将字符串指针赋值给数组[通俗易懂]
2022-07-28 19:45:00 【全栈程序员站长】
大家好,又见面了,我是你们的朋友全栈君。
比如 char *p=”sdflkjasljfsjlsdfsa”; char p1[200]; 将p赋给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) 从存储区 str2 复制 n 个字符到存储区 str1。 (3)用循环也可以: for(int i=0;*(p+i)!=’\0’;i++) { p1[i]=*(p+i); } (4)sprintf(p1,”%s”,p);//p1长度需要大于p,否则会发生溢出 C 库函数 – sprintf() http://www.runoob.com/cprogramming/c-function-sprintf.html linux c之snprintf()和sprintf()区别 https://blog.csdn.net/u011068702/article/details/61916220
