C++struct结构体的运用-用户信息的一个输入

string的初始化

string str1 = "hello world";      // str1 = "hello world"
string str2("hello world");       // str2 = "hello world"
string str3 = str1;               // str3 = "hello world"
string str4(str2);                // str4 = "hello world"
string str5(10,'h');              // str5 = "hhhhhhhhhh"
string str6 = string(10,'h');     // str6 = "hhhhhhhhhh"
string str7(str1,6);              // str7 = "world"     从字符串str1第6个字符开始到结束，拷贝到str7中
string str8 = string(str1,6);     // str8 = "world"
string str9(str1,0,5);            // str9 = "hello"     从字符串str1第0个字符开始，拷贝5个字符到str9中
string str10 = string(str1,0,5);  // str10 = "hello"
char c[] = "hello world";
string str11(c,5);                // str11 = "hello"    将字符数组c的前5个字符拷贝到str11中
string str12 = string(c,5);       // str12 = "hello"

	string sex;
	float weight;
	float height;
};
int main()

	cin >> name1.name >> name1.sex >> name1.weight >> name1.height;
	cout << name1.name << " " << name1.sex << " " << name1.weight << " " << name1.height;

	return 0;
