【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=0;
    int i=0;
    int count=0;
    while(s[i])
    {
        if(!flag&&!(s[i]==' '||s[i]=='\t'))
        {
            flag=1;
            count++;
        }
        else
        if(flag&&(s[i]==' '||s[i]=='\t'))
            flag=0;
        i++;
    }
    return count;
}
