1. It is so important for all application builders to always check data received from unknown sources before using that data. This is because of the Security related reasons and vulnerabilities .For example the data received might contain harmful hidden viruses. Web applications are accessed by internet and these are the most vulnerable to attacks by hacker or intruders using harmful data containing malware. This can cause security breaches due to the security flaws or bugs in Web applications. So to overcome such security risks which can cause damage in the Web applications, data from unknown sources should be checked.

Answer:
#include<ios>// HEADER FILe
#include<iomanip> // HEADER FILE
using namespace std;// namespace
int main() // main function
{
double tem=103.45632; // variable declaration
cout<<" The outside Temperature is:";
cout<<fixed<<setprecision(2)<<tem; // display
return 0;
}
Explanation:
<u>The following are the description of the program</u>.
- set the required header files and namespaces, then declare the main method and inside the main function.
- Set the double data type variable 'tem' and initialize the value '103.45632'.
- Finally, print the following message and print the output through the cout that is predefined function.
Answer:
Explanation:
A disk block works by transferring data between the disk and main memory units which are called the blocks, whose size can range drastically from 512 bytes to several thousand. This data is converted to hardware-level cylinder, surface, and sector number which makes accessing the data immensely slower than accessing data in the main memory. This time constraint is also the main reason as to why accessing a disk block is so expensive.
