为什么运行结婚是097

Question

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

Answer 1

#include <stdio.h> 

int main() { 

char c = 'a';   // a 的ACSII码是97 

int n = c; //将c赋值给n    这时n的值是97 

float f = n; //将c赋值给f  

double d = f ; //将c赋值给d 

printf("%d\n",n); 

printf("%f\n",f);  

printf("%lf\n",d); 

return 0; 

}

有什么不会的再问我。
