Answer:
#include <iostream>
using namespace std;
int main() {
int age,time;
float price;
cout<<"Enter age:";
cin>>age;
cout<<"Enter time(in 24 hour clock for noon 1200):";
cin>>time;
if(age>13){
if(time<1700){
price=5;
}else{
price=8;
}
}else{
if(time<1700){
price=2;
}else{
price=4;
}
}
cout<<"Price: $"<<price<<endl;
}
Explanation:
Okay, here are the steps to be taken in order to be able to Write a program that determines the price of a movie ticket as given in details in the question above. Therefore, checked the steps below;
==> Input the age and the time.
==> If the age is not greater than 13, input the time(that is <1700) and follow it by imputing the price.
And if the age is greater than 13, you will also need to input the price. Just as below;
#include <iostream>
using namespace std;
int main() {
int age,time;
float price;
cout<<"Enter age:";
cin>>age;
cout<<"Enter time(in 24 hour clock for noon 1200):";
cin>>time;
if(age>13){
if(time<1700){
price=5;
}else{
price=8;
}
}else{
if(time<1700){
price=2;
}else{
price=4;
}
}
cout<<"Price: $"<<price<<endl;
}
Answer:
B

I choose b and it was correct
If the requirement is to erase all the data from the hard disk drive on the Mac, then it's best to use a tool known as the Disk Utility. This will delete all the files and volumes on the hard drive. The Disk Utility offers four options:
1. Don't erase data2, Zero out Data3. 7-Pass Erase4. 35-Pass Erase
On the other hand, if the requirement is to delete individual files, then the best thing to do is to highlight the file you want to delete, right-click on it and "Move to trash".
Answer:
/*C++ program that prompts user to enter the name of input file(input.txt in this example) and print the sum of the values in the file to console. If file dosnot exist, then close the program */
//header files
#include <fstream>
#include<string>
#include <iostream>
#include <cstdlib> //needed for exit function
using namespace std;
//function prototype
int fileSum(string filename);
int main()
{
string filename;
cout << "Enter the name of the input file: ";
cin >> filename;
cout << "Sum: " << fileSum(filename) << endl;
system("pause");
return 0;
}
/*The function fileSum that takes the string filename and
count the sum of the values and returns the sum of the values*/
int fileSum(string filename)
{
//Create a ifstream object
ifstream fin;
//Open a file
fin.open(filename);
//Initialize sum to zero
int sum=0;
//Check if file exist
if(!fin)
{
cout<<"File does not exist ."<<endl;
system("pause");
exit(1);
}
else
{
int value;
//read file until end of file exist
while(fin>>value)
{
sum+=value;
}
}
return sum;
}//end of the fileSum
Explanation:
This is a C++ program that prompts user to enter the name of input file(input.txt in this example) and print the sum of the values in the file to console. If file dosnot exist, then close the program.
