    Hope this helps for easy solution and better understanding:

    class Matrix{
    public: 
        vector<vector<int>> a;
        
        Matrix operator +(const Matrix& b){
            int n = a.size();
            int m = a[0].size();
            Matrix result;
            result.a.resize(n, vector<int>(m, 0)); // 2D vector mxn with entries=0
            
            for(int i=0; i<n; i++){
                for (int j=0; j<m; j++){
                    result.a[i][j] = a[i][j] + b.a[i][j];
                }
            }
            return result;
        }     
};

    Operator overloading makes custom types in C easier to use with familiar operators, improving code clarity. Cricbet99 club registration

    class Matrix{ public: vector> a; Matrix(int n = 0, int m = 0) { a.resize(n, vector(m)); } Matrix operator+(Matrix const& obj){

    int n=a.size(); int m=a[0].size(); Matrix res(n,m); for(int i=0;i

    Hello i want to share my solution, enjoy:

    class Matrix {
public:
    vector<vector<int>> a;

    Matrix operator+(const Matrix& b) {
    Matrix m;
    m.a.resize(b.a.size());
        for (int i = 0; i < a.size(); i++) {
            m.a[i].resize(b.a[i].size());
        }

    for (int i = 0; i < b.a.size(); i++) {
        for (int j = 0; j < b.a[i].size(); j++) {
            m.a[i][j] = a[i][j] + b.a[i][j];
        }
    }
    return m;
}
};

    class Matrix {
public:
    vector<vector<int>> a;
    
    Matrix operator+(const Matrix& other) {
        Matrix result;
        int n = a.size();
        int m = a[0].size();
        
        for (int i = 0; i < n; i++) {
            vector<int> row;
            for (int j = 0; j < m; j++) {
                row.push_back(a[i][j] + other.a[i][j]);
            }
            result.a.push_back(row);
        }
        
        return result;
    }
};
