第二题：[mw_shl_code=c,true]#include <stdio.h>
int main(void){
double high = 100;//The atitude the ball is
double rebound = 0;//total rebound
int i;//counter
for (i = 0; i <=10; i++){
rebound += 1.5*high;
high *= 0.5;
}
printf("The total distance the ball went is %lf, it rebounds at 10 times %lf",rebound,high);
return 0;
}

第六题 //不知道怎么优化空间，反正就按实现功能写了一下
[mw_shl_code=c,true]#include <stdio.h>
#define MAX 20
//prototypes
charswap(char str, int length);//a function that exchange the first elemrnt and the last
char* printout(char* str, int length);//printf the chars in array ^_^!
charswap (charstr, int length){
char temp = 0;
char* first = str;
char* last = str+length-1;
while (last > first){
temp = *first;
*first = *last;
*last = temp;
first ++;

}
return str;
}
char* printout(char*str, int length){
int i = 0;//counter
for (i = 0; i<length; i++){
printf("%c",str[i]);
}
printf("\n");
}
int main(void){

printf("The original string is: ");

printf("The string has been swaped is: ");
