[CodeEngn] Reverse L14 Start

Reverse L14 Start

ID가 CodeEngn일때 PW를 구해라.(다만여러가지의답이있으니 숫자 5자리로한다) (Brute Force)

#include<stdio.h>
#include<Windows.h>

int main(){
char s[6]="10";
char s2[6];
int i=0;
int sint=0;
int sum=0;
int j;
int k=10000;
//revers codeengn 14
//76193 0x129a1==CodeEngn

while(k<99999){
itoa(k,s,10);

 i=0;
 sint=0;
 sum=0;

for(i=0;i<5;i++){
s2[i]=s[i]-48;
sint=s2[i];

for(j=4-i;j>0;j--){
sint*=10;
}

sum+=sint;
}

if(sum==0x129a1){
printf("######################\t\t");
printf("Congration!! Key is %s",s);
printf("\t######################\n\n");
break;
}
k++;
}

}

  

0x129a1은 CodeEngn일때맞춰줘야하길래.. 10000 ~ 99999까지 무작정대입.
