Matching parentheses. An math expression may have a number of parentheses like (, ), [, ], { and }. Each openning parenthesis (, or [, or { must be macthed by a corresponding closing parenthsis ), or ] or }. For example, 12 { 34 / [ 6 * ( 55 - 10 ) / ( 100 20 ) ] } has matched pairs of parentheses, while 12 { 34 / ( 6 * ) ] } does not. Write a function to check whether an input math expression has matched parentheses. The header of the function is given as follows:
bool match( const char exp [ ], const int s);
The input math express is store in the char array exp, and the size of exp is s. It returns true if all parentheses are matched or false otherwise.

Explanation:

Hope it helps

Answer:

#include <iostream>

int main() {

 // The length of the list

 int l;

 // The array containing the numbers

 int *list;

 // Threshold, last value in array

 int thresh;

 // Read in first value and create an array with the size of that value

 scanf("%d", &l);

 list = (int*) malloc(l * sizeof(int));

 for(int i = 0; i < l; i++) {

   scanf("%d", &list[i]);

 }

 thresh = list[l - 1];

 // Print the values

 for(int i = 0; i < l - 1; i++) {

   if (list[i] <= thresh) {

     printf("%d ", list[i]);

   }

 }

 printf("\n");

 free(list);

}

Explanation:

The program assumes at least two values are provided. The length of the list and the threshold.

We first read in an integer, and find out how many more integers we need to read. We create an array with the appropriate size, and loop through to fill the array with values. We know the last value is the threshold, and so we do one more loop to compare the values in the array with the threshold.

Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.

The Federal Financial Institutions Examination Council (FFIEC) is an interagency of government that was established on the 10th of March, 1979. FFIEC is saddled with the responsibility of developing the Cybersecurity Assessment Tool, which is then used as a self-assessment tool for identifying the maturity of a bank's or financial institution's cybersecurity.

Answer:

1.8 * 10^11 m

Explanation:

Given that :

Time taken for tweet to me posted after been sent, t = 10 minutes

t in seconds :

60 seconds = 1 minute

10 minutes = (10 * 60) = 600 seconds

Tweet sent will br transmitted at the speed of light, c = 3 * 10^8 m/s

Recall :

Speed = distance / time

Distance = speed * time

Distance of Curiosity from Earth = (3 * 10^8 * 600)

Distance of curiosity from earth = 1.8 * 10^11 m

Answer and Explanation:

function processNumbers(alist){

var Ourarray= new array(alist);

Ourarray.foreach(

if(isNaN()){

Console.log( "An element in the list is not a number."};

break;

}

}

processNumbers(alist)

From the above, we have defined a function that takes an array parameter(the following array variable will make sure of that). We test each element in the array using foreach array function. The for each function runs the if statement and if isNan is true for each of the elements in the array.

Answer:

The security principle being referred to here is:

Resource Encapsulation.

Explanation:

Resource Encapsulation is one of the cybersecurity first principles.  It allows access or manipulation of the class data as intended by the designer. The cybersecurity first principles are the basic or foundational propositions that define the qualities of a system that can contribute to cybersecurity.  Other cybersecurity first principles, which are applied during system design, include domain separation, process isolation, modularization, abstraction, least principle, layering, data hiding, simplicity, and minimization.

Answer:

The program is as follows:

#include <iostream>

#include <string>

using namespace std;

class Student{

string studName, indexNo, remarks; int marks;  char grade;

public:

 void getData(){

     cin.ignore();

     cout<<"ID: "; getline(cin,indexNo);

  cout<<"Name:"; getline(cin,studName);

  cout<<"Marks: ";cin>>marks;  }

 void calculate(){

  if(marks>=70 && marks<=100){

      remarks ="Excellent";       grade = 'A';   }

  else if(marks>=60 && marks<=69){

      remarks ="Very Good";       grade = 'B';   }

  else if(marks>=50 && marks<=59){

      remarks ="Pass";       grade = 'D';   }

  else{

      remarks ="Fail";       grade = 'F';   }

  cout << "Grade : " << grade << endl;

  cout << "Remark : " << remarks << endl;  }

};

int main(){

int numStudents;

cout<<"Number of students: "; cin>>numStudents;

Student students[numStudents];

for( int i=0; i<numStudents; i++ ) {

 cout << "Student " << i + 1 << endl;

 students[i].getData();

 students[i].calculate(); }

return 0;}

Explanation:

This defines the student class

class Student{

This declares all variables

string studName, indexNo, remarks; int marks;  char grade;

This declares function getData()

public:

 void getData(){

     cin.ignore();

Prompt and get input for indexNo

     cout<<"ID: "; getline(cin,indexNo);

Prompt and get input for studName

  cout<<"Name:"; getline(cin,studName);

Prompt and get input for marks

  cout<<"Marks: ";cin>>marks;  }

This declares funcion calculate()

 void calculate(){

The following if conditions determine the remark and grade, respectively

  if(marks>=70 && marks<=100){

      remarks ="Excellent";       grade = 'A';   }

  else if(marks>=60 && marks<=69){

      remarks ="Very Good";       grade = 'B';   }

  else if(marks>=50 && marks<=59){

      remarks ="Pass";       grade = 'D';   }

  else{

      remarks ="Fail";       grade = 'F';   }

This prints the grade

  cout << "Grade : " << grade << endl;

This prints the remark

  cout << "Remark : " << remarks << endl;  }

};

The main begins here

int main(){

This declares number of students as integer

int numStudents;

Prompt and get input for number of students

cout<<"Number of students: "; cin>>numStudents;

This calls the student object to declare array students

Student students[numStudents];

This is repeated for all students

for( int i=0; i<numStudents; i++ ) {

Print number

 cout << "Student " << i + 1 << endl;

Call function to get data

 students[i].getData();

Call function to calculate

 students[i].calculate(); }

return 0;}
