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

#include <stdio.h>

int main()
{
int a,b;
while( scanf( "%d%d" , &a , &b ) != EOF ) //输入直到文件结尾
{
printf( "%d\n" , a+b ); //一行一个结果
}
return 0;
}

输入格式:每行输入一组case,当case中的数据满足某种情况时退出
输出格式:一行一个结果
Problem Description
Your task is to Calculate a + b.

Input
Input contains multiple test cases. Each test case contains a pair of integers a and b, one pair of integers per line. A test case containing 0 0 terminates the input and this test case is not to be processed.

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.

㈡ C语言数组怎么输出全部

C语言数组输出全部步骤如下:

1、首先打开c语言项目,然后创建一个int类型的数组。

㈢ c语言中,一次连续输入多组数据,并且最后连续输出多组结果,应该用哪种方法

用二维数组就可以实现一次连续输入多组数据。思路是嵌套循环,外层循环控制二维数组的行数(也就是第几组数据),内层循环控制这组数据中数据个数。
采用二维数组方法的有点在于,这种随机存取的数据结构方便查找和检索,但一定要注意这种方法不便于向已有数据中插入和删除数据。

㈣ c语言,如何实现多组数据结果对应输出

可以尝试用while(scanf("%d%d",&a,&b)==2) 只不过在输入下一组数据前不要回车,否则就直接输出了,并且n也失去了意义,如果你实在不嫌烦的话就把a+b的值储存在数组中然后循环输出。
int sum[10];
int i=0,j;
while(n--)
{
scanf("%d%d",&a,&b);
sum[i++]=a+b;
}
for(j=0;j<i-1;j++)
printf("%d ",sum[j]);
printf("%d\n",sum[j]);

㈤ C语言如何输入多组数据后再输出多组数据(未规定多少组)

应该用循环将多组数组输入到一个二维数组中然后再用循环嵌套将数组中的值做比较,一般设每行的第一个值,让他和每行数组的其它值做比较,找到比它小的就进行交换(冒泡排序法);然后循环输出,代码我就不打了,如果楼主想要学好c语言,这些都是基础,要多练

㈥ c语言循环中如何输出多个数组

C语言输出数组时,需要根据数组下标,或者指针移动进行输出。

所以,一般不会用一个循环输出多个数组,这样操作不方便,而且降低效率。

常规的做法是,在多个循环中,各自输出不同的数组。

示例代码如下:

#include<stdio.h>
intmain()
{
inta[10],b[20];
inti;
for(i=0;i<10;i++)
scanf("%d",a+i);//输入a
for(i=0;i<20;i++)
scanf("%d",b+i);//输入b

for(i=0;i<10;i++)
printf("%d,",a[i]);//输出a
for(i=0;i<20;i++)
printf("%d,",b[i]);//输出b

return0;
}

㈦ c语言如何实现字符的批量输入和批量输出

你可以用读取文件的方法批量输入。
FILE
*fp=fopen("文件路径.文件名.后缀","rb+"));
fscanf(fp,"%变量类型",&变量名);
有规律的字符或者随机字符,也可以通过循环来批量输入。‘

㈧ C语言中如何实现输入输出多组数据,该如何结束输入

c语言中实现多组数据输入输出主要有两种方式:
1.首先输入一个n,表示将有n个输入输出,例如:
#include
int main()
{
int n,a;
scanf("%d",&n);
while(n--){

scanf("%d",&a);

printf("输出:%d\n",a);
}
return 0;
}
/*
运行结果:
3
255
输出:255
156
输出:156
125
输出:125
*/2.使用while(scanf("%d",&n)!=eof){}语句,直达输入ctrl+z,结束输入,例如:
#include
int main()
{
int a;
while(scanf("%d",&a)!=eof){

printf("输出:%d\n",a);
}
return 0;
}
/*
运行结果:
54
输出:54
5156
输出:5156
21
输出:21
^z
*/

㈨ C语言如何多组数据输入输出

#includeintpow(inta,intn)//计算a的n次方{if(n==1)returna;returna*pow(a,n-1);}intmain(){intT;intn,k,sum,i;scanf("%d",&T);while(T--){sum=0;scanf("%d%d",&n,&k);for(i=1;i

㈩ c语言如何用switch进行多次输出

提问者没有把问题描述清楚。如果这个语句放在循环体中,那么随着循环执行多次,它就可以进行多次的输出。另外如果在多个case中,进行输出以后,没有使用break语句进行中断,那么它会继续往下之前下面的后续的输出语句。
