In this c string function article, you will learn how to manipulate strings using C functions along with examples such as puts , gets , strlen , etc. C language is created for developing system-based applications which are used to directly interact with the hardware devices such as kernels, drivers, etc. Basically for all system-related communication as it is a low-level system friendly programming language.

C programming language is considered to be the base of all the programming languages which is also commonly called the procedural programming language, mid-level programming language, and structured programming language. It is specific to a machine i. It is not that easy to understand though as it requires the basic programming knowledge and mindset. String function is easy to use. Here we will discuss how to use string function in C programming with the help of examples. It can also be used to concatenate two strings.

This is the C language based function which is used to display the string on the console screen. This is different from the printf function in the regard that puts writes the string s and a newline to stdout i. This function in the below example means that the string of s is declared with a size of 5 with the character data type.
