如何输入多组数据

发布时间:2022-02-07 12:17:18

⑴ 怎么实现多组数据的同时输入和输出

定义一个数组变量用来读入,例如a[]
i=0;
a[0]=0;
while(a<>-1)do begin
i=i+1;
read(a[i]);
end;
如此输入数据,输出也是,用一个数组来存放输出数据并依次按格式输出

⑵ C++怎么输入多组数据

C++中实现多组数据输入主要有两种方式:

1.首先输入一个n,表示将有n个输入输出,例如:

#include<iostream>
usingnamespacestd;
intmain()
{
intn,a;
cin>>n;
while(n--){
cin>>a;
cout<<"输出:"<<a<<endl;
}
return0;
}
/*
运行结果:
3
111
输出:111
222
输出:222
333
输出:333
*/

2.使用while(cin>>a){}语句,直达输入ctrl+z,结束输入,例如:

#include<iostream>
#include<stdio.h>
usingnamespacestd;
intmain()
{
inta;
while(cin>>a){
cout<<"输出:"<<a<<endl;
}
return0;
}
/*
运行结果:
5
输出:5
6
输出:6
8
输出:8
^Z
*/

⑶ matlab 怎么输入多组数据

n=input('输入数字个数');
for ii=1:n
x(ii)=input('输入数字:');
end
mean(x)

⑷ C语言如何实现输入多组数据测试

循环按照格式读入每组数据即可。

对于输入多组数据测试的情况,需要约定结束的类型,常用的有两种:

1 当读入数据为一组特定值时,结束测试。

比如每组2个整型数据,以空格分隔,当输入的两个数均为-1时,结束测试。代码可以写作:

inta,b;
while(1)
{
scanf("%d%d",&a,&b);
if(a==-1&&b==-1)break;//退出测试的条件。
//测试代码。
}

2 当读到EOF时,结束测试。

同样读入两个整型数据,以空格分隔,当读到EOF时结束测试。代码可以写作:

inta,b;
while(scanf("%d%d",&a,&b)!=EOF)//当出现EOF时,结束测试。
{
//测试代码。
}

⑸ 怎么实现多组数据输入。格式要求如图

其实OnlineJudge上的多组数据输入和我们平时要求的多组数据输入是一样的
就是处理好第一组数据之后能再处理下一组输入
而不是将数据一次性全部输入
如果有case的数量就用它来计数,主要处理操作用放在循环里
如果没有的话就用scanf()的返回值
如:while(scanf("%d%d",&a,&b)==2)
{
...
}

⑹ ACM里说多组数据怎么输入啊

int n,sum=0;
while(scanf("%d",&n)!=EOF)
{
sum+=n;
}
EOF 处理到文件的结束就可以了。
根据题目的要求在合适的位置输出就可以了,如果每组数据都要输出,则写在循环里面,如果所有数据加完了在输出,那么就在循环外边。
只要你知道是要处理到文件结束就根据题目的要求做就可以了。
如果sum是求所有的输入的和,就是放在外边的!请楼上的兄弟认真思考后再发言。

⑺ 想问一下怎么输入多组数据啊,就是需要输入多组二维数组

inta[5][5];
inti,j,N;

scanf("%d",&N);
while(N--)
{
for(i=0;i<5;i++)
for(j=0;j<5;j++)
scanf("%d",&a[i][j]);
//以上就完成了数组的读入
//自己补充,查找最大数和四个最小数吧
//以下完成输出
for(i=0;i<5;i++)
{
for(j=0;j<5;j++)
printf("%d",a[i][j]);
printf(" ");
}
printf(" ");
}

⑻ C语言中如何实现多组数据输入输出

仔细认真看看下面的会对你有帮助的,嘿嘿

输入格式:有多个case输入,直到文件结束
输出格式:一行一个结果
Problem Description
Your task is to Calculate a + b.
Too easy?! Of course! I specially designed the problem for acm beginners.
You must have found that some problems have the same titles with this one, yes, all these problems were designed for the same aim.

Input
The input will consist of a series of pairs of integers a and b, separated by a space, one pair of integers per line.

Output
For each pair of input integers a and b you should output the sum of a and b in one line, and with one line of output for each line in input.

Sample Input
1 5
10 20

Sample Output
6
30

}
return 0;
}

scanf("%d",&n);
}
while (n--)
{
scanf("%d%d",&a,&b);
printf("%d\n",a+b);
}
}

//*************************************************

#include <stdio.h>
