1—n之间所有数的平方和与立方和

#include <stdio.h>int main(){   int i,n;   int sum=0,cot=0,term;   printf ("please enter a value what you want：");   scanf ("%d",&n);   for (i=1;i<=n;i++)   {   term=i*i;   sum+=term;   }    printf ("平方和sum=%d\n",sum);   for (i=1;i<=n;i++)   {   term=i*i*i;   cot+=term;   }   printf ("立方和cot=%d\n",cot);    return 0;}
