A range of position dependent colors
Answer: The following code is in c++
#include <iostream>
#include<math.h>
using namespace std;
int main()
{
float a,b,c;
cout<<"Enter height and base of triangle\n";
cin>>a>>b; //reading two sides from user
c=sqrt(pow(a,2)+pow(b,2)); //calculating hypotenuse
cout<<"Length of hypotenuse is "<<c; //printing third side of triangle
return 0;
}
OUTPUT :
Enter height and base of triangle
3
4
Length of hypotenuse is 5
Explanation:
In the above code, three variables a, b and c of int type are declared. After that, it is asked from user to enter the value of a and b. The user puts the value and then c is calculated with the help of Pythagoras theorem formulae which squares the values of two sides and then adds them to calculate hypotenuse of a right angled triangle and finally c is printed to console.
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.
Answer:
d. This statement results in input failure.
Explanation:
We are taking input of 3 variables only and those are x,ch,and y. cin is a C++ keyword used take input entered by the user onto the screen cin is not a variable.
The input should of type int char int as written in the code. First is x and character variable ch and then the integer variable y and there should be only three inputs.
