Why doesn't my code to generate random unique numbers work in c++?

for(int i=1; i<=3; i++){
    for (int j=1;j<=3;j++){
        do{
            themap[i][j]=rand()%9 +1;
            for(c=1;c<=3;c++){
                for(int l=1;l<=3;l++){
                    if(themap[i][j]==themap[c][l] && (i!=c || j!=l)){
                        ok=1;
                    }
                }
            } 
        } while (ok==1);
    }
}

for(int k=1;k<=3;k++){
    for(int l=1;l<=3;l++){
        cout<<themap[k][l]<<"  ";
    }
    cout<<endl;
}

So I built this program. Basically, I wanted a 3x3 array that will have random numbers between 1 and 9, but different ones. For some reason, when I run the program it shows nothing on the screen. All declarations of variables were done. Can you please tell me what's wrong? Thanks!
