Assign a string pointer to an array [easy to understand]

Hello everyone , I meet you again , I'm your friend, Quan Jun .

such as char *p=”sdflkjasljfsjlsdfsa”; char p1[200]; take p Assign to p1 （1）strcpy(p1,p); （2）char *src=”helloworld”; char des[100]={0}; memcpy(des,src,strlen(src)+1); //void *memcpy(void *str1, const void *str2, size_t n) From the storage area str2 Copy n Characters to storage str1. （3） You can also use a cycle : for(int i=0;*(p+i)!=’\0’;i++) { p1[i]=*(p+i); } （4）sprintf(p1,”%s”,p);//p1 The length needs to be greater than p, Otherwise, overflow will occur C Library function – sprintf() http://www.runoob.com/cprogramming/c-function-sprintf.html linux c And snprintf() and sprintf() difference https://blog.csdn.net/u011068702/article/details/61916220
