寻找程序的错误，并改正：#include <stdio.h> #include <string.h> struct Workers { int num; char name[20]; }; void input(struct Workers a[]) {int i; for(i=0;i<10;i++) scanf("%d %s",&a[i].num,a[i].name); } void sort(struct Workers a[]) {int i,j; char b[20]; struct Workers temp; for(i=0;i<9;i++) for(j=0;j<9-i;j++) {if(a[j].num>a[j+1].num) {temp=a[j];a[j]=a[j+1];a[j+1]=temp; strcpy(b,a[j].name);strcpy(a[j].name,a[j+1].name);strcpy(a[j+1].name,b);} } void search(struct Workers worker[],int n) {int low = 0, high = 9, mid; while (low <= high) {mid = (low + high) / 2; if (worker[mid].num == n) { printf("职工号为%d的职工姓名为%s。\n", n, worker[mid].name); return; } else if (worker[mid].num > n) {high = mid - 1; } else { low = mid + 1; } } printf("无法找到职工号为%d的职工。\n", n); } int main() {int n=0; input(worker); sort(worker); printf("输入你要查找的工号："); scanf("%d",&n); search(worker); return 0; }

在 main 函数中，调用了 search 函数时，只传入了一个参数，但是 search 函数需要两个参数。正确的调用方式应该是：search(worker, n)。

另外，在程序开头定义了一个结构体 Workers，但是在 main 函数中没有定义结构体数组 worker，应该在 main 函数中定义一个结构体数组并传入函数中进行操作。完整代码如下：

#include <stdio.h>
#include <string.h>

struct Workers {
    int num;
    char name[20];
};

void input(struct Workers a[]) {
    int i;
    for(i=0; i<10; i++) 
        scanf("%d %s", &a[i].num, a[i].name);
}

void sort(struct Workers a[]) {
    int i,j; 
    char b[20]; 
    struct Workers temp;
    for(i=0; i<9; i++) 
        for(j=0; j<9-i; j++) {
            if(a[j].num > a[j+1].num) {
                temp = a[j];
                a[j] = a[j+1];
                a[j+1] = temp;
                strcpy(b,a[j].name);
                strcpy(a[j].name,a[j+1].name);
                strcpy(a[j+1].name,b);
            } 
        } 
}

void search(struct Workers worker[], int n) {
    int low = 0, high = 9, mid;  
    while (low <= high) {
        mid = (low + high) / 2;  
        if (worker[mid].num == n)  { 
            printf("职工号为%d的职工姓名为%s。\n", n, worker[mid].name);   
            return; 
        } else if (worker[mid].num > n) { 
            high = mid - 1;       
        } else { 
            low = mid + 1; 
        }          
    } 
    printf("无法找到职工号为%d的职工。\n", n);  
}

int main() {
    struct Workers worker[10];
    int n=0; 
    input(worker); 
    sort(worker); 
    printf("输入你要查找的工号："); 
    scanf("%d",&n); 
    search(worker, n);     
    return 0; 
}
