在测试排序方法时,我遇到了selection sort。我已经理解了选择排序背后的逻辑,但是我没有从这个程序中得到我希望看到的结果。它看起来一点都不排序。谁能告诉我我哪里搞错了。
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int StudentCreation(int StudentRecordArray[10]){
for(int i = 0; i < 10; i++){
StudentRecordArray[i] = rand() % 100; //limiting the marks range from 0 - 100
}
}
int SelectionSort(int SelectionSortarray[]) {
int n = 0;
int tmp = 0;
for(int j = 0; j < 10-1; j++){
int TempMinimum = j;
for(int i = j+1; i < n; i++)
if(SelectionSortarray[i] < SelectionSortarray[TempMinimum])
TempMinimum = i;
if(TempMinimum != j){
tmp = SelectionSortarray[j];
SelectionSortarray[j] = SelectionSortarray[TempMinimum];
SelectionSortarray[TempMinimum] = tmp;
}
}
for (int f = 0; f < 10; f++){
printf("Student %d - %d\n", f+1, SelectionSortarray[f]);
}
}
int main() {
int StudentRecord[10];
int MenuChoice;
srand(time(NULL)); //random number seed generator
StudentCreation(StudentRecord);
printf("the unsorted list:\n");
for (int f = 0; f < 10; f++){
printf("Student %d - %d\n", f+1, StudentRecord[f]);
}
printf("\nthe sorted list:\n\n");
SelectionSort(StudentRecord);
return 0;
}我换的地方有问题吗?

排序函数中有一个拼写错误。
而不是
int n = 0;应该有
int n = 10;https://stackoverflow.com/questions/59703780
