一个小程序，帮忙简化，谢谢

没看懂程序要表达什么

 for(i=0;i<=23;i++)这个是不是i<=28呢

反正按照你的思路，可以这么优化下
#include<stdio.h>

main()
{
    int t[28]={'a','b','a','b','c','a','b','c','a','c','b','a','b','c','a','c','b','b','a','a','c','c','a','b','c','c','a','a'};
    int p[5]={'a','b','c','a','c'};
    int i,j=0,k=4;
    int flag=0;
    for(i=0;i<=23/2;i++)
    {
        if(j>k){
                printf("t include p\n");
                printf("i=%d\n",i);
                flag=1;
                break;
            }
        if(t[i]==p[j])
        {         
            j++;
        }
        if(t[23-i]==p[k]){
            k--;
        }
    }
    if(flag==0)
        printf("t do not include p/n");
}            

- - 看不懂

不知道，这样是你想要的么，，不过我是用.net写的.
       private static int START_INDEX = 0;

        private void button1_Click(object sender, EventArgs e)
        {
            char[] t={'a','b','a','b','c','a','b','c','a','c','b','a','b','c','a','c','b','b','a','a','c','c','a','b','c','c','a','a'};
            char[] p = { 'a', 'b', 'c', 'a', 'c' };

            int result = 0;
            int total = t.Length -1;
            bool val = false;
            
            Compare(t, p, 0, 0, ref result, ref total);

            if (result == 5)
            {
                val = true;
            }

            MessageBox.Show(val.ToString() + " StartIndex: " + START_INDEX.ToString());
        }

        private void Compare(char[] t, char[] p, int index, int target, ref int result, ref int total)
        {
            if (index == total) return;
            if (result == 5) return;
            

            if (t[index] == p[target])
            {
                if (START_INDEX == 0)
                    START_INDEX = index;
               
                result = result + 1;
                Compare(t, p, index + 1, target + 1, ref result , ref total);
            }
            else
            {
                START_INDEX = 0;
                result = 0;
                Compare(t, p, index + 1, 0, ref result, ref total);
            }
        }

谢谢
