1.设计函数 int atoi(char *s)。
int atoi(char *s)
{
char sign;
char sign_val = 1;
int val = 0;
int n = 0;
/* skip spaces */
while (isspace(*s))
++s;
if (*s == ~-~ || *s == ~+~)
/* skip ~-~ and ~+~ sign */
{
sign = *s;
if (sign == ~-~)
sign_val = -1;
++s;
}
/* when goes here, it is not space or sign */
while ((*s != ~\0~) && isdigit(*s))
{
val = 10 * n + (*s - ~0~);
n = val;
s++;
}
if (*s != ~\0~)
{
printf("non digit in your input!!\n");
exit(-1);
}
/* non error occured */
return (sign_val * val);
}
