関数からベクトルを返そうとしていますが、いくつか問題があるようです....
現在、これは私が持っている最高のものです：
int* OptimizedSkillLevels(int skillLevel, const int numSkills, int duration, FragmentOptimizationParameters FOP){
//some code to work with some things was here
vector<int> skills(numSkills);
int skillIncrement = 0;
while (skillLevel > FOP.levelDifference){
skills[skillIncrement%numSkills] += FOP.levelDifference;
skillLevel-= FOP.levelDifference;
skillIncrement++;
}
skills[skills.size()-1] += skillLevel;
//at this point, the vector skills is full of the correct values, which is what really matters.
}
int* skillsArr = &skills[0];
return skillsArr;
}
この関数呼び出しからアクセスすると、ガベージ値が表示されるようですが:
cout << OptimizedSkillLevels(skillLevels[i], userMaxNumSkills, durations[i], FOPs[FOPindex])[j] << ", ";
具体的には-17891602、何であれ、毎回そこから得てい[j]ます。
そこで、次のようにベクトルに変換しようとしました。
vector<int> OptimizedSkillLevels(int skillLevel, const int numSkills, int duration, FragmentOptimizationParameters FOP){
//some code to work with some things was here
vector<int> skills(numSkills);
int skillIncrement = 0;
while (skillLevel > FOP.levelDifference){
skills[skillIncrement%numSkills] += FOP.levelDifference;
skillLevel-= FOP.levelDifference;
skillIncrement++;
}
skills[skills.size()-1] += skillLevel;
//at this point, the vector skills is full of the correct values, which is what really matters.
}
return skills;
}
関数プロトタイプを使用:
vector<int> OptimizedSkillLevels(int skillLevel, int numSkills, int duration, FragmentOptimizationParameters FOP);
しかし、これを含む多数のエラーが発生しています(プロトタイプの行で):
1>c:\users\vasu\documents\visual studio 11\projects\composing calc\composing calc\composing calc.cpp(59): error C2143: syntax error : missing ';' before '<'
1>c:\users\vasu\documents\visual studio 11\projects\composing calc\composing calc\composing calc.cpp(59): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
そして、これらは、関数の戻り値の型をベクトルに変更する前に表示されたものはありません...だから、何が起こっているのか本当にわかりません。
