Predict the output:

#includestdio.h
int main()
{
    int a,b,c,d;
    printf("enter the value of a,b,c,d:");
    scanf("%d%d%d%d",&a,&b,&c,&d);
    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;
}

Take input a=68,b=56,c=57,d=34
