[英]Pointer and Character
My code is suposed to get the separated numbers, the thing is I have already seen numerous tutorials and I do not understand why it runs when I set: 我的代码是用来获取分开的数字,事情是我已经看过很多教程,我不明白为什么它在我设置时运行:
p = "123 23 32"
out>>
123
23
32
0
0
But when I set it equals to character array It only finds the first number, event though I "walk" in to the p
pointer: 但是当我设置它等于字符数组它只找到第一个数字,事件虽然我“走”到
p
指针:
#include<stdio.h>
int main()
{
int N, i=0, NUMERO = 1, FINAL = 0;
char ORDEM[100000], *p = ORDEM;
scanf("%s", ORDEM);
p = ORDEM;
for(i = 0; i<5; i = i + 1)
{
printf("%d\n", atoi(p));
while (*p != ' ') p++;
if (*p == ' ') p++;
if (*p == '\0') break;
}
return 0;
}
scanf("%s", ORDEM);
scanf()
delimits by space characters. scanf()
按空格字符分隔。 Thus ORDEM
contains only "123"
in your test case. 因此,
ORDEM
在您的测试用例中仅包含"123"
。
To read the whole line, you should call fgets()
. 要读取整行,您应该调用
fgets()
。
fgets(ORDEM, 100000, stdin);
