我无法为结构中的常量赋值,请遵循以下代码:
#include <iostream>
#include <stdio.h>
typedef struct
{
float a;
float b;
float c;
float intensity;
} PointXYZI;
typedef struct structParent{
int x;
int y;
const PointXYZI* xyzi;
} structParent;
int main()
{
float o = 10.f, p = 5.0f, z = 96.0f;
PointXYZI points = {o, p, z};
const structParent *data = {0,0, &points};
std::cout << " *-* " << data.xyzi->c << std::endl;
std::cout << " *-* " << points.a << std::endl;
return 0;
}
我用以下代码得到以下错误:
错误:标量对象'data'需要初始化程序中的一个元素const structParent * data = {0,0,&points};
谢谢...
@ UnholySheep的答案的示例版本解释如下。
void someFunc(const structParent &x)
// ^^^^^^
{
std::cout << " @_@ " << x.xyzi->c << std::endl;
}
int main()
{
float o = 10.f, p = 5.0f, z = 96.0f;
PointXYZI points = {o, p, z, 0};
// ^^^^^
const structParent data = {0,0, &points};
// ^^^
std::cout << " *-* " << data.xyzi->c << std::endl;
std::cout << " *-* " << points.a << std::endl;
someFunc(data);
// ^^^^^^^
return 0;
}
