Convert character strings in small letters

Writing functions:

strtolower(x)

Converts all of the characters in a string to small letters.

The function that converts string characters into small letters is a reliable tool for processing text data. Each character of the string passed as an argument to the function will be converted to the corresponding small character.

To implement this function, you need to go through each character of the input string and check its type. If the symbol is a capital letter, then it must be converted to a small letter using the appropriate letter code conversion algorithm. For example, you can use an ASCII or Unicode character code table.

The use of this feature can be useful in many areas. For example, in text editors, this can be useful in cases where the user enters text in uppercase and needs to bring it to lowercase for further processing. This function can also be used in data processing applications where textual information must be reduced to lowercase for comparison or analysis.

This code allows you to efficiently convert string characters into small letters and be universal for various programming languages. The conversion operation is performed in linear time, which ensures high performance of this function.

y=strtolower(x);

In this example, the strtolower function receives the input string x and goes through each character of this string, checking its type. If the character is a large letter, then it is converted to a small one, and added to the final string y. If the symbol is not a letter or is already a small letter, then it remains unchanged.

Thus, the function performs the required conversion of string characters into small letters, providing a reliable and versatile tool for processing text data.
