C语言冒泡排序法出现Debug/实验7-8.exe : fatal error LNK1120: 1 unresolved externals错误 怎么办?

#include
void input(int a[],int N)
{
int i;
printf("请输入%d个数: \n",N);
for(i=0;i }
void output(int a[])
{
int i;
printf("排序后: ");
for(i=0;i printf("\n");
}
void bub_sort(int a[],int N)
{
int i,j,temp;
for(i=0;i for(j=0;j if(a[j]>a[j+1])
{temp=a[j]; a[j]=a[j+1]; a[j+1]=temp;}
}
void main()
{
int a[10];
input(a,10);
otput(a,10);
}

看了一下你的代码,没有包含头文件

 #include <stdio.h>

,而且下面的代码有语法错误,for循环的用法错误.

#include<stdio.h>    
void input(int a[],int N)
{
    int i;
    printf("请输入%d个数: \n",N);
    for(i=0;i<10;i++) 
        {
            scanf("%d",&a[i]);
        }   
}         
void output(int a[],int N)
{
    int i;
    printf("排序后: \n");
    for(i=0;i<N;i++)
        printf("%d\t",a[i]);
}
void bub_sort(int a[],int N)
{
    int i,j,temp;
    for(i=0;i<N;i++)
    {
        for(j=N-1;j>i;j--)
        {
            if(a[j]>a[i])
            {
                a[j]=a[j]+a[i];
                a[i]=a[j]-a[i];
                a[j]=a[j]-a[i];
            }
        }
    }

}
void main()
{
    int a[10];
    input(a,10);  //输入 
    bub_sort(a,10);  //排序 
    output(a,10);  //输出 
}
