by the variable ch contains a numeric digit. Otherwise, it should display "No digit."

Assume the variable big references a string. Write a statement that converts the string it references to lowercase, and assigns the converted string to the variable little.
