[C++]간단한 strlen, strcmp, strcat, strcpy, strtok

strlen, strcmp, strcat, strcpy, strtok 사용하는 것에 대해

간단히 적어둔 코드입니다.

	#include <iostream>
	using namespace std;
	int main()
	{
	//str함수
	//1. strlen
	char str[10] = "123456789";
	cout << str << endl;
	cout << strlen(str) << endl;
	//2. strcmp
	char str2[10] = "ab";
	char str3[10] = "ac";
	int num2 = strcmp(str2, str3);
	cout << num2 << endl;
	//3. strcat
	char str4[20] = "동물의 왕국";
	char str5[10] = ".avi";
	cout << strcat_s(str4, str5) << endl;
	//4. strcpy
	char str6[20] = "";
	char str7[20] = "동물의 왕국.avi";
	cout << strcpy_s(str6, str7) << endl;
	//5. strtok
	char str8[1024] = "언니 저 마음에 안 들죠?";
	char *p = NULL;
	char *pp = NULL;
	int count = 0;
	p = strtok_s(str8, " ", &pp);
	//p = strtok(str8, " ");
	for (count = 0; p != NULL; count++) {
	cout << p << endl;
	p = strtok_s(NULL, " ", &pp);
	//p = strtok(NULL, " ");
	}
	cout << "token : " << count << endl;
	return 0;
	}
