Question

求C语言编程计算，1+(1+2)+(1+2+3)+(1+2+3+4)+…+(1+2+3+…+9+10)的和

Answer 1

#include "stdio.h"
#define N 10
void main()
{
int i,j,sum=0,SUM=0;
for(i=1;i<N+1;i++)
{
for(j=1;j<i+1;j++)
{
sum+=j;
}
SUM+=sum;
sum=0;
}
printf("SUM=%d",SUM);
}

Answer 2

Private Sub Form_Click()
s = 0
For b = 1 To 20
a = 1
For x = 1 To 20
a = a * x
Next x
s = s + a
Next b
Print s
End Sub

Answer 3

#include<stdio.h>
void main()
{
int i,t=0,sum=0;
for(i=1;i<=10;i++)
{
t=t+i;
sum=sum+t;
}
printf("sum=%d\n",sum);
}
