c get char * str size via strlen() function and convert char *str to char array

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

int main()
{
    charPointerToCharArray();
    return 0;
}

void charPointerToCharArray()
{
    char *str="Reflection,meditation,practice!";
    int size=strlen(str);
    printf("str=%s,size=%u\n",str,size);
    char chArr[size];
    for(int i=0;i<size;i++)
    {
        chArr[i]=str[i];
    }
    
    for(int i=0;i<size;i++)
    {
        printf("%c\t",chArr[i]);
    }
    printf("\nchArr=%s\n",chArr);
}

void charPointer1()
{
    char *msg="Hello C!";
    int size=sizeof(msg);
    for(int i=0;i<size;i++)
    {
        printf("%c\n",msg[i]);
    } 
    char chArr[size]; 
    for(int i=0;i<size;i++)
    {
        chArr[i]=msg[i];
    }
    printf("Arr=%s\n",chArr);
}
