不确定要在我的main中放入什么才能使我的代码正常工作

我写了这段代码，但不确定该在我的main((中放什么，如果有人能告诉我该怎么做，我会尽力想办法。这正是我想要做的：

• 程序描述了它应该做什么
• 提示用户输入1到10之间的数字，然后用正浮点数填充数组
• 使用函数输出浮点数组的内容
• 使用函数计算浮点数组的平均值、最大值和最小值。这些值在传递引用变量中返回
• 输出计算值
• 如果用户在任何时候输入了无效输入，请再次提示他们
• 安全终止

这是代码：

//include go here
#include <cstdio>
#include <iostream>
#include <cfloat>
using namespace std;

//Constants go here
const int MAX = 10;
const int MIN = 1

//outputs overview of program to user 
void displayOverview();

//prompts user to enter a number between min and max and return it
//validated using a loop
int getIntInRange(int min, int max);

//prompts user to enter a floating point number that is > 0
//validated using a loop
float getPositiveFloat();

//prompts user for size of array (< size)
//fills nums with that many floating point values
int fillArray(float nums[], int size);

//outputs the array
void printArray (float arr[], int Size);

//Computes and returns the mean, maximum, and minimum
void computesValues(float arrr[], int size, float &mean, float &max, float &min);

int main(){
displayOverview();

float myArr[MAX];
int size = fillArray(myArr, MAX);
return 0;
}

//Prompt user to enter a number between Min and max
//If user entered a number within the range, is valid is true
//If user entered a number not within min and max, output sorry not in range
int getIntInRange(int min, int max){
int userInput = -1;
bool isValid = false;
while(!isValid){
printf("Please enter an integer between %d and %dn", min, max);
scanf("%d", &userInput);
if(min <= userInput && userInput <= max){
isValid = true;
}else{
printf("Sorry, that is not in rangen Please try againn");
}
}
return userInput;
}

//int numVals
int fillArray(float nums[], int size){
int numVals = getIntInRange(MIN, MAX);
for(int i=0; i< numVals&& i<size ; i++){
nums[i] = getPositiveFloat();
}

return numVals;
}
//Prompt user to enter a positive number
//if User enters a number that is not positive, output "Not a Positive"
float getPositiveFloat(){
float input;
do{
cout << "Please enter a positive numbern";
cin >> input;
if(!(input>0)){
cout << "Not a positive!n";
}
}while(!(input>0));
return input;

}

//Introduction to the program
void displayOverview(){
cout << "Welcome to my program. You will see how magically I can compute things " << 
"from numbers!!" << endl;
}

//Print an array
void printArray(float arr[], int size){
for (int i = 0; i<size; i++){
cout << arr[i] << " ";
}
}

//Compute Min, max and mean.
void computesValues (float arr[], int size, float &mean, float &max, float &min){
float sum = 0;
for (int i = 0; i<size; i++){
sum = sum + arr[i]; 
}
mean = sum/size;
max = arr[0];
for (int i = 1; i<size; i++){
if(arr[i] > max)
max = arr[i];
}
min = arr[0];
for (int i = 1; i<size; i++){
if(arr[i] < min)
min = arr[i];
}
printf("mean = %f max = %f min = %fn", mean, max, min)
}
