Problem w/ FP

Functional programing makes simple things nearly imposible to do . for example I found this exercise on reddit

"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)
for extra credit, have the program log this information in a file to be accessed later."

At first I dismissed it as stupidly trivial but then thought, is there even a way to do this in scheme? And I couldnt think of one. This just shows that scheme sucks for programs used by users. There is no sequential steps to actually accomplish anything

#include <stdio.h>
int main(void) {
    char *name, *username;
    unsigned age;
    printf("What is your name?\n");
    scanf("%m[^\n]", &name);
    printf("What is your age?\n");
    scanf("%u%*c", &age);
    printf("What is your username?\n");
    scanf("%m[^\n]", &username);
    printf("Your name is %s, you are %u years old and your username is %s.", name, age, username);
    free(name);
    free(username);
}
