程序代码：

#include<iostream>
using namespace std;
int main()
{
    char a[]{"The string consisting of something."};
    char b[]{"sting"};
    int c[10];
    int i{}, j{}, k{};
    while (a[i])
    {
        if (a[i] == 's')
            c[j] = i;
        i++; j++;
    }
    i = 0; 
    for (auto k : c)
    {
        j = 0;
        for (i = k; i < k + 5; i++)
        {
            if (a[i] != b[j])
                break;
            j++;
        }
        if (j == 5)
            cout << k;
    }

    return 0;
