C 将文件替换为程序内的字符串

Question

我有一个程序可以从文件 xxx.conf 读取数据配置

FILE *file = fopen("xxx.cof", "rb");

然后数据给出为

char line[128];
while(fgets(line, sizeof(line), file))

我想将文件 xxx.conf 替换为 string file = "name = xxxx\nsurname = xxx\n adress = xxx"

我希望程序从字符串中读取数据。

相反

FILE *file = fopen("xxx.conf", "rb"):

file = "name = xxx\nsurnam =xxx\nadress = xxx"

Answer 1

如果我正确理解你的问题，你应该使用 strtok

  char line[] = "name = xxx\nsurnam =xxx\nadress = xxx";

  char *entry;
  entry = strtok(line, "\n");

  while (entry)
    {
      printf("%s\n", entry);
      entry = strtok(NULL, "\n");
    }

只需将 printf 替换为您的代码
