In this article, I will explain to you, how to read the character array or string from the given file using fgets in C programming with example. Note: You have to include the stdio.h ( header file) before using fgets in C Programming. Syntax of fgets: char *fgets(char * restrict s, int n,FILE * restrict stream); Where,Aug 05, 2017 · Alas, the fgets() function also retains the newline character at the end of input, which is often not what you want. So further processing is necessary when you must peel off the trailing newline. A solution I offered in a blog post from 2013 uses fgets() in an input() function that strips away the newline. Here is that function:
Sep 26, 2019 · fgets(3) is a utility that can read certain number of characters from a stream. You would have realized by now that stdin is also a stream. So, you can let fgets use it. fgets() function in C. The standard C library also provides us with yet another function, the fgets() function. The function reads a text line or a string from the specified file or console. And then stores it to the respective string variable. Similar to the gets() function, fgets also terminates reading whenever it encounters a newline character Note: When the O_NONBLOCK flag is set for the file descriptor’s underlying stream and the thread would be delayed in the fgets() operation, then fgets() will set errno to EAGAIN. In the case of a FIFO stream, if some data has been read into the string buffer, fgets() will return a pointer to the string buffer to indicate the partial read.
fgets is a function in the C programming language that reads a limited number of characters from a given file stream source into an array of characters. fgets stands for file get string. It is included in the C standard library header file stdio.h. The prototype of the function is as follows:
Fgets(), I understand, has the advantage to prevent buffer overflow as a result of the buffer size inclusion in its arguments. However, if I enter a string of >99 chars in the above program, the first 99 chars are displayed in one string, and then the remaining chars which I entered are returned in a following string.

The fgets() function in Line 8 reads in text. The text goes into the name array, which is set to a maximum of ten characters in Line 5. The number 10 specifies that fgets() reads in only nine characters, one less than the number specified. Finally, stdin is specified as the "file" from which input is read. stdin is standard input.
