我几天前问过这个问题,但它并没有解决我的问题.我无法在Visual Studio中增加堆栈大小,我使用递归方法获得高输入并导致堆栈溢出.我不能使用矢量或其他东西.我需要的是在c ++,Visual Studio中增加堆栈大小.

PS我从Visual Studio配置增加了堆栈保留大小,但是,它也没有解决我的问题.

void sorting:: MergeSort(int *theArray, int n) {


    mergesort(theArray, 0, n - 1);

}
void sorting::mergesort(int *theArray, int first, int last) {
    if (first < last) {

        int mid = (first + last) / 2;   // index of midpoint

        mergesort(theArray, first, mid);

        mergesort(theArray, mid + 1, last);

        // merge the two halves
        merge(theArray, first, mid, last);
    }
}  // end mergesort
void sorting::merge(int* theArray, int first, int mid, int last) {
    const int max_size = …

当我编译它时,它说学生格拉德斯没有初始化.有什么问题？

#include <iostream>
    using namespace std;
    int takeGrade1(int *grades) {
        int i, noStudents;
        cout << "No of students: ";
        cin >> noStudents;
        grades = new int[noStudents];
        for (i = 0; i < noStudents; i++) {
            cout << "Enter the grade: ";
            cin >> grades[i];
        }
        return noStudents;
    }
    int main() {
        int *studentGrades, no, i;
        no = takeGrade1(studentGrades);
        cout << endl << "Grades: " << endl;
        for (i = 0; i < no; i++)
            cout << studentGrades[i] << endl;
        delete[]studentGrades; …
