The Age-Related Eye Disease Study (AREDS) - sponsored by the Federal governmentâs National Eye Institute - has found that taking high levels of antioxidants and zinc can reduce the risk of developing advanced age-related macular degeneration (AMD) by about 25 percent.
C++ Overloading (Operator and Function) C++ allows you to specify more than one definition for a function name or an operator in the same scope, which is called function overloading and operator overloading respectively.
You can write any C++ program without the knowledge of operator overloading. But, operator operating are profoundly used by programmer to make a program clearer. For example: you can replace the code like: calculation = add(mult(a,b),div(a,b)); with calculation = a*b+a/b; which is more readable and easy to understand. Operator overloading cannot change the precedence of operators and associativity of operators. 2  But, if you want to change the order of evaluation, parenthesis should be used. 3  Not all operators in C++ language can be overloaded.
