c++ error logs

启用-Wall
帮忙解决太多bug.

alias g++='g++ -Wall'

1	alias g++='g++ -Wall'

写入配置文件

echo "alias g++='g++ -Wall'" >> ~/.bashrc && source ~/.bashrc

1	echo "alias g++='g++ -Wall'" >> ~/.bashrc && source ~/.bashrc

以下代码皆为错误代码

括号,万恶的括号！
accept 返回值是0

if ((fd = accept(Sockfd, Addr, (socklen_t*) AddrLen) < 0)) {
}

1 2	if ((fd = accept(Sockfd, Addr, (socklen_t*) AddrLen) < 0)) { }

函数没有返回值！
string产生的Segmentation fault

string testString(string &a){
    a = "I'm string";
}

string testString(string &a){

a = "I'm string";

}

循环
栈溢出

char *lists[maxToken];
lists[0] = strtok(buffer, white);
int i = 1;
while ((lists[i] = strtok(NULL, white)) != NULL && i < maxToken) {
    i++;
}

char *lists[maxToken];

lists[0] = strtok(buffer, white);

int i = 1;

while ((lists[i] = strtok(NULL, white)) != NULL && i < maxToken) {

i++;

}
