如何将枚举变量分配给数组索引的指针

Question

Say I have enum unit{ var1, var2, var3}; Then I have an array in the main function

int main (int argc, char *argv[]);

I want to assign argv[1] to var1 , where argv[1] was input through command line, I m not sure how to go about doing this for pointer of array. I know how to get the input from command line but trouble assigning it to var1 .

Answer 1

You can't. Enum values must be known at compile time, but argv is only known at run time.

Answer 2

You cannot change the values of enum at run-time, structs are the best implementation here, I advise you change your code to this;

struct unit{ var1, var2, var3};

Then you can use a pointer to manipulate the values.
