Finally, we use the printf() function to print the length of the string.<\/p>\n<p>It is important to note that the strlen() function returns a value of type unsigned int, therefore when using the printf() function to output it, you need to use %u for formatting.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In C language, you can use the strlen() function to determine the length of a string.
