我正在撰寫一個程式，它在堆上動態分配一個陣列，用 55-99 的亂數填充它并將它們列印成 10 行。我使用了 9 個以上的動態陣列來存盤這些行中的每一行。但是在運行程式時出現錯誤：正常塊后檢測到堆損壞。我很抱歉笨拙的代碼。
#include <iostream>
#include <algorithm>
#include <ctime>
using namespace std;
int numScores = 199;
int* randomTestScores = new int[numScores];
void fillArray() {
for (int i = 0; i < 199; i ) {
const int min_Value = 55;
const int max_Value = 99;
randomTestScores[i] = (rand() % (max_Value - min_Value 1)) min_Value;
}
}
void sortArray() { std::sort(randomTestScores, randomTestScores numScores); }
// Created better varibale names than a, b, c, etc.
int s5559 = 0, l5559 = 0;
int s6064 = 0, l6064 = 0;

uj5u.com熱心網友回復：
你在這些陳述中有一個錯字
if (randomTestScores[i] >= 80 && randomTestScores[i] <= 84) {*(testScores7579 l8084) = randomTestScores[i]; l8084 ;}
if (randomTestScores[i] >= 85 && randomTestScores[i] <= 89) {*(testScores7579 l8589) = randomTestScores[i]; l8589 ;}
if (randomTestScores[i] >= 90 && randomTestScores[i] <= 94) {*(testScores7579 l9094) = randomTestScores[i]; l9094 ;}
if (randomTestScores[i] >= 95 && randomTestScores[i] <= 99) {*(testScores7579 l9599) = randomTestScores[i]; l9599 ;}
不同的索引使用相同的陣列。
