Another useful method to initialize achararray is to assign a string value in the declaration statement. The string literal should have fewer characters than the length of the array; otherwise, there will be onl
如果memcpy和memset的参数类型不是void *,而是char *,那才叫真的奇怪了!这样的memcpy和memset明显不是一个 “纯粹的,脱离低级趣味的”函数! 下面的代码执行正确: //示例:memset接受任意类型指针 int intarray[100]; memset ( intarray, 0, 100*sizeof(int) ); //将intarray清0 //示例:memcpy接受任意类型...
voidClearRAM(char array[]){int i;for(i=0;i<sizeof(array)/sizeof(array[0]);i++)//这里用法错误,array实际上是指针{array[i]=0x00;}}intmain(void){char Fle[20];ClearRAM(Fle);//只能清除数组Fle中的前四个元素} 我们知道,对于一个数组array[20],我们使用代码sizeof(array)/sizeof(array[0...

array, the behavior is undefined.C99标准：char *p = "abc"; defines p with type ‘‘pointer to char’’ and initializes it to point to an object with type ‘‘array of char’’ with length 4 whose elements are initialized with a character string literal. If an attempt is made to use...

fmt = va_arg(ap, char *); (void)vfprintf(stderr, fmt, ap); va_end(ap); } Both the va_arg() and va_end() macros work the same for the old-style and ISO C versions. Because va_arg() changes the value of ap, the call to vfprintf() cannot be: (...
