判斷一段字符串中有多少單詞(以空格爲標準)

直接上代碼

#include <stdio.h> #include <string.h> int wordscount(const char *s) { char *p = (char*)s; int count = 0; while (*p != '/0') { /*去掉空格*/ while (*p == ' ') { ++p; } /*單詞計數*/ if (*p != '/0') { ++count; } /*跳去單詞*/ while (*p != ' ' && *p != '/0') { ++p; } } return count; } int main() { char s[100]; printf("please input the strings:/n"); gets(s); printf("%d/n",wordscount(s)); return 0; }
