One just indentation topic

[enemy]

Hello!
Please, is the first function ok indentated now? The problem is I saw many different types and I even don't know which of them are right and which not, so I am not able to learn from them...

    #include<iostream>
    using namespace std;
    
    int new_int(int a){
      cin>>a;
      return a;
    }

 
    int* f2(int z)
   {
      int* str=new int[40];
      int s=-1;
      srand(time(0));
     
      int zn=0;
     
      int random_integer;
      for(int index=0; index<10; index++){
      random_integer = (rand()%(z));
      str[index]= random_integer;
      cout<<"str["<<index<<"]="<<random_integer<<endl;
      s=s+1;
      zn=zn+random_integer;
      if (zn>3*z){
             cout<<"Last value is: "<<random_integer<<endl<<
             "Whole sum is: "<<zn<<endl<<"Index number: "<<s;
             break;
      }
     
    }
      return str;
      delete[]str;
    }
     
     
    void sort(int po[40], int do2)
   {
      for (int p=1; p < do2; p++) {
          for (int i=0; i < do2-p; i++) {
                   if (po[i] < po[i+1]) {
                     int temp = po[i];
                     po[i] = po[i+1];
                     po[i+1] = temp;
                   }
       }
    }

    for(int t=0;t<do2;t++){
    cout<<po[t]<<endl;}
    }
     
    int add(int po[40], int do3)
    {
      int all=0;
      for (int z=0;z<do3;z++){
        all=all+po[z];
        }
      return all;
}
    
     
    int main()
    {
      int amain;
      int doh=new_int(amain);
      int tre=doh/3;
      int vp=40;
     
      int* z;
      z=f2(tre);
     
       cout<<endl<<endl<<endl;
     
     
       // for(int h=0;h<40; h++) {cout<<z[h]<<endl;}
      sort(z, vp);
      cout<<"The whole sum: "<<add(z, vp)<<endl;
     
      delete[]z;
      return 0;
    }

Yes, that looks sensible to me.

There are various different styles you can use, and it's not too important which one you choose, as long as it's a sensible one and you're consistent in using it.

Doesn't your C++ textbook suggest an indentation style you can use?

Thanks, MikeBoy!:)

Better now ( I "tidied" it a little!)

What is the first mistake now?
