C Pointer is used to allocate memory dynamically i.e. at run time. //定义指针变量的几种形式: //形式1: inta = 10; //定义一个的int型变量a,a赋值为10 int*p; p = &a; //定义一个int型指针变量p,p指向int型变量a并赋值为(be set to the value of)int型变量a的地址,即&a;这一语句表示...
fgets ( demo_arr, 65, fp ); printf("After SEEK_END to -8 \t--->%s\n", demo_arr); //set file pointer to the beginning fseek(fp, 0, SEEK_SET); // use rewind(fp) will do as well fclose(fp); return 0; } 结果 Before using fseek --->WENXUE.ca or 1eq.ca is a laomai...
