我这里应该怎么改，求各位帮帮忙！

修改如下,有帮助望采纳

#include <iostream>
using namespace std;
int search(int* A, int n, int k)
{
    int i = 0;
    while (i <= n - 1)
        if (A[i] != k)
            i++;
        else
            break;
    if (i <= n - 1)
        return 1;
    else
        return -1;
}
int main()
{
    int n = 5;
    int A[n] = {1, 2, 3, 4, 5};
    int k = 7;
    int Search = search(A, n, k);
    cout << Search;
}
