Question

我在做一道简单的初学编程题目，是求n1~n2的累加和，可是出现了一个错误，求高手指点，谢谢

程序：
int Suml(int n1,n2)
{
int i,sum;
sum=0;
for(i=n1;i<=n2;i=i+1)
sum=sum+i;
return sum;
}
#include<stdio.h>
void main(void)
{
int n1,n2,sum;
printf("请输入数值n1:");
scanf ("%d",&n1);
printf("请输入数值n2:");
scanf ("%d",&n2);
sum=Suml(n1,n2);
printf("n1—n2的累加和为%d",sum);
}

错误：C:\Documents and Settings\Administrator\桌面\Text4.c(1) : error C2081: 'n2' : name in formal parameter list illegal
Error executing cl.exe.

Answer 1

#include<stdio.h>
int Suml(int n1,int n2) //这里
{
int i,sum;
sum=0;
for(i=n1;i<=n2;i=i+1)
sum=sum+i;
return sum;
}

void main(void)
{
int n1,n2,sum;
printf("请输入数值n1:");
scanf ("%d",&n1);
printf("请输入数值n2:");
scanf ("%d",&n2);
sum=Suml(n1,n2);
printf("n1—n2的累加和为%d",sum);
}

Answer 2

开头就错了
应该是int Suml(int n1,int n2)
n2前面没定义

Answer 3

n2公式中没定义

Answer 4

一楼正解......
