One characteristic of programming languages that varies wide

One characteristic of programming languages that varies widely from language to language is how parameters are passed. Among ALGOL, Pascal, Ada, C, C++, Java, and C#, no two languages pass parameters in exactly the same way. Among these languages, choose the one that you believe has adopted the best approach to parameter passing. Defend your decision by outlining the advantages of the approach of the language that you chose and the disadvantages of the approaches taken by other languages.

Solution

Ans : According to me, the best approach in case of parameter passing is Ada. The languages like C and C++ are not safe because of the use of pointers i.e. passing pointer by value. Java is safe and adopt passing by value but flexibility is an issue in case of java i.e. it is less flexible in case of java. In Algol, approach which is used is passing by name which according to me is not the best approach. Ada defined parameter semantics in, in/out and out and therefore have the most reliability. So, according to me Ada is the best approch of all in case of parameter passing.
