那这个20是什么意思呀???
而且,:
#include <stdio.h>
#include <string.h>
#define DENSITY 62.4
int main()
{
float weight, volume;
int size, letters;
char name[40];
printf("Hi!What`s your first name?\n");
scanf_s("%s", name,20);
printf("%s,what`s your weight in pounds.\n", name);
scanf_s("%f", &weight);
size = sizeof name;
letters = strlen(name);
volume = weight / DENSITY;
printf("Well,%s,you volume is %2.2f cubic feet.\n", name, volume);
printf("Also,your first name has %d letters,\n", letters);
printf("and we have %d bytes to store it.\n", size);
return 0;
}
我已经加上了,但是还是不行,不知道为什么? |
