Question

比如说我的输出是：thwhglHDGQYE836

有没有办法把它作为输出混淆？如果有办法，一些建议会很好，谢谢:)。

#include <stdlib.h>
#include <stdio.h>
#include <time.h>

int main(void) {
    int i;
    char c;

    srand(time(NULL));
    printf("Your Random Password is: ");
    for (i = 0; i < 6; ++i) {
        c = 'a' + rand() % ('z' - 'a' + 1);
        printf("%c", c);
    }
    for (i = 0; i < 6; ++i) {
        c = 'A' + rand() % ('Z' - 'A' + 1);
        printf("%c", c);
    }
    for (i = 0; i < 3; ++i) {
        c = '1' + rand() % ('1' - '9' + 1);
        printf("%c", c);
    }

    printf("\n\n");
    system("pause");
}

#include <stdlib.h>
#include <stdio.h>
#include <time.h>

int main(void) {
    char password[6 + 6 + 3 + 1];
    int i, j=0, len=sizeof(password)-1;

    srand(time(NULL));
    printf("Your Random Password is: ");
    for (i = 0; i < 6; ++i)
        password[j++] = 'a' + rand() % ('z' - 'a' + 1);
    for (i = 0; i < 6; ++i)
        password[j++] = 'A' + rand() % ('Z' - 'A' + 1);
    for (i = 0; i < 3; ++i)
        password[j++] = '1' + rand() % ('1' - '9' + 1);
    password[j] = '\0';
    for(i = 0; i < sizeof(password)-1; ++i)
        {
        char c = password[i];
        j = rand() % len;
        password[i] = password[j];
        password[j] = c;
        }
    printf("%s\n\n", password);
    system("pause");
}

如何在C中混淆输出字符？
