//gcc编译通过

//g++编译失败如下
example.c: In function ‘int main()’:
example.c:13: error: invalid conversion from ‘void*’ to ‘void* (*)(void*)’
example.c:13: error: initializing argument 3 of ‘int pthread_create(pthread_t*, const pthread_attr_t*, void* (*)(void*), void*)’
要使g++编译通过,方法如下:
C++禁止将void指针随意赋值给其他指针。
因此你在把void thread(void)函数的入口转换为void*,然后当作参数调用pthread_create时就出现错误,因为pthread_create的参数里应该是指向形如void* fun(void*)函数的一个指针。
可以修改void thread(void)为void* thread(void*),然后去掉调用时的(void*)强制转换,错误消除。
二、C语言getchar问题
getchar()输入字符是,需要对回车键进行存储,否则将会在下次一调用getchar()时存储!
