Answer is C: Hazard Communication
Hazard Communication Hazard (HCS 2012) provides a coherent and standardized approach to communicating the hazards of chemicals by way of Safety Data Sheets (SDSs) and labels on containers. However, Occupational Safety and Health Administration (OSHA) revised its HCS 2012. In it, they revised criteria for classification of chemical hazards, labeling provisions, hazard statements, and precautionary statements. In addition, modifications were made to health standards substances to ensure requirements for labels and SDSs are consistent with the HCS 2012. According to OSHA’S standards, SDSs should periodically be reviewed and updated.
Answer:
Highest
Explanation:
A interrupt request / IRQ is in which instructions are sent to Cpu and uses an interrupt handler to run distinct program . Hardware interrupts are used to manage occurrences such as obtaining modem or network card information, important presses, or mouse motions.
- Interrupt request 0. – it is a system timer (can not be altered)
- Interrupt request 1 – keyboard controller (can not be changed)
- Interrupt request 2 – cascaded IRQ 8–15 signals (any device configured to use IRQ 2 will genuinely use IRQ 9)
- Interrupt request 3 – serial port 2 controller
- Interrupt request 4 – serial port 1 controller
- Interrupt request 5 –parallel port 2 and 3
- Interrupt request 6 - floppy disk controller
- Interrupt request 7 –parallel port 1. If a printer is not present, it is used for printers or for any parallel port. It can also possibly be shared with a secondary sound card with cautious port management.
As interrupt number increases priority level decreases, Priority level 0 is the highest priority level .
Answer:
- \' is used to escape a single quote in a string enclosed in single quotes like;
my_string = 'this is John\'s ball'.
- \n is used to jump to a new line, Eg;
my_string = "Johns is a good boy\nbut he hates going to school."
the next set of the string after the '\n' character is displayed on the next line.
- \t is used to add a tab space to a string.
my_string = 'Jane is \thungry'
the character adds four character spaces before the word 'hungry'.
- \r adds a carriage return (or enter in keyboards) to start a new block paragraph in a string.
my_string = "Johns is a good boy\rbut he hates going to school."
Explanation:
Escape sequences in programming are used to format strings or output syntax of a program. They always begin with the backslash. Examples of escape sequence are " \' ", "\n", "\t", "\r", etc.
Answer:
C++ code is given below
Explanation:
#include <iostream>
#include <cctype>
#include <string.h>
#include <cstring>
#include <sstream>
using namespace std;
struct Car {
public:
char reportingMark[5];
int carNumber;
string kind;
bool loaded;
string destination;
};
void input(Car *);
void output(Car *);
int main() {
Car *T = new Car;
input(T);
output(T);
delete T;
return 0;
}
void input(Car *T)
{
string str, s;
cout << " Enter the reporting mark as a 5 or less character uppercase string: ";
cin >> str;
for (int i = 0; i < str.length(); i++)
T->reportingMark[i] = toupper(str[i]);
cout << " Enter the car number: ";
cin >> T->carNumber;
cout << " Enter the kind: ";
cin >> T->kind;
cout << " Enter the loaded status as true or false: ";
cin >> s;
istringstream(s) >> boolalpha >> T->loaded;
if (T->loaded == true) {
cout << " Enter the destination: ";
cin.ignore();
getline(cin, T->destination);
}
else
T->destination = "NONE";
}
void output(Car *T)
{
cout << " Reporting Mark: " << T->reportingMark;
cout << " Car Number: " << T->carNumber;
cout << " Kind: " << T->kind;
cout << " Loaded Status: " << boolalpha << T->loaded;
cout << " Destination: " << T->destination << " ";
}
