[問題] 一個非常簡單的問題...
小弟今天初上C++的課程
老師上課寫了個題目,直接在課堂上請大家練習寫看看
過程與題目程式碼都看過了
所以我也試著想一下,寫了如下的過程,結果complie時出現2error
自認無問題,快下課時,請老師看一下,老師也覺得沒問題
但是就是一直error =.=
#include <stdio.h>
void main(void)
{
int i,N,sum;
sum = 0;
printf("input a number:");
scanf("%d",&N);
for (i=1,i<=N,i++)
{
sum=sum+i;
}
printf("1+2+3+..+%d=%d \n",N,sum);
}
請好心的版友幫幫忙...>_<
