The C gets function is used to scan or read a line of text from a standard input (stdin) device and store it in the String variable. When it reads the newline character, then the C gets function will terminate.
How to read the string data from console using gets in C Programming, and the differences between the scanf and gets with example. The basic syntax behind the Gets in C Programming language is as shown below.
char *gets(char *str)
or we can simply write it as:
gets(<variable name>)
Gets in C Programming Example
The gets function used to read the complete set of characters from the console. This program will help you to understand this gets function practically.
TIP: You have to include the #include<stdio.h> header before using this Gets function.
// C gets function example #include <stdio.h> int main() { char name[50]; printf("\n Please Enter your Full Name: \n"); gets(name); printf("=============\n"); printf("%s", name); return 0; }

The first printf statement will ask the user to enter any name or string, and the user-specified string assigned to the character array name[50].
printf("\n Please Enter your Full Name: \n"); gets(name);
Next, we used the C programming printf statements to print the output.
printf("%s", name);
Difference between scanf and gets in C Programming
This program will help you to understand the differences between the scanf statement and the gets function in c programming. And why we generally prefer gets over scanf, while we are working with string data.
// C gets function & scanf difference example #include <stdio.h> int main() { char name[50]; printf("\n Please Enter your Full Name: \n"); scanf("%s", name); //gets(name); printf("\n=============\n"); printf("%s", name); return 0; }

From the above screenshot, you can observe that thought we entered Learn C Programming as the text, we are getting the output as Learn. Because, scanf function will consider learning as one value, c as another, and programming as third value. The following screenshot will prove you the same

Let me comment on the scanf(“%s”, name); statement and use gets function to read text from the console.
// C gets function & scanf difference example #include <stdio.h> int main() { char name[50]; printf("\n Please Enter your Full Name: \n"); //scanf("%s", name); gets(name); printf("\n=============\n"); printf("%s", name); return 0; }

From the above screenshot, you can observe that we are getting the complete text without any missing letters.
