It is a programmer's responsibility to contribute to society and human well-being is true.
Explanation:
- It is a programmer's responsibility to contribute to society and human well-being is true.
- The Association for Computing Machinery (ACM) is known as the world's largest educational and scientific computing society.
- It has its own Code of Ethics and another set of ethical principles which were also approved by the IEEE as the known standards of teaching and practicing software engineering.
- Programmers contribute to develop computer systems which can reduce negative impression to the society.
- The negativity includes as threats to safety and health, which can be reduced and make everyday activities and work easier.
- software developers should reduce the risk of harming others due to the coding errors or the security issues which could impact human well-being.
Answer:
Let the two string type variables be var1 and var2. The value stored in these two variables is : The "use" of quotations causes difficulties.
- The variable which uses quoted string:
string var1 = "The \"use\" of quotations causes difficulties.";
- The variable which does not use quoted string:
string var2 = "The " + '\u0022' + "use" + '\u0022' + " of quotations causes difficulties.";
- Another way of assigning this value to the variable without using quoted string is to define a constant for the quotation marks:
const string quotation_mark = "\"";
string var2 = "The " + quotation_mark + "use" + quotation_mark + " of quotations causes difficulties.";
Explanation:
In order to print and view the output of the above statements WriteLine() method of the Console class can be used.
Console.WriteLine(var1);
Console.WriteLine(var2);
In the first statement escape sequence \" is used in order to print: The "use" of quotations causes difficulties. This escape sequence is used to insert two quotation marks in the string like that used in the beginning and end of the word use.
In the second statement '\u0022' is used as an alternative to the quoted string which is the Unicode character used for a quotation mark.
In the third statement a constant named quotation_mark is defined for quotation mark and is then used at each side of the use word to display it in double quotations in the output.
