You will include code that will validate all user input. If the user inputs an invalid value, the program will respond with an e
alukav5142 [94]

Answer:

See explanation (Program written in C++)

Explanation:

The question is incomplete as the invalid values were not included in the question.

However, to make the sense of it, I'll answer your question using the following conditions.

1. Invalid values include: Numbers less than 0 (See comments for explanations)

#include <iostream>

using namespace std;

int main() {

//This line declares num (for user input)

int num;

//The following iteration keeps repeating itself until a number greater than 0 is entered using do while loop

do{

//This line prompts user for input

cout<<"Numbers greater than 0: ";

//This line gets input from the user

cin>>num;}

while(num<1);//This condition checks for valid user input

cout<<"You entered: "<<num; //This line prints out the user input

}

2. Invalid values include: Odd Numbers

I'll make use of the above code (in 1)

Start by replacing:

cout<<"Numbers greater than 0: ";

with

cout<<"Even Numbers: "; //This prompts user for even numbers

Replace

while(num<1);

with

while(num%2==1); //This checks if input is odd. If yes, the loop is repeated

3. Invalid values include: Even Numbers

I'll make use of the above code (in 1)

Start by replacing:

cout<<"Numbers greater than 0: ";

with

cout<<"Odd Numbers: "; //This prompts user for Odd numbers

Replace

while(num<1);

with

while(num%2==0); //This checks if input is even. If yes, the loop is repeated

Advantages of practicing safety in the information communication technology laboratory​
Svetllana [295]
Information communication technology (ICT) is a crucial tool to support effective communication and decision-making under complex and uncertain environments of disasters by enhancing cognitive capacity of emergency managers. With the continuous influence and evolution of communication technologies, information sharing and decision-making has drastically changed and affects each phase of emergency management. Researchers continue to investigate the relationship of human involvement for spreading public safety information through ICT. With each disaster holding diverse characteristics influencing prediction, detection, and specific activities required for prevention, mitigation, response and recovery, the need for interoperable and dependable communication infrastructure, a common operating picture, and supportive regulations, policies, and practice greatly increases. Although a national public safety communication system was proposed, there are implementation challenges between local, state, and federal agencies. This paper briefly examines the evolution of the use of ICT for public safety along with current trends, benefits and challenges, and future needs.
