如何为多个执行存储变量值

Harish Hi,How to store a variable value for more than one executions. Ex: main(){int i=0;i++;printf("%d",i);} For first execution output should be 1For Second execution output should be 2 nth exection output should be n Any help is appreciated Thnaks in AdvanceHarish 推荐答案 ha ****** @ gmail.com 写道： ha******@gmail.com wrote: 如何为多个执行存储变量值。 不止一次执行？如果不诉诸外部 存储空间是不可能的，唯一的标准类型是文件。 main（） { int i = 0; i ++; printf（"％d"，i）; } 对于第一次执行输出应为1 第二次执行输出应该是2 How to store a variable value for more than one executions.More than one execution? Can''t be done without resorting to externalstorage, the only Standard kind of which are files. main() { int i=0; i++; printf("%d",i); } For first execution output should be 1 For Second execution output should be 2 像这样，你不能这样做。你需要在程序结束时将i的值写入 文件，然后在你下次执行 时再读回来。没有像静态但更大的关键字，如果那是' 你想要的东西。 Richard Like this, you can''t do that. You''ll need to write the value of i to afile at the end of the program, and then read it back when you start thenext execution. There is no keyword like "static-but-larger", if that''swhat you were looking for.
