Thread: simple char** practice

im just wondering if im using a 'char**' (and dynamic memory) properly, if you could let me know. ie, missing another set of []'s or a * or & somewhere.

Code:

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

int main()
{
    
    char* test= "hello there";
    
    char** temp = (char**) malloc(sizeof(char**) * 1);

    temp[0] = (char*) malloc(sizeof(char*)* 20);
    
    strcpy(temp[0],test);
    printf("'&#37;s'\n",temp[0]);
    
    free(temp[0]);
    free(temp);
    
    getchar();
}

i know this program isnt useful, im just wondering if it is correct.
thanks
