我有如下代码:
void Foo(int& a, string& b, vector<int>& c) {
... // 30 lines of code are same as another function
... // 10 lines of code to parse and assign value to vector<int>& c
}
void Foo(int& a, string& b, map<string, int>& d) {
... // 30 lines of code are same as another function
... // 10 lines of code to parse and assign value to map<string, int>& d
}
有什么办法可以避免重复这 30 行代码?在这种情况下我应该使用函数重载吗?
编辑:
如果代码不容易分离出来怎么办?像:
void Foo(int& a, string& b, vector<int>& c) {
for() {
if(m) ... // 30 lines of code are same as another function
else if(n) ... // 30 lines of code are same as another function
else if(o) ... // 30 lines of code are same as another function
else if(p) ... // 10 lines of 'vector<int>& c' code
else if(q) ... // 10 lines of 'vector<int>& c' code
}
}
void Foo(int& a, string& b, map<string, int>& d) {
for() {
if(m) ... // 30 lines of code are same as another function
else if(n) ... // 30 lines of code are same as another function
else if(o) ... // 30 lines of code are same as another function
else if(p) ... // 10 lines of 'map<string, int>& d' code
else if(q) ... // 10 lines of 'map<string, int>& d' code
}
}
