#include <iostream>#include <assert.h>using namespace std;//串连字符串char *strcat1(char *strDest, const char *strSrc){assert(strDest != NULL && strSrc != NULL); //断言保证传进来的参数不是空char *address = strDest;while (*strDest != '\0'){++strDest;}while ( (*strDest++ = *strSrc++)!= '\0');return address;}int main(void){ char s[20] = "hello world";//开辟多一点空间，不如塞不下t啊char *t = "hello";cout<<sizeof(s)<<endl;cout<<strlen(s)<<endl;cout<<strcat1(s,t)<<endl;cout<<sizeof(s)<<endl;cout<<strlen(s)<<endl; system("pause"); return 0;}
