Answer:
False is the correct answer for the above question.
Explanation:
- In java programming language or any other programming language, any loop can be infinite.
- It is because the infinite loop is called for that loop which is not run in a finite number of times.
- The loop is used to repeat some lines in a finite number of times. Any loop has three things- first is the initial value which tells the loop to start, The second is the condition check which states when the loop will stop and the third is an operation which directs some variable, so that the condition may be false after some finite amount of time.
- If the condition will not false in any iteration of the loop, then the loop can proceed for an infinite amount of time.
- The above-question states that the while loop and do while loop can be infinite which is a true statement.
- But it also states that the 'for' loop can not be infinite which is not a correct statement which is described above. Hence false is the correct answer to the above question.
Answer:
First we understand what is hash function.A hash function is mostly used in Hashmaps. It maps different keys to a set of values.There may occur a case when we have same key but different values.This case is called collision.So we have to use different collision handling techniques that are open addressing and separate chaining.
A perfect hash function maps key-value pair such that there are no collisions.
Answer:
double x = 2.5;
double y = -1.5;
int m = 18;
int n = 4;
string s = "Storm";
string t = "Watch";
The output of the expression "x + n*y - (x+n)*y" is "6.25".
and the output of expression "m/n + m%n" is "6".
Explanation:
for the first expression,
x + n*y - (x+n)*y ,put value of every variables in it.
=2.5+4*(-1.5)-(2.5+4)*(-1.5)
=2.5-6.0-(6.5*(-1.5)
=-3.5+9.75
=6.25
for the second expression,
m/n + m%n, put value of every variables in it.
=18/4 +18%4
=4+2 ("/ will give quotient and % will give remainder")
=6
Answer:
D - Fiber-optic Cables
Explanation:
Electromagnetic interference affects cables made from different metals and can corrupt the data running through them. However, Fiber-optic cables are constructed from glass (non-metallic) and transmit pulses of light as signals to transfer data, this means that the cables are most resistant and not susceptible to EMI.
