我想转换日期格式" Www Mmm dd hh:mm:ss yyyy",并且只复制" dd hh:mm:ss"用c ++中的字符串。
到目前为止,我一直在努力:
char str[255];
char str1[255];
int y = 0;
int i;
time_t timer;
timer = GetTickCount();
strcpy(str, ctime(&timer));
sendBuff[strlen(str) - 1] = '\0'; //to remove the new-line from the created string
//to copy from the string the exact Time Without Date from the struct of Www Mmm dd hh:mm:ss yyyy - will take only hh:mm:ss
for (i = 11; i < 19; i++, y++)
strcpy(&str1[y], &str[i]);
答案 0 :(得分:0)
代码将如下所示,如Joachim使用substr
所建议的那样std::string temp = str.substr(11, 9); //from 11the place copy next 9 characters
strcpy(str1, temp.c_str());
