C++ For loop loops only 299 times
I'm having this weird problem. My code is simple:
#include <iostream>
using namespace std;
int main() {
int num;
c开发者_开发百科out << "number: ";
cin >> num;
for (int i=0;num>i;i++) {
cout << i <<"\n";
}
system ("Pause");
return 0;
}
If the input for example is 1000, the output contains numbers from 701-999. Any idea?
I'm using Dev-C++ IDE on Parallels.
Actually it prints all of them, from 0 to 999, but your console's buffer is not large enough. So you see only the last part. if you print into a file, not the console, you'll see :)
The loop ends when num>i
is no longer true. This occurs when i is 1000, so the last loop executed will be with value 999. As for not seeing lower than 701, maybe your screen buffer is too small.
It will start with 0-999. Also, it appears to you that it starts with 701 because of your console screen settings. If you want to see it for yourself, change the newline into a space:
cout << i <<" ";
Did 0-700 scroll off the screen? Run your exe like this
your_program > out.txt
Then look at out.txt in an editor.
Works absolutely fine for me. I'd suggest your IDE might be playing tricks on you. Could you redirect output into a file and check that?
Regarding @JoshD answer, You will need to:
for (int i=0;num>=i;i++) {
cout << i <<"\n";
}
