用C语言编写一段程序：删除字符串中的空格，并将原空格后首字母改写为大写字母。

int main(int argc, char* argv[])
{
char str[] = "Whatever with the past has gone, the best is always yet to come.";

char *p = str;
char *p1 = str;
bool is_space = false; //用于标记上一个字符是否为空格

char ch;
while ( (ch = *p++) != '\0')
{
if (ch == ' ') //如果ch为空格
{
is_space = true;
continue; //结束本次循环,进入下一次循环
}

if (is_space) //如果上一个字为空格
{
is_space = false; //清除空格标记
ch = (ch >= 'a' && ch <= 'z' ? ch - 32 : ch); //判断ch是否为小写字母,并将其转换为大写字母
}

*p1++ = ch;
}

*p1 = '\0'; //末尾加结束符

printf("%s\n", str);

return 0;
}
