C++犄角旮旯之结构体数组初始化

#include <iostream>
using namespace std;

struct TK
{
	char * des;
	int i;
};

#define PROJ_HEAD(id) {#id, 1},
//#id 将id换成字符串
int main()
{
	struct TK tks [] ={PROJ_HEAD(eac)
					{0,0}};
	cout << tks[0].des << endl;
	return 0;
}

结果

eac

也可以不使用{}，例子代码如下

struct PJ_ELLPS {
	char	*id;	/* ellipse keyword name */
	char	*major;	/* a= value */
	char	*ell;	/* elliptical parameter */
	char	*name;	/* comments */
};

struct PJ_ELLPS
pj_ellps[] = {
"MERIT",	"a=6378137.0", "rf=298.257", "MERIT 1983",
"SGS85",	"a=6378136.0", "rf=298.257",  "Soviet Geodetic System 85",
"GRS80",	"a=6378137.0", "rf=298.257222101", "GRS 1980(IUGG, 1980)",
0,0,0,0
};
