i went to the source code page, and downloaded the .zip file for the triangle program. its one of the programs in the first box on the source code page, but when i open it, i cant read the code because this error comes up:
Windows cannot find 'C:\Users\Aaron Silman\Downloads\triangle.zip\triangle.cpp'. Make sure you typed the name correctly, and try again.
then i click the OK box, and this message box comes up
Windows cannot complete the extraction.
The destination file could not be created
why cant i view this code? i am using visual studios 2005. This happens for all the source code i try to download
The sourcecode downloads work on my computer (I've noticed that it didn't work some time ago but it was fixed after a while)
You just need to unzip the file before viewing in with Visual Studio

int width; // width is how far to go into the center of screen
int base; // base is how many symbols are on bottom line

width = (base / 2) + 5 - counter; // This is how far into the center it should space until it starts outputting the symbol
// It must first be given a value before it enters the loop
a = 1; // a is how many lines down the triangle is, and natuarally it starts on the first line
while(width > 5) // It will loop and continue to output the symbol until it reaches 5 spaces from the left margin...
// so that everything isn't jammed against the side
{
width = (base / 2) + 5 - counter; // This is how far into the center it should space until it starts outputting the symbol
cout<<setw(width); // setw is an output manipulator in the <iomanip.h> library. this tell the compiler how many lines
// to move until it first sends a character to the screen. It is currently set to move the value of
// "width" spaces to the right before it outputs.
while(b > 0) // This while loop will continue to output the desired symbol to the current line until it is equal to 1
{
cout<<letter; // outputs the letter or symbol entered
b--; // b is decremented so only so many letters are outputted per line
}
cout<<endl; // an endl is used to jump to the next line to output the next part of the triangle
b = (a * 2) - 1; // the number of symbols per line is found using this equation
width--; // the width is decremented so that everything is spaced properly
b = b + 2; // b is given 2 more symbols because it is on the next line, and every line has 2 more than the previous
a++; // this is how many lines into the triangle it is
counter++; // the counter is used to ensure proper spacing done by the width variable
}
cout<<endl<<endl; // endl is used to add some space between each time the program is executed
b = 1; // b is returned to 1 because the program started over
counter = 0; // counter is returned to 0 because the program started over

return 0;
}
Notice that you may need to change lines 7-8 removing the .h and use std namespace
