Answer:
showProduct(int,double)
for example: showProduct(10,10.5) is the correct answer even showProduct(10,10.0) is also correct but showProduct(10.0,10.5) or showProduct(10,10) or showProduct(10.0,10) are wrong calls.
Explanation:
The code is
- <em>public static void showProduct (int num1, double num2){</em>
- <em> int product;</em>
- <em> product = num1*(int)num2;</em>
- <em> System.out.println("The product is "+product);</em>
- <em> }</em>
showProduct is function which asks for two arguments whenever it is called, first one is integer and second one is of type double which is nothing but decimal point numbers. Generally, in programming languages, 10 is treated as integer but 10.0 is treated as decimal point number, but in real life they are same.
If showProduct( 10,10.0) is called the output will be 'The product is 100'.
Strange fact is that, if you enter showProduct(10,10.5) the output will remain same as 'The product is 100'. This happens because in the 3rd line of code,which is <em>product=num1*(int)num2</em>, (int) is placed before num2 which makes num2 as of type integer, which means whatever the value of num2 two is given, numbers after decimal is erased and only the integer part is used there.
This is necessary in JAVA and many other programming languages as you <u>cannot</u><u> multiply two different datatypes</u> (here one is int and another is double). Either both of them should be of type int or both should be of type double.
Answer:
error: incompatible types
Explanation:
Given
The attached code
Required
The output
Variable "a" is declared as float
While p is declared as a pointer to an integer variable
An error of incompatible types will be returned on line 3, <em>int *p = a;</em>
Because the variables are not the same.
To assign a to p*, we have to use type casting.
Hence, (b) is correct
Answer:
0-9
Explanation:
count 0 as 1
len(0,1,2,3,4,5,6,7,8,9)=10
Answer:
1111000
Explanation:
perform the following. write from right to left:
- is the number even? then write down a 0
- is the number odd? then write down a 1 and subtract 1
- divide by 2
- repeat until you reach 0.
So for 120:
120 is even, so write down a 0 and continue with 120/2=60
60 is even, so write down a 0 and continue with 60/2=30
30 is even, so write down a 0 and continue with 30/2=15
15 is odd, so write down a 1 and continue with 14/2=7
7 is odd, so write down a 1 and continue with 6/2=3
3 is odd, so write down a 1 and continue with 2/2=1
1 is odd, so write down a 1 and finish with 0
