Code style evolution :
// newbie, 11 lines
public string getsex (int num)
{
if (num==0)
{
return "female" ;
}
else
{
return "male" ;
}
}
// 1 year later, 6 lines
public string getsex (int num) {
if (num==0) {
return "female" ;
}
return "male";
}
// 2 years later + lazy writing, 3 lines
public string getsex (int num) {
return num == 0 ? "female " : "male" ;
}
