I guess the thread will be soon on hold (“off topic”), so let me show quickly the corrected code:
#include<stdio.h>
int main (void)
{
    char y = 10;
    char* format = "%d";
    __asm
    {
        movzx eax, y
        add eax,1
        push eax
        push format
        call printf
        add esp, 8
    }
    return 0;
}
