using an if inside a for loop

hi ppl!
im here again with another problem, which, is more a question about if what im doing is ok.

the thing is i have to do a problem that counts the total of letters sent, the total of packages sent, total of letters and packages sent on the next day priority, on the next day normal, and the total if its sent over 2 days.
also i have to calculate a big total of letters and packages sent (i mean letters + packages in each day) and the percentage of the total of things sent on the next day priority, of the next day normal, and over 2 days.

i already have a code made, my question if its ok to put a for loop in the middle of a chain of ifs:

C++ Syntax (Toggle Plain Text) 
  1. //A GENERAL FOR LOOP WOULD BE HERE
  2. if ((peso < 30) && (dia = 7))                    
  3.        cout << " Se le cobraran 8$ " << "\n";                // these 3 are letters, 
  4. else if ((peso < 30) && (dia = 8))               
  5.       cout << " Se le cobraran 5$ " << "\n";
  6. else if ((peso < 30) && (dia = 9))
  7.        cout << " No esta disponible$ " << "\n";
  8. //ANOTHER PUT A FOR LOOP HERE
  9.               else if ((peso > 30) && (peso < 1000) && (dia = 7))         // from here to the end, are packages
  10.                      cout << " Se le cobraran 25$ " << "\n";
  11.               else if ((peso > 30) && (peso < 1000) && (dia = 8))
  12.                      cout << " Se le cobraran 20$ " << "\n";
  13.               else if ((peso > 30) && (peso < 1000) && (dia = 9))
  14.                      cout << " Se le cobraran 15$ " << "\n";
  15.       //AND ANOTHER ONE HERE
  16.                             else if((peso > 1000) && (dia = 7))
  17.                             {
  18.                                    cout << " Se le cobraran 25$ " << "\n";
  19.                                    cout << " Y 2$ adicionales por cada 500 gr de màs" << "\n";
  20.                                    diferencia = ((peso-1000) / 500);
  21.                                    total_a_pagar = (25 + ((diferencia *2) + 2));
  22.                                    cout << " Se le cobraran" << total_a_pagar << " $ en total" << "\n";
  23.                             }
  24.                             else if ((dia = 8) && (peso > 1000))
  25.                             {
  26.                                    cout << " Se le cobraran 20$ " << "\n";
  27.                                    cout << " Y 1.5$ adicionales por cada 500 gr de màs" << "\n";
  28.                                    diferencia = ((peso-1000) / 500);
  29.                                    total_a_pagar = (25 + ((diferencia *2)+2));
  30.                                    cout << " Se le cobraran" << total_a_pagar << " $ en total" << "\n";
  31.                             }
  32.                             else if ((dia = 9)&& (peso > 1000))
  33.                             {
  34.                                    cout << " Se le cobraran 15$ " << "\n";
  35.                                    cout << " Y 1$ adicionales por cada 500 gr de màs" << "\n";
  36.                                    diferencia = ((peso-1000) / 500);
  37.                                    total_a_pagar = (25 + ((diferencia *2)+2));
  38.                                    cout << " Se le cobraran" << total_a_pagar << " $ en total" << "\n";
  39.                             }

what i want to do is this: the program must consider the hours in which the people work, so the first for loop would control that [for (hour = hour_begining; (hour > hour_begining) && (hour < hour_final); hour++) ]. now, when it comes to the other two for loops, i dont know if they will stop in any way the ifs, or do i have to write the code differently.

in the code:
peso = weight
dia = day
total_a_pagar = is what i have to pay if i send just one (its calculated only for the packages, if its a letter doesnt matter the weight, its a fixed price)



thanks for the help!!
gispe!!

ps: if anything isnt clear, ask me! and if whole code were necessary ill paste it!!

If we asked for more code, would you still post it without [code][/code] tags?

Salem meant you should wrap your code in code tags (the # button on the top, or just type [ code] YOUR CODE HERE [/code], w/o the spaces between '[' and "code").

Do you want the for loop to be part of this conditional:
C++ Syntax (Toggle Plain Text) 
  1. else if ((peso > 30) && (peso < 1000) && (dia = 9))
  2. cout << " Se le cobraran 15$ " << "\n";
  3. //for loop only executed if peso is between 30 and 1000 and dia is 9

If so, just wrap the code in curly brackets:
C++ Syntax (Toggle Plain Text) 
  1. else if ((peso > 30) && (peso < 1000) && (dia = 9))
  2. {
  3.     cout << " Se le cobraran 15$ " << "\n";
  4.     for(;;)
  5.     //your loop here
  6. }
  7. //next else if condition

If you meant that the loop is executed regardless of the above conditional, you can also do that, though the else if after it would need to become a regular if:
C++ Syntax (Toggle Plain Text) 
  1. /*else*/if((peso > 1000) && (dia = 7))

I'm a student. If my statements seem too absolute, feel free to coat them with "In my opinion..." or "I believe...".

Yes it's ok. Try put it in and see what happens. If it messes up it's the logic that's wrong.

  79. 			diferencia = ((peso-1000) / 500);
  80. 			total_a_pagar = (25 + ((diferencia *2)+2));
  81. 			cout << " Se le cobraran" << total_a_pagar << " $ en total" << "\n";
  82. 		}
  83. 	}
  84.  
  85. 	system ("PAUSE");
  86.  
  87.  
  88. 	return 0;
  89. }

Sorry for "bumping" this thread, but it really gave me a headache to see the code like this and I'm sure it's giving other people a headache too.

Use code tags please! People will be more inclined to help when you do.

so, u mean that i should put the for inside the if, n wont modify the ifs instructions?

cuz i have to count the letters sent every day, and then sum it up

Please don't use leet-speak. He's asking whether the for-loop should always be executed, regardless of whether the if-condition is true. If it should always be executed, then don't put the for-loop inside the if-statement. If the for-loop should only be executed if the the if-condition is true, then put the for-loop inside the if-statement's brackets.

I don't understand what you mean by this sentence, the red part in particular.

Do you mean "execute" rather than "modify"? The machine code instructions can't be modified when you run the program.

well, im back here: same program.
i made some modifications n now runs, but the thing is that it puts on screen same message indefinitely.

it reads the hours it worked, what i want to send (package or letter), and the day i want to send it. n then it returns the cost (indefinitely).

there is the code attached, if u want to try it
