c - c语言排序数组错误

Question

程序将每个球员的进球数写在排列好的列表中

在 C 语言代码中对数组进行排序在 Visual Studio 中显示错误“未计算为常量”。

int main() {

    int i,temp,swaped; 
    int howmany = 10;
    int goal[howmany];

    for (i = 0;i <= howmany;i++) {
        goal[i] = (rand() % 40)+1;
    }
    printf("orignal list");
    for (i = 0;i <= howmany;i++) {
        printf("%d \n", goal[i]);
    }
    while (1) {
        swaped = 0;
        for (i = 0;i < howmany;i++) {
            if (goal[i] > goal[i + 1]) {
                goal[i] = temp;
                goal[i] = goal[i + 1];
                goal[i + 1] = temp;
                swaped = 1;
            }

        }
        if (swapped == 0) {
            break;
        }

        printf("sorted list");
        for (i = 0;i < howmany;i++) {
            printf("%d \n", goal[i]);
        }
    }
    _getch();
    return 0;
}

Visual Studio 2013 有一个非常老旧的 C 编译器，即使经过这么多年，它仍然不理解 C99。所以你需要改变这个:

int howmany = 10;
int goal[howmany];

到:

#define howmany 10
int goal[howmany];
