Answer:
#include <iostream>
#include <vector>
using namespace std;
void calGPA();
vector<int> g;
vector<int> h;
int main(){
char pushMore = 'y';
int fg, fh;
for (;;){
if (pushMore == 'n'){
break;
} else{
cout<< "Enter integer for grade: ";
cin>> fg;
cout<< "Enter integer for credit hours: ";
cin>> fh;
g.push_back(fg);
h.push_back(fh);
cout<< "Do you want to add more grade and credit hours? y/n: ";
cin>> pushMore;
}
}
calGPA();
}
void calGPA(){
double total = 0, GPA;
for (int i = 0; i < g.size(); ++i) {
total += g.at(i) * h.at(i) ;
}
cout<< "The GPA is : "<< total/g.size();
}
Explanation:
The C++ source code above defines two vectors 'g' and 'h'. The latter holds the grades of a student while the former holds the credit hours for the subject taken. The void 'calGPA' function calculates and prints the student's GPA.
Answer:
d. an element
Explanation:
User Interface design is simply the designs that are used to model a product like an application.
In a user interface, a screen is best understood as an element.
1.
#include <iostream>#include <string>
using namespace std;
int main(){ string chars; // This is where we will put our @ signs and print them for(int x=0;x < 5; x++){
chars = chars + '@'; // This will concatenate an @ sign at the end of the variable cout << chars << "\n"; }}

#include <iostream>#include <string>
using namespace std;
int main(){ string name; // Our variable to store the name cout << "What is your name? \n"; // Asks the user for their name cin >> name; cout << "\nWell, hello " << name << "!";}

#include <iostream>#include <string>
using namespace std;
int main(){ int number; // Our variable cout << "Enter a number\n"; // Asks for a number cin >> number; cout << "You entered " << number << "%!";}
4.
#include <iostream>#include <string>
using namespace std;
int main(){ int number; // Our variable cout << "Enter a number\n"; cin >> number;
int check = number % 2; // The modulo operator (the percent sign) gets the remainder of the quotient if (check == 0) { cout << number << " is even!"; // If the remainder is 0 then it prints out "x is even" } else { cout << number << " is odd!"; // If the remainder is not 0 then it prints out "x is odd" }}
5.
#include <iostream>#include <string>
using namespace std;
int main(){ float r; // Our variable cout << "Enter a radius\n"; cin >> r; if (r < 0){ cout << "Lol. No."; // If the radius is less than zero print out that message } float circumference=2*3.14*r; float area=r*r*3.14; cout << "\n\n Circumference of circle: " << circumference; cout << "\n Area of circle: " << area;}
