#include
int main() { 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; } //没错啊 怎么不能运行呢#include后面缺少头文件<stdio.h>
完全运行得了的
#include <stdio.h> int main() { char c='a'; int n=c; float f=c; double d=c; printf("%d\n",n); printf("%f\n",f); printf("%f\n",d); return 0; }
