[ad_1] Here are two differences: An overloaded assignment operator must be a member of the class being assigned to; it cannot be declared as a free function. Copy and move assignment operators will be implicitly declared for your class if you do not declare them yourself (subject to certain restrictions). [ad_2] solved What is the … Read more

It is different from other operators in that it can be overloaded, meaning that it can be given a new meaning or behavior.

On the other hand, there is no === operator in python, that’s why your program fails in that case. Contrary … Read more
[ad_1] Hmmm Some task… Do one thing create a pointer of that class in your cpp file and assign memory to it using heap allocation. class *myfield = (class*)malloc(no_of_instances*sizeof(class)) Now use that object which is there in your header file assign myfield’s address to that object(hope that is pointer) Now it should work fine.. try … Read more
[ad_1] As you can see here, the | operator has a higher precedence than the assignment operator =. Therefore, when you don’t wrap (a = false) in parentheses : if (a = false | (b = false) || (c = true) | (d = true)) is equivalent to if (a = (false | (b = … Read more
[ad_1] a1=a2 //What does this line mean??? = is the assignment operator. This actually assigns the value of the LHS operand to the RHS operand. Here, this line means, assign the value of a2 to a1, i.e, this assigns the a2 pointer to a1. That is, a1 and a2 points to the same memory location. … Read more
