 |
|
well, i cant seem to take the loop information i get and stick it in the .txt
im using fstream I/O to write the file (ofstream)
this is CLR btw
this is the code snippet of the I/O im using
| Code: | ofstream myFile("specs.txt", ios::app);
if (myFile.is_open())
{
myFile << "Starting Sum: " << ssum << "\nInterest: " << irst << "\n\n\n";
myFile << "Day: " << ++day << "\nMoney: $" << ssum + (irst * day) << "\n\n";
myFile.close();
}
else { cout << "Unable to open Text Document"; } |
now the | Code: | | "Day: " << ++day << "\nMoney: $" << ssum + (irst * day) << "\n\n"; |
is obviously the loop, but i cant seem to get the loop into the txt document.
all together the loop is:
| Code: | while (day > 365)
{
cout << "Day: " << ++day << "\nMoney: $" << ssum + (irst * day) << "\n\n";
} |
helps appreciated...
the program asks u for your starting sum, then the daily interest, then the loop is supposed to show everyday's money. but obviously the CLR box isnt big enough. so a .txt document is my only choice
Edit: oh yea, before i forget, is there a way to increase by percent in C++, ive searched around but have found nothing.
% = modules (remainder) so theres nothing else i can think of accept for maybe deviding the number by 100 then multiplying by the percent

that works to me
| Code: |
#include <windows.h>
#include <iostream>
#include <fstream>
using std::cin;
using std::cout;
using std::ofstream;
int main()
{
int day = 0;
int ssum;
int irst;
ofstream myFile("specs.txt", std::ios::app);
cin >> ssum >> irst;
if (myFile.is_open())
{
myFile << "Starting Sum: " << ssum << "\nInterest: " << irst << "\n\n\n";
while (day < 365)
{
myFile << "Day: " << ++day << "\nMoney: $" << ssum + (irst * day) << "\n\n";
}
myFile.close();
}
else { cout << "Unable to open Text Document"; }
return 0;
