Random Number: Whenever I run it show me an error. Here is an error "implicit conversion loses integer precision 'time_t' (aka 'long') to 'unsigned int'", so i put change to `srand( (unsigned int) time(NULL) );` it run but it seem the number is not change at all.

``````void read_array (int read[] , int size1)
{
srand (time(NULL));
for (int index = 0; index < 30; index ++)
{
read[index]= rand() % 30 + 1;
}

}
``````

I am trying to find the mode but it didnt work! can someone help me out..

This is what i got so far

`````` for (int index = 0; index < size2; index ++)
{
//count[mode[index] - 1]++;
if (mode[index] == mode[index + 1]) // compare the first to sec array
{
again++;
cout <<"This is number " << again << endl;
}

}
``````

The mode is the number that appears the most often in the array. If the array contains {1,2,1,3,4,5,8} the mode is 1 because it appears twice and all others appear only once.

One way to calculate the mode is to use another 2d array, the first dimention contains a value from the original array and the second dimention contains a count of the number of times it appears in the original dimension.

Using the previous example data, the 2d array would contain

``````1  2
2  1
3  1
4  1
5  1
8  1
``````

Now all you have to do is select the value from the 2d array that has the largest count value.

I found the mode!!!

I need help with random number:

Everytime i run it the number look like doesnt change at all.

Here are one of the output

0-2-2-4-5-6-7-10-10-12
12-12-13-14-15-15-16-18-18-19
21-23-23-24-24-24-25-26-29-29

as you can see the number are same almost

what do you expect? Your pogram is generating 30 random numbers that are between 1 and 30.
