一道考验细节的题
最后是？：运算符用错了
代码如下：
#include<stdio.h>
#include<string.h>
typedef struct Grade{int num;int inv;
}Grade;
Grade tmp[10];
int n, m, g, interval[10] = {0};int main(void)
{scanf("%d%d%d", &n, &m, &g);int num = 100 / m;for(int i = 0, grade; i < n; i++){scanf("%d", &grade);if(grade != 100)interval[(int)(grade / num)]++;elseinterval[m - 1]++;}//任务一if(g == 0 || g == 1){for(int i = 0; i < m; i++)tmp[i].num = interval[i], tmp[i].inv = i;for(int i = 0; i < m - 1; i++)for(int j = i + 1; j < m; j++)if(tmp[i].num < tmp[j].num || (tmp[i].num == tmp[j].num && tmp[i].inv > tmp[j].inv)){tmp[i].num ^= tmp[j].num ^= tmp[i].num ^= tmp[j].num;tmp[i].inv ^= tmp[j].inv ^= tmp[i].inv ^= tmp[j].inv;}//交换for(int i = 0; i < m; i++){if(tmp[i].num == 0) break;if(tmp[i].inv == m - 1)printf("[%2d,%3d]: %d\n", tmp[i].inv * num, (tmp[i].inv + 1) * num, tmp[i].num);elseprintf("[%2d,%3d): %d\n", tmp[i].inv * num, (tmp[i].inv + 1) * num, tmp[i].num);}}if(g == 0) putchar('\n');//任务二if(g == 0 || g == 2){int maxn = 0;for(int i = 0; i < m; i++)maxn = (maxn > interval[i]) ? maxn : interval[i];if(maxn > 50){for(int i = 0; i < m; i++)interval[i] = interval[i] * 50 / maxn;}for(int i = 0; i < m; i++){if(i == m - 1)printf("[%2d,%3d]:", i * num, (i + 1) * num);elseprintf("[%2d,%3d):", i * num, (i + 1) * num);for(int j = 0; j < interval[i]; j++)putchar('*');putchar('\n');}}return 0;
}
