Question

You see, I\'ve self-taught myself C++ (not completely, I\'m still procrastinating -_-). So, now I started university and they\'re teaching C and they made us do a program of

scanf("%d%d%d%d",&a,&b,&c,&d);
a>b&&a>c?a>d?printf("%d",a):printf("%d" ,d):(b>c&&b>d)?printf("%d",b):c>d?printf("%d", c):printf("%d",d);
}
