I have a character pointer which points to the character array. I want to clear the character array and then string copy some other array in it.The memset doesn't work on char pointer. Is there some other way around to do that ? int main(){ char a[100] = "coepismycollege"; char...
在C语言中,字符数组和字符指针都是用于处理字符串的重要概念,但它们之间存在一些关键的区别。 字符数组(Character Array) 字符数组是一个可以存储多个字符的连续内存区域。这些字符可以是文本字符串的一部分,或者用于其他目的。字符数组在声明时指定了大小(即可以存储的字符数),并在栈上分配内存。
让我们通过下面的例子,来了解C语言中字符数组和字符指针之间的区别。 voidtest() { //arr is array of characterschar arr[12] = "Aticleworld"; //ptr is pointer to char char *ptr = "Aticleworld"; } 现在,让我们比较arr(字符数组)和ptr(字符指针)。
