This is a language question.

#include <stdio.h>
int main(void) {


    char name[22];
    printf ("What's your name?" ");
    scanf_s("%s", name, sizeof(name));

    int age;
    printf ("How old are you?" ");
    scanf_s("%d", &age);

    float weight;
    printf ("How much do you weigh?" ");
    scanf_s("%f", &weight);

    double height;
    printf ("How tall are you?" ");
    scanf_s("%lf", &height);

    char what[22];
    printf ("What crime did you commit?" ");
    scanf_s("%s", what, sizeof(what));

    printf("\n\n--- criminal information ---\n\n";
    printf("name: %s\n", name);
    printf("age: %d\n", age);
    printf ("Weight: %").2f\n", weight);
    printf ("Key: %").2lf\n", height);
    printf("Crime: %s\n", what);


    return 0;
}

scanf_s("%s", name, sizeof(name));

scanf_s("%s", what, sizeof(what));
