Can one (re)set all the values of an array in one line (after it has been initialized)?

Question

In C, I know I can make an array like this

int myarray[5] = {a,b,c,d,e};

However, imagine the array was already initialised like

#include
#include

int *setarray(int *ar,char *str)
{
    int offset,n,i=0;
    while (sscanf(str, " %d%n", &n, &offset)==1)
    {
        ar[i]=n;
        str+=offset;
        i+=1;
    }
    return ar;
}

int main()
{
    int *sz=malloc(5*sizeof(int)),i;

    //call
    setarray(sz,"10 30");

    //output
    for(i=0;i<2;i++)
        printf("%d\n",sz[i]);

    return 0;
}
