fgets remove newline

To remove the newline character from a string obtained using fgets() in C, you can follow these steps:

  1. Determine the length of the string using the strlen() function from the string.h header. Note that strlen() does not count the terminating null character (\0). Here's an example: c size_t sl = strlen(NAME);

  2. Check if the string is empty (i.e., it begins with or only includes one null character \0). If the length is 0, skip the newline replacement process. Here's an example: c if (sl == 0) { // Skip the newline replacement process. }

  3. Check if the last character of the string is a newline character \n. If it is, replace it with a null character \0. Note that array indices start at 0, so you need to access NAME[sl - 1]. Here's an example: c if (NAME[sl - 1] == '\n') { NAME[sl - 1] = '\0'; }

You can combine steps 2 and 3 into a single step by checking if the length is greater than 0 and the last character is a newline character. Here's an example:

if (sl > 0 && NAME[sl - 1] == '\n') {
    NAME[sl - 1] = '\0';
}

These steps will remove the newline character from the string obtained using fgets() in C.
