need help for programming

[sweetbaby]

hello, i need the help for computer programming in the class.

the question is below. i try to write the program, but it comes out a lot of error. please, help me to do this problem.

Write a C++ program for the function

f1(x) = 2.6*x^3 - 5.7*x^2 + 4.9x - 15.3

Create an array with elements:

-4.3, 1.9, 2.5, -6.1, -9.5, 8.6, 7.2 , -11.3

Compute the value of f1(x) for each element of the array.
Display results in a table:

  element    value    f1(x)   
 --- --------------------------------------
    0        -4.3    

therefore, i start the program like

#include<iostream>
#include<iomanip>
#include<cmath>
using namespace std;

void msort(float y[],int);

int main()
{
const int size=8;
float arry[size]={-4.3, 1.9, 2.5, -6.1, -9.5, 8.6, 7.2 , -11.3},i;
cout<<"element: "<<size<<"value: "<<value<<"fl(x): "<<msort<<endl;
cout<<"----------------------------------------\n";
for (int i=0;i<10;i++)
cout<<setw(3)<<i ;
array(ary,size);
for(int i=0;i<size;i++)
cout<<setw(3)<<arry[i];
msort(arry,num);
for (int i=0;i<size;i++)
cout<<setw(3)<<arry[i];
cout<<endl;
return 0;
}

void msort(float list[],int x)
{
int i;
float x;
for (int i=0;i<size;i++)
{
f1(x) = 2.6*x^3 - 5.7*x^2 + 4.9x - 15.3
}
return 
}

Please use code tags.
^ in C++ is not number to the whatever power it is the bitwise OR. What you could do is write your own pow function eg.

float myPow(float value,int power)
{
  int i = 0;
  float tempValue = value;
  for(i = 1; i < power; i++)
  {
    
    value = value * tempValue;
    
  }
  
  return value;
}

As for your code if you want size to be global declare it outside of main, or you could pass it to msort as a const parameter. The rest I not going to bother reading cause its a pain without code tags
