解题思路：先将首字母变成大写，然后每当遇到空格且空格后面是字母，则将字母变成大写。

#include <iostream>
using namespace std;

int main() {
    char s[500];
    while (gets_s(s) != NULL) {
        int len = strlen(s);
        if (s[0] >= 97 && s[0] <= 122)
            s[0] -= 32;
        for (int i = 0; i < len; i++) {
            if (s[i] == 32 && (s[i + 1] >= 97 && s[i + 1] <= 122))
                s[i + 1] -= 32;
        }
        cout << s << endl;
    }
    return 0;
}
