#include<iostream>
using namespace std;

int main()
{
	char str[] = "2232344434";

	for (int i = 0; i < strlen(str); i++)
	{
		printf("%c", *(str+i));
	}

	const char* arr = "12343545";
	for (int i = 0; i < strlen(arr); i++)
	{
		printf("%c", *(arr + i));
	}

	char str[] = {'1','2','3','4','\0'};

	for (int i = 0; i < strlen(str); i++)
	{
		printf("%c", *(str+i));
	}

}

前两个字符串常量都不可以改变
