In C programming, the fflush(stdin) function is used to clear the input buffer memory of any data that may still be stored. It does this by freeing up any memory associated with the standard input stream, known as stdin, which is the default input used for reading any data from command...
What is fflush in C? What is the instruction cycle? What do the following loops print? a. int s = 1; for (int n = 1; n <= 5; n++) { s = s + n; System.out.print(s + " "); } b. int s = 1 What is the difference between i++ and ++i when incrementing a variable...

way of doing this is to callfflush(stdin), despite the fact that this is a misguided application of the standardfflushfunction, an application that is not guaranteed to (and in fact most certainly does not) work everywhere. But it “works” under a large number of popular PC C compilers,...
fflush(stdin); getch(); } void add() { int a, b, sum; cout<<"Enter two numbers:"; cin>>a>>b; sum=a+b; cout<<endl; cout<<"Sum of two numbers is: "<<sum<<endl; } Now if you see in the preceding code, I have optimized it by putting that addition lo...
I was about to mention that you could add a std::string member variable to solve the problem of the temporary in operator const char*(), when I saw you had done so yourself! So I think this removes any "danger." But I agree that c_str() is a more explicit (e.g. greppable) ...
In fact, this addition has been long overdue. PHP is one of the few major programming languages that still didn’t implementfsync() and fdatasync()— that is,until PHP 8.1. Thefsync()function is similar to PHP’s existingfflush()function, but it differs significantly in one way. Whereasff...
fflush (stdin); printf ("Roll : "); scanf ("%d", &s.roll); printf ("Std : "); scanf ("%d", &s.std); if (fwrite(&s, sizeof(s), 1, fp)) { printf ("Record added."); } fclose(fp); } return 0; } Output == Student Database Add records == Name :...
What's new and what changed in 1.7.28 popen now supports the Glibc 'e' flag to set the FD_CLOEXEC flag on the pipe in a thread-safe way. New netinet/ip6.h header. Switch to BSD FILE stream fopen/exit semantics, as in all BSD variants and Linux/GLibc: Don't fflush/lseek a FIL...
