自动类型转换
#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;
}
#include <stdio.h>
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;
}
这样2个做法有区别吗? 结果都是一样的
