Answer 1

I think it's some kind of bug. When you try:
char c = getchar();
cout << c;
cin >> c;
cout << c;
And send two separate inputs, it will work fine, so it may be just SoloLearns bug

Answer 2

A.S. The problem is that you can't input anything in the C++ code. As author mentioned - In C code it works.

Answer 3

Becz you not printing value that's why it showing no output use printf and cout it will work

#include <stdio.h>

int main() {
//getchar();
printf("%c",getchar());
return 0;
}
