Bonjour
SVP je suis bloqué j'arrive pas à comprendre mes fautes
je suis en train de compiler ce programme pour dessiner une matrice adjacente.

    int i,j;
cout<<"\n\n"<<setw(4)<<" ";

cout<<setw(3)<<"("<<i+1<<")";
for(j=0;j<n;j++){
cout<<setw(4)<<mat[i][j];
}
 cout<<"\n\n";
    }
main(){
int i,j,v;
cout<<"enter the number of vertexes:";
cin>>v;
int mat[10][10]
cout<<"\n";
//Take input of the adjacency of each pair of vertexes.
for(i=0;i<v;i++){
    for (j=i;j<v;j++){
        if(i!=j){
            cout<<"enter 1 if vertex"<<i+1<<"is adjacent to"<<j+1<<" , otherwise 0: ";
            cin>>mat[i][j];
            mat[i][j]=mat[i][j];
        }
        else 
        mat[i][j]=0;
    }
}
 
        PrintMat(mat,v);
        return 0;
}
 
//Lets run the program.
