Pointer assignment vs strcpy in C

main.c

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

char* str;
int num;

void create() {
    num = 100;
    str = malloc(sizeof(char) * num);
}

void process() {
    char example[100] = "This is a test";
    
    // BAD, pointer to example gets copied, example will be deallocated
    // str = example;
    
    // GOOD, example's contents get copied
    strcpy(str, example);
    
    printf("%s\n", str);
}

int main(int argc, char* argv[]) {
    create();
    process();
    printf("String from process(): %s\n", str);
    return 0;
}
