C语言编程 ：一维数组a中有10个整数，编写程序，输出这组数的整数和及正数的平均值

Answer 1

给你一份C++的，C的已经有人给了

#include<iostream>

using namespace std;

int n=1000;

double *a=new double[n];

double *b=new double[n];

void sort(double a[])

{

int sum=0;int j=0;

for (int i=0;i<n;i++)

{

if (a[i]>0)

{

b[j]=a[i];

sum=sum+b[j];

j++;

}

}

cout<<"The count of positive digits is:"<<j<<"\n";

sum=sum/j;

cout<<"The average of positive digits is:";

cout<<sum<<"\n";

cout<<"The positive digits is:"<<"\n";

for (int i=0;i<j;i++)

{

cout<<b[i]<<"\n";

}

}

int main()

{

cout<<"Input the size of digits：";

cin>>n;

cout<<"\n";

cout<<"Input the digits：";

for (int i=0;i<n;i++) 

{

cin>>a[i];

}

sort(a);

return 0;

}

Answer 2

#include
int main()
{
int i;
float avg=0.0,a[10];
for(i=0;i<10;i++)
{
scanf("%f",&a[i]);
avg+=a[i];
}
printf("%.2f",avg/10);
return 0;
}
/*
运行结果：
1 2 3 4 5 6 7 8 9 0
4.50
*/

追问

是整数和及平均值
