找出最大和第二大值 #include 
     
      #include 
      
       #include 
       
        int main(){    int mynum[] = {
    43, 88, 56, 24, 78, 12, 8,29,57,80};    int max=0;    printf("%d\n", max);    int smax=0;    printf("%d\n", smax);    if (mynum[0] > mynum[1])    {        max = mynum[0];        smax = mynum[1];    }    else    {        max = mynum[1];        smax = mynum[0];    }    for (int i = 2; i < 10; i++)    {        if (max < mynum[i])        {            smax = max;            max = mynum[i];        }        else if ((mynum[i]
        
         smax))        {                    smax = mynum[i];        }    }    printf("%d\n",max);    printf("%d\n", smax);    system("pause");}

数组的逆序----思想是第一个和最后一个，第二个和倒数第二个

#include 
     
      #include 
      
       #include 
       
        int main(){    int mynum[] = { 43, 88, 56, 24, 78, 12, 8, 29, 57, 80 };    int cnt = sizeof(mynum) / 4;    printf("%d\n",cnt);    for (int i = 0; i < cnt/2; i++)    {        int temp = mynum[i];        mynum[i] = mynum[cnt - i - 1];        mynum[cnt - i - 1] = temp;    }    for (int i = 0; i < 10; i++)    {        printf("%d,", mynum[i]);    }    system("pause");    return EXIT_SUCCESS;}

字符串逆序，------目前只能应用于中间带空格的英文字符串

#include 
     
      #include 
      
       #include 
       
        int main(){    char mywords[] = "hello world";    int cnt;    cnt = sizeof(mywords)-1;    printf("%d\n",cnt);    for (int i = 0; i < cnt/2; i++)    {        if (i == 6)        {        }        else        {            char temp = mywords[i];            mywords[i] = mywords[cnt - i - 1];            mywords[cnt - i - 1] = temp;        }            }    for (int i = 0; i < sizeof(mywords); i++)    {        printf("%c", mywords[i]);    }    system("pause");    return EXIT_SUCCESS;}
