Question

新手c++错误问题,,,,

程序如下:
#include <iostream.h>

main()
{
char life_insurance[1];
char health[1];
int age=50;
health='B';
if (age<=55 && health=='G')
life_insurance='Y';
if (age<=55 && health=='B')
life_insurance='N';
if (age>55)
life_insurance='N';
cout<<"life insurance issued:"<<life_insurance<<"\n";

}

错误如下:
F:\Microsoft Visual Studio\MyProjects\borland\11.cpp(9) : error C2440: '=' : cannot convert from 'const char' to 'char [1]'

执行 cl.exe 时出错.

11.exe - 1 error(s), 0 warning(s)
有人知道是怎么改错吗,,我怎么也改不过来,

Answer 1

主要是前面定义的问题,char life_insurance[1];
char health[1];
修改成char life_insurance;char health;就对了
main()前加个void

Answer 2

#include <iostream.h>

main()
{
char life_insurance; //同下
char health; //health='B'如果你要这样赋值就不要定义成数组，若要定义成数组就health[0]='B'这样赋值。

int age=50;
health='B';
if (age<=55 && health=='G')
life_insurance='Y';
if (age<=55 && health=='B')
life_insurance='N';
if (age>55)
life_insurance='N';
cout<<"life insurance issued:"<<life_insurance<<"\n";

}
