C++ emergency need this word doc to be done and i can't do it my self cause it bit to hard for me plz help

Write a program to survey people, that will generate statistics about their age profile.
It will firstly ask for the sample size. Then it will ask you to enter the ages of every person in the sample. Once the data entry is complete the program should output:

the total age
the average age
the standard deviation
the median

plz help

``````#include <iostream>
#include <math.h>
using namespace std;

int main();
{
void showMedian(int array, int size);
//Declare variabels
int i;
int x;
int middle;
double age;
double total = 0;
double average = 0;
double variance;
double sd = 0;
double scores[i];
double temp = 0;
double median = 0;

//main program loop

cout << "how many: ";
cin >> x;

//get the input
for(x=0;x<=100;x++)
{
for(i=0;i<=100;i++)
{
if(scores[i]>scores[i+1])
{
temp=scores[i];
scores[i] = scores[i+1];
scores[i+1] = temp;
}
}
}
//the median input and output

middle = size / 2;
if ( middle % 2)
{
average = ((array[middle]) + (array[middle + 1])) / 2;
cout << "The median is: " << average << endl;
}
else
{
cout << "The median is: " << (array[middle + .5]) << endl;
}

for(i=0;i<=99;i++)
{
cout << "Enter an age: ";
cin >> age[i];
total = total + age[i];
}

average = total / 100;

for(i=0;i<=99;i++)
{
variance[i] = (scores[i] - average);
total = total + (variance[i]*variance[i]);
}

cout << "Total: " << total << endl;
cout << "median: " << median << endl;
cout << "Average: " << average << endl;
cout << "Standard Deviation: " << sd << endl;
cout << "Again: " << endl;

system ("pause");
system("cls");
return 0;
break;
}``````

plz help

Did you mean for the parameter called "array" to be just an integer or an actual int[]?

as a integer

...then referencing it as "(array[middle]) " will give an error, yes?

yes thats right

Functions cannot be defined or declared inside of other functions.

Use this for reference:

``````#include <iostream>
using namespace std;

//Below is a function prototype or "declaration"
void ShowMessage();

//Entry-point.
int main()
{
ShowMessage();
//Compiler inserts "return 0;" automatically.
}

//Function body or "definition"
void ShowMessage()
{
cout << "Hello, CPP world." << endl;
}``````

Also note that the entry-point is a definition only, but is still a function.
