2 回答printf("%d\n%d\n%d\n%d\n%d\n%d\n",++a,--a,a++,a--,a+1,a);

1 回答printf("%d\n",a+1);//为什么不改变值，已经赋值a了啊，+1不是应该101吗

2 回答 printf("x=%d\n",x+1);为什么不会改变x的值呢?求解答谢谢

2 回答char c = 'a'; int n = c ; //将c赋值给n float f = c ; //将c赋值给f double d = c; //将c赋值给d printf("%d\n",n); printf("%f\n",f); printf("%lf\n",d); return 0; }

3 回答#include <stdio.h> int main() { char c = 'a'; int n = 'a'; //将c赋值给n float f = 'a'; //将c赋值给f double d = 'a'; //将c赋值给d printf("%d\n",n); printf("%f\n",f); printf("%lf\n",d); return 0; }
