After a project has been running for a long time, I find that my code implementation capabilities are getting worse and worse! After looking for a job some time ago, You can obviously feel that your code is not mature enough! Therefore, more exercises are required in the future. If you want to be a good programmer, you have to think more about code.

★Conclusion

The stack concept is used to compress the remainder obtained by integer N and R, and then compress the remainder obtained by N/R to the stack until n/R is less than R. You can use arrays to simulate stack operations. You can store the remainder into an array and then output it in reverse order!

★Code Implementation

#include <stdio.h>int main(){    int a,b,c,n,r,i,flag,len;    char s[100];    while(scanf("%d %d",&n,&r)!=EOF)    {        if(n >= 0)                              {            b = n;            i = 0;            while(b > r)            {                a = b;                s[i++] = a%r;                b /= r;                     }                         s[i] = b;             flag = i;        }                 else        {            b = -n;            i = 0;            while(b > r)            {                a = b;                s[i++] = a%r;                b /= r;                         }            s[i++] =b;            s[i] = '-';            flag = i;        }                        for(i = flag;i >=0;i --)        {            if(s[i]=='-')            {                printf("%c",s[i]);                  continue;               }            if(s[i]==10)               printf("A");            else if(s[i]==11)               printf("B");            else if(s[i]==12)               printf("C");            else if(s[i]==13)               printf("D");            else if(s[i]==14)               printf("E");            else if(s[i]==15)               printf("F");               else               printf("%d",s[i]);                            }                    printf("\n");               }    return 0;    }
