[英]Function 'strlen' could not be resolved - Eclipse cpp
I'm new on Ecplipse for cpp, i'm having a lot of problem. 我是Cpp的Ecplipse的新手,我遇到了很多问题。
FIXED: 1) on the begining there was no INCLUDING FOLDER by dafault. 已修正:1)开始时,dafault没有包含文件夹。
Unpached the Eclipse's zip but it was with no libriries (or including) so i set the "Path and symbols" with the inclusing folder's DEV ( installed MinGW and included their too). 取消了Eclipse的zip的补丁,但是没有任何库(或包含库),因此我使用包含文件夹的DEV(安装了MinGW,也包括它们)设置了“路径和符号”。 Doing that, i fixed the problem of including.
这样做,我解决了包含的问题。
NOT FIXED: 2) "Function 'strlen' could not be resolved" 未修正:2)“函数'strlen'无法解析”
NOT FIXED 3) "Program "g++"(gcc too) not found in PATH" 不固定3)“在路径中找不到程序” g ++“(也为gcc)
I set the PATH with the bin of: dev, mingw and mingw/msys folders... but didn't work 我使用以下文件夹将PATH设置为:dev,mingw和mingw / msys文件夹...但是没有用
#include <iostream>
#include <stdlib.h>

hoping the code isn't the problem. 希望代码不是问题。

For Problrem 2: 对于Problrem 2:
To use functions like strcpy, strlen, etc you must include string header file. 要使用strcpy,strlen等功能,必须包含字符串头文件。
#include<string.h>
or 要么
#include<cstring>
For Problem 3: 对于问题3:
