1. C語言 輸入包含多組測試數據
#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語言中如何實現多組數據輸入輸出
仔細認真看看下面的會對你有幫助的，嘿嘿
輸入格式：有多個case輸入，直到文件結束
輸出格式：一行一個結果
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

3. C語言中如何實現輸入輸出多組數據，該如何結束輸入
第一行是不是輸入n（將來要輸入的數字個數）？如果，不是的話你需要定義一個符號用來結束。
4. c語言如何輸入多組數據
#include<stdio.h>
intmain()
{
intn;
scanf("%d",&n);
while(n!=0)//等於0就退出，不等於0就繼續輸入
{
scanf("%d",&n)；
printf("%d ",n);
}
}
5. c語言--多組數據的輸入怎麼輸啊
就這態度.... 就是會也沒人把源碼貼上來....
這年頭... 有兩分就把自己當大爺...
在別人眼裡啥樣自己永遠不清楚...
在這里發問題是來尋求幫助的,別人幫助了是別人好心,應該心存感恩 不要老把自己放的高高在上, 貌似沒見過有哪條河是從山谷流向山峰的吧?...
6. c語言 怎麼實現多組數據的同時輸入和輸出
不可以，因為它是串列執行的，不是並行執行的。
7. C語言如何實現輸入數據有多組，輸入以0 0結束。
可以循環輸入數據，當遇到輸入的值均為0時結束輸入。
以輸入整型為例，代碼如下：
int a,b; //用來存輸入的數據。
while(1)
{
scanf("%d%d",&a,&b);//以0 0結束輸入，所以輸入時是以空白字元分隔的。
if(a == 0 && b == 0) break; //當輸入的全為0，結束輸入。
//在這里添加使用輸入數據的代碼。
}
8. 如何設計輸入處理多組數據的c語言程序
方法一；自定義函數，參數傳遞多組數據變數地址。這樣對原數據處理，原變數值就改變了。
方法二:直接將數據定義成全局變數。
方法三:定義數組或結構體，將處理後的多組數據作為返回值返回。
方法四:一個函數要處理不定個數的參數，按最大參數個數接收，約定空值，之後在函數內做判斷。
9. c語言如何實現輸入數據有多組
#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結束就把0替換EOF
{
printf("%d\n",a+b);
}
}

#includeintpow(inta,intn)//計算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
