C++ Mode calculator problem (noob having problems)

[USN2ENG]

Homework Statement

Just as a background this is my first time ever learning to program. I am in an engineering C++ class. I had to write a program that took in ten random numbers and then found the mean median and mode. I got the first two and was able to figure out how to sort correctly. But now I am trying to set up a second array to count the number occurrences of the first array and I am getting a couple errors. I googled the errors but I am still not sure what it exactly means.

The Attempt at a Solution

My code snippet (if you need more, just let me know, I just didnt want to fill the whole page up):

int fakearray[10]={1,1,1,1,1,1,1,1,1,1};
int temp = 0;

for(int y=0; y < 10; y++)
{
temp=Bubble[y];
for(int x=0; x<10;x++){
if(Bubble[x]==temp){
int fakearray[y]= fakearray[y]++; //This is where all the errors are pointing
}
}
}

The errors I am getting:
error C2057: expected constant expression
error C2466: cannot allocate an array of constant size 0
error C2440: 'initializing' : cannot convert from 'int' to 'int []'
There are no conversions to array types, although there are conversions to references or pointers to arrays

Thanks to anyone that can help point me to the right path!

Haha, nevermind, I just realized I had int fakearray twice...well thanks if you looked!

Put your programs in [noparse]

[/noparse] tags to make them more readable.

Thanks! Will do next time, didn't know that was an option.

Hello there,

First of all, congratulations on taking on the challenge of learning a new programming language. It can be tough at first, but with practice and persistence, you will become more comfortable with it.

Now, let's take a look at the errors you are getting. The first one, "error C2057: expected constant expression" is indicating that you are trying to create an array with a size that is not a constant value. In your code, you have declared an array called "fakearray" with a size of 10, but then in the for loop, you are trying to declare another array with the same name and size. This is causing a conflict because you cannot have two arrays with the same name. Instead, you should use a different variable name for your second array, such as "count".

The second error, "error C2466: cannot allocate an array of constant size 0" is a result of the first error. Since you are trying to create an array with a size that is not a constant value, the compiler is unable to allocate memory for it and therefore, it has a size of 0.

The third error, "error C2440: 'initializing' : cannot convert from 'int' to 'int []'" is also related to the first error. In your code, you are attempting to assign a value to the array "fakearray[y]", but since it is not a constant value, the compiler does not know how much memory to allocate for it. Instead, you should use the count variable to keep track of the number of occurrences of each number.

I would also suggest using a nested for loop to iterate through both arrays and count the occurrences of each number. Something like this:

int count[10] = {0}; //initialize the count array with all 0s

for (int i = 0; i < 10; i++) {
for (int j = 0; j < 10; j++) {
if (Bubble[j] == Bubble) {
count++; //increment the count for that number
}
}
}

I hope this helps to clarify the errors you are getting and provides a possible solution to your problem. Keep practicing and don't be afraid to ask for help when needed. Good luck with your programming journey!
