个人建议不要将输入的数值赋给int类型，你是无法判断输入的到底是不是字母，可以通过%s赋给char数组，char a[10];scanf("%s",a);然后逐位的判断有没有字母 for(i=0;a[i];i++){ if((a[i]>'9')||(a[i]<'0'))...else ...} 如果没有字母就可以通过字符串转数字的函数将其转化为...
B. an odd integerC. divisible by 8D. a multiple of 2nE. a positive integer 相关知识点: 试题来源: 解析C 若n是奇数,则n2-1: (A) 质数 (B) 奇数 (C) 能被8整除 (D) 2n的倍数 (E) 正整数 因为n是奇数,所以n可以表达成n=2k+1,k是整数。由此可得: n2-1=(n+1)(n-1)=(2k+2...
