如何正确格式化

我正在执行"随机漫步"程序，无法正确显示条形图。

这是我的代码（我只会包括我需要帮助的内容）：

#include <iostream> 
#include <conio.h>
#include <string>
#include <ctime>
#include <random>
using namespace std;
int main() {
    srand(time(0)); // make it "random"
    int max;
    int min;
    int location; //location of goat on bridge
    int steps;
    int total_steps;
    int choice;
    int move; // go forward or backward
    for (;;) {  // Keep running until user quits
        system("CLS");
        cout << "Random Walk Simulator" << endl;
        cout << "1) Display Trial " << endl;
        cout << "2) Run Statistics Over 50 Trials " << endl;
        cout << "3) Quit. " << endl;
        cin >> choice;  // get choice
        cout << "n";
        if (choice == 1) {  // Display Trial
            steps = 1;
            location = 4;  // center of bridge
            cout << "Step 0: |   *   | " << endl;
            while (location >= 1 && location <= 7) {  // Keep running until goat falls off bridge
                move = rand() % 2 + 0;  // 0 and 1
                if (move == 0) {  // Move backward
                    location--;
                }
                if (move == 1) {  // Move forward
                    location++;
                }
                switch (location) {  // Show location
                case 0: cout << "Step " << steps << ": |       | " << endl;
                    break;
                case 1: cout << "Step " << steps << ": |*      | " << endl;
                    break;
                case 2: cout << "Step " << steps << ": | *     | " << endl;
                    break;
                case 3: cout << "Step " << steps << ": |  *    | " << endl;
                    break;
                case 4: cout << "Step " << steps << ": |   *   | " << endl;
                    break;
                case 5: cout << "Step " << steps << ": |    *  | " << endl;
                    break;
                case 6: cout << "Step " << steps << ": |     * | " << endl;
                    break;
                case 7: cout << "Step " << steps << ": |      *| " << endl;
                    break;
                case 8: cout << "Step " << steps << ": |       | " << endl;
                    break;
                default: break;
                }
                steps++;  // Iterate steps
            }
            cout << "nTotal steps taken: " << (steps - 1) << endl; // (steps-1) since I start the goat off at the center of the bridge
            system("PAUSE");
        }

以下是输出示例：

Random Walk Simulator
1) Display Trial
2) Run Statistics over 50 Trials
3) Quit 
1
Step 0: |   *   |
Step 1: |    *  |
Step 2: |     * |
Step 3: |    *  |
Step 4: |   *   |
Step 5: |    *  |
Step 6: |   *   |
Step 7: |  *    |
Step 8: |   *   |
Step 9: |    *  |
Step 10: |   *   |
Step 11: |  *    |
Step 12: | *     |
Step 13: |*      |
Step 14: |       |

如何正确格式化？对不起，我对C++有点陌生。
