1. C语言 输入包含多组测试数据
#include<stdio.h>
int main()
{
int C,t;
char s[60];
int i,j;
scanf("%d ",&C);
for (i=0;i<C;i++){
scanf("%d ",&t);
fgets(s,60,stdin);
for (j=0;j<t;j=j+2){
printf("%c%c",s[j+1],s[j]);
}
}
return 0;
}
2. 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

3. C语言中如何实现输入输出多组数据，该如何结束输入
第一行是不是输入n（将来要输入的数字个数）？如果，不是的话你需要定义一个符号用来结束。
4. c语言如何输入多组数据
#include<stdio.h>
intmain()
{
intn;
scanf("%d",&n);
while(n!=0)//等于0就退出，不等于0就继续输入
{
scanf("%d",&n)；
printf("%d ",n);
}
}
5. c语言--多组数据的输入怎么输啊
就这态度.... 就是会也没人把源码贴上来....
这年头... 有两分就把自己当大爷...
在别人眼里啥样自己永远不清楚...
在这里发问题是来寻求帮助的,别人帮助了是别人好心,应该心存感恩 不要老把自己放的高高在上, 貌似没见过有哪条河是从山谷流向山峰的吧?...
6. c语言 怎么实现多组数据的同时输入和输出
不可以，因为它是串行执行的，不是并行执行的。
7. C语言如何实现输入数据有多组，输入以0 0结束。
可以循环输入数据，当遇到输入的值均为0时结束输入。
以输入整型为例，代码如下：
int a,b; //用来存输入的数据。
while(1)
{
scanf("%d%d",&a,&b);//以0 0结束输入，所以输入时是以空白字符分隔的。
if(a == 0 && b == 0) break; //当输入的全为0，结束输入。
//在这里添加使用输入数据的代码。
}
8. 如何设计输入处理多组数据的c语言程序
方法一；自定义函数，参数传递多组数据变量地址。这样对原数据处理，原变量值就改变了。
方法二:直接将数据定义成全局变量。
方法三:定义数组或结构体，将处理后的多组数据作为返回值返回。
方法四:一个函数要处理不定个数的参数，按最大参数个数接收，约定空值，之后在函数内做判断。
9. c语言如何实现输入数据有多组
#include <stdio.h>
void main()
{
int a,b,n;
scanf("%d",&n);
while(n<1||n>10)
{
printf("Error!!");
scanf("%d",&n);
}
while (n--)
{
scanf("%d%d",&a,&b);
printf("%d\n",a+b);
}
}
//*************************************************
#include <stdio.h>
void main()
{
int a,b;
while (scanf("%d%d",&a,&b)!=EOF)//以0结束就把0替换EOF
{
printf("%d\n",a+b);
}
}
