int main(){

int i,a[50],b[50],sum=0,count = 0;

浮动平均值;

Printf("随机生成50个两位正整数:\ n ");

srand((无符号)时间(空));

for(I = 0;我& lt50;i++){

a[I]= rand()% 90+10;

sum = sum+a[I];

if((i+1)%10==0)

printf("%d\n ",a[I]);

其他

printf("%d ",a[I]);

}

平均值=(浮点)总和/50;

Printf("高于平均值元素:\ n ");

for(I = 0;我& lt50;i++){

if(a[I]& gt;平均){

count++;

if(count%10==0)

printf("%d\n ",a[I]);

其他

printf("%d ",a[I]);

}

}

printf(" \ n数字为5的元素:\ n ");

count = 0;

for(I = 0;我& lt50;i++){

if(a[I]/10 = = 5 | | a[I]% 10 = = 5){

b[计数]= a[I];

count++;

}

for(I = 0;我& lt数数;i++){

if(b[i]%10==0)

printf("%d\n ",b[I]);

其他

printf("%d ",b[I]);

}

返回0;
