1 回答printf("%f\n",f);與printf("%lf\n",d); 的區(qū)別

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

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