C++ 未初始化变量，purify检测不到？？？why！

[lulu0126]

 main(){
  	int i=10, j;
    i = j;     /* UMC: j is uninitialized, copied into i */
    printf("i = %d\n", i); /* UMR: Using i, which has junk value */
}

没用过这工具。。。

[herman~~]

没用过
不过vs05以上 变量未初始化好像是有warning，只要你设置了一定的警告级别

[taodm]

purify不是查内存泄漏的嘛。什么时候改行的？

过这工具过这工具

相信人比软件强吧

[lulu0126]

purify

不只能查内存泄漏了！

以下代码

void main(){

	 
  char* p =new char[10];

  std::cout<<p[10]<<std::endl;




}

会报以下信息的，当然这里我要说的不是内存泄漏问题！
[E] ABR: Array bounds read in main {1 occurrence}



呵呵 非常感谢4楼！ 哦！



我要给这个帖子加分怎么加呢！？？？

这些工具多半是忽悠领导们用的。
真正强的是lint, 看看Solaris上lint的输出吧

lint 060.c
(7) warning: variable may be used before set: j

argument unused in function
    (4) argc in main
    (4) argv in main

function returns value which is always ignored
    printf

        printf("i = %d\n", i);  /* UMR: Using i, which has junk value */

        return 0;
