String Processing

Strings processing

String processing refers to manipulation and analysis of strings. It encompasses various operations such as searching, sorting, concatenation, tokenization, parsing, and pattern matching. It is essential in extracting insights, interpreting human languages, validating and cleaning data, compressing data, encrypting and decrypting data, integrating data, and generating text.

Finding string length

Let’s make a function, str_length():

int str_length(char str[ ]);

In this function, we’ll pass the string as an argument, calculate the length using a loop, and return the length from the function. The loop will terminate when the indexed value is '\0' or 0 or NULL.

Let’s write down a complete code below:
