【LeetCode】434. Number of Segments in a String

Count the number of segments in a string, where a segment is defined to be a contiguous sequence of non-space characters.

Please note that the string does not contain any non-printable characters.

Example:

Input: "Hello, my name is John"
Output: 5

找出连续字符串个数（注意示例中Hello,后面有空格）
解题思路：
　　设立标志位，遍历字符串，当标志位从0变为1时，count++

 int countSegments(char* s) {
     int flag=;
     int i=;
     int count=;
     while(s[i])
     {
         if(!flag&&!(s[i]==' '||s[i]=='\t'))
         {
             flag=;
             count++;
         }
         else
         if(flag&&(s[i]==' '||s[i]=='\t'))
             flag=;
         i++;
     }
     return count;
 }
