用c语言编写求输入20个数的平均值

for(i=0;i<20;i++)avg = avg + a[i];avg = avg/20.00;printf("The average of those number is:%f",avg);}

average = sum/20;printf("这20个数的算术平均值是:%f\n",average);}

您好！完整代码如下：include <stdio.h> include <math.h> void main( ){ float a[20],pjz=0,s,t;int i,k;for(i=0;i<20;i++) scanf("%f",&a[i]);for(i=0;i<20;i++) pjz+=a[i];pjz/=20 ;s=fabs(a[0]-pjz);t=a[0] ;for(i=1;i<20;i++)if(fabs(a[i]...

include<stdio.h> void main(){ int a[20],n,j;printf("输入20个整数:")for(i=0;i<20;i++){ scanf("%d",&a[i]);} //求平均数 n=0;for(i=0;i<20;i++){ n+=a[i];} printf("平均数是:%d\n",n/20);//找出质数并显示 printf("其中质数是:");n=0;for(i=0;i<...

给你写了，你看看吧 include <stdio.h> int main(void){ int a[20], i, j, sum =0, temp;for(i =0; i <20; i++){ printf("请输入第%d个数字：", i);scanf("%d",&a[i]);sum += a[i];} printf("平均值：%f\n",(float)sum /20);for(i =0; i <19; i++)for(...

float student [20],total=0,average;for(int i=0;i<20;i++){scanf("%f",&student[i]) ;total+=student[i];} average=total/20;printf("%f",average);

1.定义个数组，将20个整数放入其中,int 型的max ,min， sum，float 型的mean；2.设定max=a[0],min=a[0],mean=0.0,sum=0；3.for语句遍历整个数组a，比较各个数与max ，min 的大小关系，依据结果重新设置max ,min的值，并且将数组中各值相加（sum）；4.输出max ,min ,mean(=sum/20)。

min_func(int a[],int n){int i,min;for(min=a[0],i=1;i<N;i++) //初始默认最小值为a[0],遍历数组元素if(min>a[i]) //如果当前最小值>当前数组元素，则将该元素赋值给minmin=a[i];return min;}//求和函数int sum_func(int a[],int n){int i,sum;...

0;int count = 0;for(i=0;i<20;++i){printf("please input 20 numbers:");scanf("%d",&a[i]);}for(i=0;i<20;++i){count += a[i];}avi = count/20;for(i=0;i<20;++i){printf("%d 和平均值%d的绝对值为：%d\n",a[i],avi,abs(avi - c[i]));}return 0;} ...

include <stdio.h>int main(void){int a[20];int i=0;for (;i<20;i++)scanf("%d",&a[i]);int result=0;for (i=0;i<20;i++)result+=a[i];printf("和为:%d\n平均值为:%f\n",result,result/20.0);/*20.0不能改为20*/result=a[0]for (i=1;i<20;i++){if (...
