Convert a decimal to hex and use the hex value to set output pins high

I am taking an integer like 32, converting it to a hex number, and concatenating it with 0X to produce a char output = 0X1F. I then use "output" to set output pins on MSP30 high.
The below code does what I just explained. When I run this, I get the following error: a value of type "char *" cannot be assigned to an entity of type "unsigned char". I don't understand how to fix this. Can someone help please.

char h[17] = "0123456789ABCDEF";
    static uint8_t num = 32; //decimal number to be converted to hex
    char hex[32];
    static uint8_t Quo; // Quotient
    static uint8_t Rem; //Remainder
    char *string = "0X";
    char *output;
    hex[0] = '\0';
    while (num !=0)
    Quo = num/16;
    Rem = num % 16;
    memmove (&hex[1], hex, strlen(hex)+1);
    hex[0] = h[Rem];
    num = Quo;
    output= malloc(strlen(string)+strlen(hex)+1);
    strcpy(output, string );
    strcat(output, hex);
    P1OUT = output ;
