expected primary-expression before 'float' and expected ';' before 'float'

Hi,I have 2 errors on the same line while compiling this code, I know itmay be some common beginners errors. Thank you in advance to any onewho may help me

Code:

Code:

#include <iostream>     
#include <iomanip>       
#include <cstdlib>      
using namespace std;
float grilletest[20][20];

float initialisation_grille()
{
   float grille[20][20];
   int ligne ; int colonne ;
   for ( ligne = 0 ; ligne <= 20 ; ligne ++ )
        {  for ( colonne  = 0 ; colonne <= 20 ; colonne ++ )
                    {  grille [ ligne ] [ colonne ] = '0' ;
                        }


                }
return grille[20][20];
}

void affichage_grille ( float grilletest[20][20] ) { 
float toto[20][20];                                                                   
toto= float initialisation_grille();


 int ligne ;
 int colonne ;
 for ( ligne = 20; ligne >=0 ; ligne --){
                                            for ( colonne = 0 ; colonne <= 20; colonne ++ ){
                                            cout<< toto [ ligne ] [ colonne]<<'\t' ;
                                                    }
      cout << endl ;
    }
}




int main(){
float tata[20][20];
initialisation_grille();
affichage_grille (tata);
}

1. Your indentation needs work.

Code:

#include <iostream>
#include <iomanip>
#include <cstdlib>
using namespace std;
float grilletest[20][20];

float initialisation_grille()
{
  float grille[20][20];
  int ligne;
  int colonne;
  for (ligne = 0; ligne <= 20; ligne++) {
    for (colonne = 0; colonne <= 20; colonne++) {
      grille[ligne][colonne] = '0';
    }
  }
  return grille[20][20];
}

void affichage_grille(float grilletest[20][20])
{
  float toto[20][20];
  toto = float initialisation_grille();

  int ligne;
  int colonne;
  for (ligne = 20; ligne >= 0; ligne--) {
    for (colonne = 0; colonne <= 20; colonne++) {
      cout << toto[ligne][colonne] << '\t';
    }
    cout << endl;
  }
}

int main()
{
  float tata[20][20];
  initialisation_grille();
  affichage_grille(tata);
}

2. What's this supposed to be?
toto = float initialisation_grille();

No, you can't return a whole array and assign it to another array.

If you want to initialise your array, pass it as a parameter.

3. for (ligne = 0; ligne <= 20; ligne++)
All your loops are array overruns.

Typically, you do
for (ligne = 0; ligne < 20; ligne++) // NOT <=
