While I was trying to do a smash-stacking exploit just like this article:http://www.cs.wright.edu/people/faculty/tkprasad/courses/cs781/alephOne.html, I ran across a problem of needing to convert the stack pointer into a string. I know how to print out an int in a hex format (usin...

这个就出了点变化,则fgets()从流中获取字符到换行符(或eof)为止,例如输入: abcd回车 则string中字符就有五个 a,b,c,d,'\n' 然后才是'\0' ,这就是前面明明输入5个字符,但是strlen()却计算出6个字符的原因。 回到刚开始那个例子,如果按照刚才所说,fgets()在获取少于n-1个字符的情况下 ...
[-Wincompatible-pointer-type]。不知道问题出在哪里 、、 我找不到哪里出了问题。当我运行程序时,它显示“访问被拒绝”。 #include<stdio.h> int main() { char arr[4][40] = { "array of c string", "is fun to use", "make sure to properly", "tell the array size" }; char *p = ar...
const int *p;int * const p;首先说明，这两个定义，定义出的p都是指针！但这两个指针变量定义，又都是定义一个常量，常量是指的哪个？Bjarne在他的The C++ Programming Language 里面给出过一个助记的方法：把一个声明从右向左读，* 读成 pointer to：const char * p;p is a pointer to ...
