C language implementation for athletes diving rankings

C language implementation for athletes diving rankings
Five athletes participated in the 10-meter diving competition. Some people asked them to predict the results. Contestant A said: B is the first, I am the third. Contestant B said: I am second, E is fourth. Contestant C said: I am the first, and D is the second. Contestant D said: "C, I am the third. Contestant E said: I am the fourth, A is the first. After the competition, each contestant is half right. Please program to determine the ranking of the competition. Code implementation:

#include <stdio.h>int main(){ int a=0,b=0,c=0,d=0,e=0; int flag=0; int ret=0; for(a=1;a<=5;a++) {  for(b=1;b<=5;b++)  {   for(c=1;c<=5;c++)   {    for(d=1;d<=5;d++)    {     for(e=1;e<=5;e++)     {      if((1==(b==1)+(a==3))&&         (1==(b==2)+(e==4))&&         (1==(c==1)+(d==2))&&         (1==(c==5)+(d==3))&&         (1==(e==4)+(a==1)))      {       flag=0;       ret=0;       ret|=(1<<(a-1));       ret|=(1<<(b-1));       ret|=(1<<(c-1));       ret|=(1<<(d-1));       ret|=(1<<(e-1));       while(ret)       {        if(ret%2==0)        {         flag=1;         break;        }        ret/=2;                }       if(flag==0)        {         printf("a=%d b=%d c=%d d=%d e=%d\n",a,b,c,d,e);        }      }     }    }   }  } } return 0;}

 

Result: a = 2 B = 1 c = 1 d = 3 e = 4
