Answer:
a. quantum computing and telecommunications
Explanation:
Both quantum computing and telecommunications need materials with specific optical, electrical, and magnetic properties to advance, and nanotechnologies open the opportunity for nanomaterial with incredible properties. From antennas with special magnetic properties to faster optical fiber from more stable material to store qubits to super thermal insulators, nanotechnologies will change the way we build and design telecommunication systems, and it will allow us to build stable and reliable quantum computers.
B. Loosening the drain plug with a screwdriver
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.
