无法使用向量存储数字

Question

vector<int> oper(int A, int B) {
    
    std::vector <int> arrayV;

    int addition = A + B;
        arrayV.push_back(addition);
    int mutiplication = A * B;
        arrayV.push_back(mutiplication);
    int subtraction;
        if(A >=B ){
            subtraction = A - B;   
        }
        else(B >A );{
            subtraction = B - A;
        }
        arrayV.push_back(subtraction);
    int division;
         if(A >=B ){
            division = A / B;   
        }
         else(B >A );{
            division = B / A;
        }
        arrayV.push_back(division);
}

//有谁知道我的代码哪里出了问题，它一直告诉我“纠错错误(SIGSEGV)"，我希望arrayV能够在+，*，-，/之后存储数字；

正如我和其他人在评论中所指出的，您忘了使用return arrayV;。而且，您的else语法错误。

std::vector<int> oper(int A, int B) {
    
    std::vector <int> arrayV;

    int addition = A + B;
    arrayV.push_back(addition);

    int mutiplication = A * B;
    arrayV.push_back(mutiplication);

    int subtraction;
    if(A >=B ){
        subtraction = A - B;   
    }
    else{
        subtraction = B - A;
    }
    arrayV.push_back(subtraction);
    int division;
    if(A >=B ){
        division = A / B;   
    }
    else{
        division = B / A;
    }
    arrayV.push_back(division);
    return arrayV;
}
