Further, we declare anempty array of type charto store the result i.e. result of the conversion of string to char array. 此外,我们声明了一个char类型的空数组来存储结果,即将字符串转换为char数组的结果。 Finally, we usestrcpy() methodto copy the character sequence generated by the c_str() ...
char string[5]; 然后我们在数组的第一个成员上储存 'H',就是 string[0] = 'H',第二个成员上储存 'E'(string[1] = 'H'),第三个成员上储存 'L'(string[2] = 'L'),第四个成员储存 'L'(string[3] = 'L'),第五个成员储存 'O'(string[4] = 'O'),那么我们就构造了一个字符串。 下图...
A string is nothing but an array of characters. The value of a string is determined by the terminating character. Its value is considered to be 0. As it is evident with the image uploaded above, we need to enter both the strings which we need to concatenate or link. Both the strings ...

char*str = st2.c_str();//almost ok, but not quite c_str 函数返回 C 风格字符串,其字面意思是:“返回 C 风格字符串的表示方法”,即返回指向字符数组首地址的指针,该数组存放了与 string 对象相同的内容,并且以结束符 null 结束。 如果c_str 返回的指针指向 const char 类型的数组,则上述初始化失败...
