using namespace std;
int main(int argc, char *argv[])
{
ofstream out("test.txt");
out << 10 << " " << 123.23 << "\n";

2. Write a program that prompts user to enter:-
Name
Age
State
Country
and write into a file named biodata.txt as follows.
Name : Ahmad Ashraaf
Age : 19
State : terengganu
Country: Malaysia
3. The following program is supposed to read two numbers from a file named input.dat and write the sum of the numbers to a file named output.dat. However, it fails to do so. Rewrite the program so that it accomplishes whatit is intended to do. (Also, include statements to close the files.)
#include
#include
using namespace std;
int main()
{
int num1, num2;
ifstream infile;
outfile.open("output.dat");
infile >> num1 >> num2;
outfile << "Sum = " << num1 + num2 << endl;
return 0;
}
4. Assume that each of the following statements applies to the same program.
i) Write a statement that opens file oldmast.dat for input; use an ifstream object called inOldMaster.
ii) Write a statement that opens file trans.dat for input; use an ifstream object called inTransaction.
iii) Write a statement that opens file newmast.dat for output , use ofstream object outNewMaster.
iv) Write a statement that reads a record from the file oldmast.dat. The record consists of integer accountNumber, string name and floating-point currentBalance; use ifstream object inOldMaster.
