参数解析

纯字符串操作，重点在于用0替换空格和‘\”’。
#include"stdio.h"
#include"string.h"
int main(void) {
int i, num = 0, flag = 0;
char str[1002] = {0};
fgets(str, 1001, stdin);
int len = strlen(str);
if (str[len - 1] == '\n') {
str[len - 1] = 0;
len --;
}
for (i = 0; i < len; i++) {
if (str[i] == '\"') {
str[i] = 0;
flag = ~flag;
}
if (str[i] == ' ' && !flag) {
str[i] = 0;
num ++;
}
}
num++;
printf("%d\n", num);
printf("%s\n", str);
for (i = 1; i < len; i++) {
if (str[i] == 0 && str[i + 1]) {
printf("%s\n", &str[i + 1]);
}
}
}
