C/C++ :: Print Out User Input

Create a program that will ask the users name, age, and reddit username. have it tell them the information back, in the format: your name is (blank), you are (blank) years old, and your username is (blank).

So I started making my program

#include <stdio.h>
int main(int argc, char* argv[]) {
char name;
int age;
char username;
printf("Please input your name,your age,and reddit username
");
scanf(" %c %d %c", &name, &age, &username);
printf(" %c %d %c", name, age, username);
return 0;
}

My program outputted H 0 and an upside down question mark. I was thinking that maybe the error in the program was that i was supposed to use %s instead of %c but im not entirely too sure.
