使用数学来增加体重值

#include <stdio.h>
#include <stdlib.h>
int main()
{
   char weight[4];
   int w;
   printf(Enter your weight:);
   gets_s(weight);
   w=atoi(weight);
   printf(Here is what you weigh Now: %d\n,w);
   w=w+1;
   printf(Your weight after the potatoes: %d\n,w);
   w=w+1;
   printf(Here you are after the mutton: %d\n,w);
   w=w+8;
   printf(And your weight after dessert: %d pounds!\n,w);
   return(0);
}
