    A way to printf out in printf?

    Hello,

    is there a way to printf out.

    what i want is explode (" ") into 1 line and no spaces.
    i'll explode it with ("_")
    Code:
    int contents = 0;
    const char *setexplodetoname[] = {};
    
    char st[] = "Where there is will there is a way.";
    char *ch;
    ch = strtok(st, " ");
    while (ch != NULL)
    {
        printf("%s\n", ch);
        setexplodetoname[contents] = ch;
        contents++;
        ch = strtok(NULL, " ");
    }
    
    for (int i = 0; i < contents; i++)
    {
        printf("works.......\n");
        printf("%p\n", &setexplodetoname[i]);
    }
    i got this here output:
    Code:
    works.......
    0x7ffe381fa880
    works.......
    0x7ffe381fa888
    works.......
    0x7ffe381fa890
    works.......
    0x7ffe381fa898
    works.......
    0x7ffe381fa8a0
    works.......
    0x7ffe381fa8a8
    works.......
    0x7ffe381fa8b0
    works.......
    0x7ffe381fa8b8
    i except to get the name of explode below works....)

    Do you want us to guess (again) what all the missing things are in your code snippet?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    > const char *setexplodetoname[]
    Well this has ZERO space allocated to it.

    > setexplodetoname[contents] = ch;
    So every time you do this, you're hosing someone else's memory.
