Question

一道C语言编程题，求大神给个答案！！！！！！

1、请编写函数完成整个程序，要求满足以下main函数的调用。
int main(){
int a[] = {123,145,210,815,44,240,919,310,44,88,123};
int length = sizeof(a)/sizeof(a[0]);
printf("排序前：\n");
print(a,length);
sort(a,length);
printf("排序后：\n");
print(a,length);
return 0;
}

Answer 1

#include<stdio.h>

void sort(int a[],int n)
{
int i,j;
int t;

for(i=0;i<n-1;i++)
{
for(j=0;j<n-i-1;j++)
{
if(a[j]<a[j+1])
{
t=a[j];
a[j]=a[j+1];
a[j+1]=t;
}
}
}
}
void print(int a[],int n)
{
int i;

for(i=0;i<n-1;i++)
printf("%d ",a[i]);
printf("%d\n",a[n-1]);
}

int main()
{
int a[] = {123,145,210,815,44,240,919,310,44,88,123};
int length = sizeof(a)/sizeof(a[0]);

printf("排序前：\n");
print(a,length);
sort(a,length);
printf("排序后：\n");
print(a,length);
return 0;
}
