Hi everybody ! I get this error

no match for 'operator<<' in 'std::cin 1935374429'

while compiling this code :

Code:

---

#include <iostream>
#include <iomanip>
#include <cstdlib>


using namespace std;




void initArray(float largeArray[6][6]){
    for (int x=0; x < 6; x++){
            for (int y=0; y<6; y++){
                  largeArray[x][y] = 0;
        }
    }




}




float printOutArray(float largeArray[6][6]){
    for (int x = 0; x < 6; x++){




            for (int y = 0; y < 6; y++){
                    cout << largeArray [x] [y]<<'\t';
                }
          cout << endl;
        }
return largeArray[6][6];
}


void tata (int degree_denominator, float largeArray[6][6] ){
float array_of_coefficients[6];
int c=0;
int l=0;
int x=0;
for (x=degree_denominator ; x>=0 ; x--){
                                        if (l==1){l=0;c++;}
                              cout << "what is the coefficient linked with degree" <<x<< "?" << endl;
                              cin << array_of_coefficients[x];
                              largeArray[l][c] = array_of_coefficients[x];
                              l++;
                                  }
}


int main()
{
    float largeArray [6][6];
    initArray(largeArray);
    printOutArray(largeArray);
    int degree_denominator;
    cout << "what is the degree of the denominator?" << endl;
    cin >> degree_denominator;
    tata(degree_denominator, largeArray);


}

My error is in my function "tata" at the line where the cin is.
I have no clue where this error comes from, if someone could tell me something to delete this error i would greatly appreciate it

> cout << "what is the coefficient linked with degree" <<x<< "?" << endl;
> cin << array_of_coefficients[x];
Which way round should >> and << be?

What a stupid beginner error!! OK thank you i have to write : cin >> array_of_coefficients[x];

Think of it like this:

With "cin >> myvariable" the data moves from stdin to the variable. With "cout << myvariable" the data moves from the variable to stdout. So the flow always follows the directions of the arrows/stream operators. That's an easy way to remember it.
