Multimode//No mode?
Please support our C++ advertiser: Intel Parallel Studio Home
 |
after hours of trying (im really new to C++), i got a program to run that will find the mean, median, mode, and standard deviation of an array of numbers. However, if there is no mode (every number only appears once), it just returns the first number for mode. if there is more then one mode, it just returns the first mode. ive tried using a few if statements, but it screwed up everything and wouldnt run. ::points down:: this way will run. any suggestions on what i can do to make it happen?
//MODE HERE
int modeIndex=0;
int modeFrequency=0;
int maxModeIndex=0;
int maxModeFrequency=0;
for(int i=0 ; i<length ; i++)
{
if(list[i]!=list[modeIndex])
{
if(modeFrequency>1)
{
cout<< list[modeIndex] << " occurs " << modeFrequency << " number of times" << endl;
}
if(modeFrequency>maxModeFrequency)
{
maxModeIndex = modeIndex;
maxModeFrequency = modeFrequency;
}
modeIndex = i;
modeFrequency=1;
}
else
{
modeFrequency++;
}
}
// validate the last set of elements in the list.
if(modeFrequency>1)
{
cout<< list[modeIndex] << " occurs " << modeFrequency << " number of times" << endl;
}
if(modeFrequency>maxModeFrequency)
{
maxModeIndex = modeIndex;
maxModeFrequency = modeFrequency;
}
cout<< "Mode is: " << list[maxModeIndex] << endl;
return 0;
//MODE HERE
int modeIndex=0;
int modeFrequency=0;
int maxModeIndex=0;
int maxModeFrequency=0;
for(int i=0 ; i<length ; i++)
{
if(list[i]!=list[modeIndex])
{
if(modeFrequency>1)
{
cout<< list[modeIndex] << " occurs " << modeFrequency << " number of times" << endl;
}
if(modeFrequency>maxModeFrequency)
{
maxModeIndex = modeIndex;
maxModeFrequency = modeFrequency;
}
modeIndex = i;
modeFrequency=1;
}
else
{
modeFrequency++;
}
}
// validate the last set of elements in the list.
if(modeFrequency>1)
{
cout<< list[modeIndex] << " occurs " << modeFrequency << " number of times" << endl;
}
if(modeFrequency>maxModeFrequency)
{
maxModeIndex = modeIndex;
maxModeFrequency = modeFrequency;
}
cout<< "Mode is: " << list[maxModeIndex] << endl;
return 0;

the formatting is really horrible -- how did you get all those color code tags there? I just simply removed the code tags to make your code readable.

Don't PM me with questions -- you might get a nasty PM in response. If you have a question then post it in one of the forums.
the formatting of the c++ is horrible, as in the xyntax and logic? or how it copy/pasted?
i just opened up the .cpp file and copy/pasted. visual studio automatically colors my tags like that.

are you sure ? I've done it hundreds of times without that problem. Probably some setting you have made in the editor.

Oh certainly. It is how it appears in the forum -- no formatting and everything in the left-hand margin. Makes it really difficult to read and most people will probably just not take the time to fiture it out.
What version of Visual Studio are you using? I don't have that problem with 2005.

great work 
The green color is a result of code tags. Now we have something to study.

What behavior do you want it to do ?
