Error C2106 Left Operand Must Be L Value C
and Interop Question 0 Sign in to vote Hi All, Here expression must be a modifiable lvalue is my code. class Bucket { public: Bucket() {count=0; label=-1; }; public: float label, count; void displayData(); float getLabel(); }; const int visual studio 2016 MAX=2000; Bucket ang[MAX]; ifstream inlabel("Labels of Buckets.txt"); k=0;float labelset;while(inlabel >> labelset && k<1023){ ang[k].getLabel() = labelset; cout << ang[k].getLabel() << endl; k++;} inlabel.close(); float Bucket::getLabel() { return label; } Why it shows"error C2106: '=' : left operand must be l-value"?? I don't really understand
Strcpy
what it means, sicne my label is defined as a float already. Thanks a lot! Thank you for replying! I love this forum!

So a better option would be to have separate member functions for getting and setting label:class Bucket { public: Bucket() : label_(-1.0f), count_(0.0f) { } float getLabel() const { return label_; } void setLabel(float l) { label_ = l; } private: float label_; float count_; }; This is common enough that it is normal to elide the 'get' and 'set' part of the names, and distinguish between the methods only by their parameters and return types:class Bucket { public: Bucket() : label_(-1.0f), count_(0.0f) { } float label() const { return label_; } void label(float l) { label_ = l; } private: float label_; float count_; }; Marked as answer by Yan-Fei W
