Dec 5, 2024 · C language provides a built-in function strlen () but in this article, we will learn how to find and print the length of the string using pointers in C. The easiest method to find the length of a string using pointers is by calculating difference between the pointers to the first and last character of the string. Let’s take a look at an example:

Discover how to find the length of a string in C programming using pointers efficiently. This article provides a step-by-step guide and complete code example, empowering programmers to enhance their understanding of string manipulation and pointer usage in C.

First, we will declare a character string as int main() {char a [100]; into length; Then , we will display a message to the user asking him to enter a string as printf ("Enter a string to calculate its length\n"); gets (a); Then we will use strlen function to find the length of …
