看看这两段代码 我用VC++6.0 编译出来都一样???
#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;
}
