This code first opens the file example.txt in read mode. Then, it uses a while loop to read each file line using fgets(). Until fgets() returns NULL, indicating that the file’s end has been reached, the loop keeps going. Ultimately, the file is closed, and the program exits. Exam...

As we can observe from the above example.scanf()stops scanning as soon as it encounterswhitespaceor newline. This, in fact, makes taking string inputs usingscanf()a bit troublesome. This can be easily avoided by using some other input functions likegets()andfgets(). In this article, we ...

In this case, the contents of str are indeterminate. They may not even be null terminated. Example: How fgets() function works #include <iostream> #include <cstdio> using namespace std; int main() { int count = 10; char str[10]; FILE *fp; fp = fopen("file.txt","w+"); fputs...
