c语言实现输入n(n<100)的值,以及n个从小到大排序的整数序列,再输入一个待查找的整数m,使用二分法进行查找该数的序号。

这个问题属于技术问题，可以回答。以下是代码示例：

#include <stdio.h>

int search(int arr[], int n, int target) {
    int low = 0, high = n - 1;
    while (low <= high) {
        int mid = (low + high) / 2;
        if (arr[mid] == target) {
            return mid;
        } else if (arr[mid] > target) {
            high = mid - 1;
        } else {
            low = mid + 1;
        }
    }
    return -1;  // target not found
}

int main() {
    int n;
    printf("Enter the number of integers: ");
    scanf("%d", &n);
    if (n > 100) {
        printf("n is too large.\n");
        return 1;
    }
    int arr[n];
    for (int i = 0; i < n; i++) {
        scanf("%d", &arr[i]);
    }
    int m;
    printf("Enter the number to search: ");
    scanf("%d", &m);
    int result = search(arr, n, m);
    if (result == -1) {
        printf("%d not found.\n", m);
    } else {
        printf("%d found at index %d.\n", m, result);
    }
    return 0;
}
