predict the output:

#includestdio.h
int main()
{
    int a=40,b=60,c=70,d=1;
    if(ab&&ac&&ad)
    {
        printf("max is %d",a);
    
    }
    else if(bc&&bd)
    {
         printf("max is %d",b);
    }
    else if(cd)
    {
     printf("max is %d",c);
    }
    else 
    {
         printf("max is %d",d);
    }
    return 0;
