char *pSource = "This is a English sentence";
char arrSentence[100] = {0};
int i = 0 ,j = 0; //i：源字符串 j：目标字符串
int nSpace = 0;
while ( pSource[i] != 0 )
{
if ( nSpace < 1 ) //允许有一个空格
{
arrSentence[j++] = pSource[i];
}
if ( pSource[i] == ' ' )
{
nSpace ++;
if ( pSource[i+1] != ' ' )
{
nSpace = 0;
}
}
i++;
}
printf("String lenth:%d\n" ,j);
