    malloc in structures

    I was wondering if u could malloc in a structure parts at a t time.

    typedef struct {
        char part[10];
        char part2[20];
        randomstruct * ptr;
    } struct1;
    Is there a way to malloc space for the part and part2 without touching the pointer for randomstuct
    struct1 test;
    test->part = malloc(sizeof(part));

    You would need to declare them as pointers.
    typedef struct {
        char* part;
        char* part2;
        randomstruct * ptr;
    } struct1;
    struct1 test;
    test.part = malloc(10);
    test.part2 = malloc(20);
