故答案为printf ( " % d " , *pointer1 ) 指针相对于一个内存单元来说,指的是单元的地址,该单元的内容里面存放的是数据。在 C 语言中,允许用指针变量来存放指针,因此,一个指针变量的值就是某个内存单元的地址或称为某内存单元的指针。题目中pointer1是一个指针变量,pointer1=&a表示pointer1指向a的地址。
Each of these functions takes a pointer to an argument list, and then formats and writes the given data to the memory pointed to bybuffer. The versions of these functions with the_lsuffix are identical except that they use the locale parameter passed in instead of the ...
API reference for vsnprintf, _vsnprintf, _vsnprintf_l, _vsnwprintf, and _vsnwprintf_l; which write formatted output using a pointer to a list of arguments.
int a=15;printf("a=%x\n",a); 说明:输出结果是”a=f“,即%x表示以16进制形式输出a所在内存中值,输出长度是sizeof(type_a),其中type_a是指a的类型。 8、printf()、%p输出地址 代码语言:javascript 代码运行次数:0 运行 AI代码解释 int*p;p=(int*)malloc(1234);printf("pointer=%p\n",p);free(...
Writes formatted output to a string. The v...printf functions are known as alternate entry points for the ...printf functions. They behave exactly like their ...printf counterparts, but they accept a pointer to a list of arguments instead of an argument list. vsprintf accepts a pointer to...
Each of these functions takes a pointer to an argument list, then formats the data, and writes up to count characters to the memory pointed to by buffer. If there is room at the end (that is, if the number of characters to write is less than count), the buffer will be null...
