请看一段简单程序
关于(if(p)*p=0;)//请教：
& if(p)*p=0; &
& 怎么理解？ &
//p & 可作为逻辑表达式？
int & ReadDat(void)
& FILE & *
& int & i=0;
& char & *p;
& if((fp=fopen( &IN.DAT &, &r &))==NULL) & return & 1;
& while(fegts(xx[i],80,fp)!=NULL)
& p=strchar(xx[i], '\n ');
& if(p)*p=0;
& maxline=i;
& fclose(fp);
& return & 0;
p 可作为逻辑表达式？
================
if(p)等价与if(p != NULL)
LJYVFP & &
& & （0）（0）strchr(不是strchar）返回的是指针（char *），即指向串中 &\n &的位置，
if (p) *p=0;
就是说将串中的第一个 &\n &替换为 &\0 &。
的含义为：指针p不是空指针则条件成立，p为空置针则条件不成立。
不一定非得是严格的逻辑表达式，编译器将隐式地转换为逻辑表达式，
比如上面的
if (p != NULL)。
ljypetrel & &
& & （0）（0）if(可以是变量)
如果是指针的话 意思是 if(p != NULL)
如果是int类型 if(a) 则 a& 0为真
ljytianwen & &
& & （0）（0）to: luya123()
如果是int类型 if(a) 则 a& 0为真
不对，应该是 if(a) 相当于 if( a != 0 )
ljynet & &
& & （0）（0）逻辑有错误，应该是：
swordyu & &
& & （0）（0）(if(p)*p=0;)
if(p) 等价于 if(p=!0)
对于指针，也等价于if(p=!NULL)
swordsword207 & &
& & （0）（0）while(fegts(xx[i],80,fp)!=NULL)
p=strchar(xx[i], '\n ');
if(p)*p=0;
strchar 是自定义的函数么？
似乎这样可能也是对的 ～
看楼主自己需要什么样的结果吧～sworld & &
