当我在 C++ 中运行我的函数时，为什么我的代码显示数字 53

Question

My friend created a program that prints a triforce to the console, however when he ran his code he realized that it printed weird numbers instead of what was supposed to run.

The code looks like this:

using namespace std;

#include <iostream>

void ZeldaTriangle(int Size){
    for (int  row = 0; row < Size; row++)
    {
        for (int spa = 0; spa < (Size-row-1); spa++)
        {
            cout << (" ");
        }
        for (int col = 0; col < (row +1); col++)
        {
            cout << ("@");
        }
        cout << "" << endl;
    }

}
void triforce_up (int Size, int character){
    for (int row = 0; row < (Size); row++)
    {
        for (int spa = 0; spa < (Size*2-row-1); spa++)
        {
            cout << (" ") << flush;
        }
        for (int col = 0; col < (row +1); col++)
        {
            cout << character << flush;
        }
        cout << "" << endl;
    }
}
void triforce_down (int Size, int character){
    for (int row = 0; row < (Size); row++)
    {
        for (int spa = 0; spa < (Size-row-1); spa++)
        {
            cout << (" ");
        }
        for (int col = 0; col < (row +1); col++)
        {
            cout << character;
        }
        for (int spa = 0; spa < ((Size-row-1)*2); spa++)
        {
            cout << (" ");
        }
        for (int col = 0; col < (row +1); col++)
        {
            cout << character;
        }
        cout << "" << endl;
    }
}
void print_ZeldaTriangle (int Size, int character){
    triforce_up (Size, character);
    triforce_down (Size, character);
}
int main() {
    int Size = 6;
    print_ZeldaTriangle(Size, '5');
}

It should display a triforce created with the number "5", but instead it shows this with the number 53.

           53
          5353
         535353
        53535353
       5353535353
      535353535353
     53          53
    5353        5353
   535353      535353
  53535353    53535353
 5353535353  5353535353
535353535353535353535353

I have attempted to change the "int character" to "string character" in order to prevent the error from happening but that displays a broken triforce that looks nothing like it should look like.

           5
          55
         555
        5555
       55555
      555555
     5          5
    55        55
   555      555
  5555    5555
 55555  55555
555555555555

Answer 1

"void ZeldaTriangle(int Size)"

You don't need this function

when you convert char to int

your output is somewhat like this:

5                    5
55       or         55
555                555
5555              5555
55555            55555
555555          555555

then your code is correct Syntactically it is printing what it is meant to print. but logically you yourself is lacking basic imagination.

• either you can insert spaces in between or insert extra value to it

if you want output either like this or that...

     5                              5
    5 5                            555
   5 5 5                          55555
  5 5 5 5                        5555555
 5 5 5 5 5                      555555555
5 5 5 5 5 5                    55555555555

your code is good the only thing you need is some result imagination:)

i have simplified the code: https://repl.it/repls/FluffyMildMenu

And about the "53" error i don't know for sure but I think it is related to some charcater converted to int inside the code..

Answer 2

You are passing 5 as char but your functions accept integer value. When you pass a char value your functions will use ASCII value as int value. If you look at ASCII table '5' represents 53. Please refer link below: https://www.ascii-code.com/

Answer 3

I guess, as you are expecting in in the

print_ZeldaTriangle (int Size, int character) {

}

and inputing this

print_ZeldaTriangle(Size, '5');

The char is converted to int, which is bad as Char 5 when converted to int is 53 See this table for reference https://www.cs.cmu.edu/~pattis/15-1XX/common/handouts/ascii.html

So, to fix this, do this

int main() {
    int Size = 6;
    print_ZeldaTriangle(Size, 55);
}

EDIT:- Do 55, instead of 5

Answer 4

53 is the ASCII value of character '5', change function signature to

 void triforce_up (int Size, char character)
 void triforce_up (int Size, char character)
