Given S is a string variable and the function call fflush(stdin) will clear the input buffer. What code in the followings will allow user input a string certainly?Select one:a.fflush(stdin) ; gets(S);b.gets(S)c.puts(S)d.get(S);

Select the correct answerWhen gets () function reads from stdin, which operation gets () performs?OptionsDeletes the ‘\t’Deletes the terminating ‘\n’Puts adds it.Nothing gets() do.

Which of the following C++ statements is used take input from the user?

What is the output of this program if the string bar is supplied as input? #include <iostream> #include <string> using namespace std; int main() { string s1 = "foo"; string s2; getline(cin,s2); cout << s2.append(s1); return( 0 ); } bar foo foobar barfoo

In this challenge, we practice reading input from stdin and printing output to stdout.In C++, you can read a single whitespace-separated token of input using cin, and print output to stdout using cout. For example, let's say we declare the following variables:string s;int n;

In the following code, which of the variables, a, b, c, d and e are strings/pointer-to-strings when code is at /* A */?#include <string.h>#include <stdio.h>void f(char *p) {    p = "hello";}int main() {    char a[16], c[16], *d, e[16];    char b[16] = {'h', 'e', 'l', 'l', 'o'};    strcpy(a, "hello");    f(c);    d = "hello";    scanf("%s", e); // assume that the end-user entered hello\n    /* A */    return 0;}
