Answer:
Hydrogen.
Explanation:
Hydrogen is the simplest element that exists. The symbol for the chemical element Hydrogen is "H" and it is a colourless, tasteless, odorless, and highly flammable gas.
Hydrogen is a chemical element found in group (1) of the periodic table and as such it has one (1) electrons in its outermost shell. Therefore, Hydrogen has an atomic number of one (1) and a single valence electrons because it has only one proton and one electron in its nucleus.
Additionally, all stars are made up of Hydrogen.
A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force. Stars are typically made up of two (2) main hot gas, which are Hydrogen (H) and Helium (He).
Answer:
in the body part of the declaration or definition
Explanation:
In functional programming the scope of a variable is in the body part of the declaration or definition. Meaning that as soon as it is declared, whatever body it is in can call and use that variable but not any code outside of that body. For example, in the below code variable (var1) is declared inside func1 and therefore can be used by any code inside the body of func1 but not by code inside func2 since it is outside the body of func1.
void func1() {
int var1;
}
void func2() {
var1 = 2 // This will not work, since var1 is only available in func1()
}
Answer:
White box testing strategy
Explanation:
Pen or penetration testing, also known as ethical hacking is a technique used by an organisation to examine the computer systems, networks and web applications for security vulnerabilities such as loopholes, that can be exploited by an attacker.
There several strategies in pen testing that can be used to check for network vulnerabilities, they are, internal testing, external testing, black box testing, white box testing, blind testing etc.
Unlike in black box testing, white box testing provides all necessary information like IP addresses, network structure, operating system etc, to the pen tester.
