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

#include <stdio.h>

int main()
{
int a,b;
while( scanf( "%d%d" , &a , &b ) != EOF ) //輸入直到文件結尾
{
printf( "%d\n" , a+b ); //一行一個結果
}
return 0;
}

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語言數組怎麼輸出全部

C語言數組輸出全部步驟如下:

1、首先打開c語言項目,然後創建一個int類型的數組。

㈢ c語言中,一次連續輸入多組數據,並且最後連續輸出多組結果,應該用哪種方法

用二維數組就可以實現一次連續輸入多組數據。思路是嵌套循環,外層循環控制二維數組的行數(也就是第幾組數據),內層循環控制這組數據中數據個數。
採用二維數組方法的有點在於,這種隨機存取的數據結構方便查找和檢索,但一定要注意這種方法不便於向已有數據中插入和刪除數據。

㈣ c語言,如何實現多組數據結果對應輸出

可以嘗試用while(scanf("%d%d",&a,&b)==2) 只不過在輸入下一組數據前不要回車,否則就直接輸出了,並且n也失去了意義,如果你實在不嫌煩的話就把a+b的值儲存在數組中然後循環輸出。
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語言如何輸入多組數據後再輸出多組數據(未規定多少組)

應該用循環將多組數組輸入到一個二維數組中然後再用循環嵌套將數組中的值做比較,一般設每行的第一個值,讓他和每行數組的其它值做比較,找到比它小的就進行交換(冒泡排序法);然後循環輸出,代碼我就不打了,如果樓主想要學好c語言,這些都是基礎,要多練

㈥ c語言循環中如何輸出多個數組

C語言輸出數組時,需要根據數組下標,或者指針移動進行輸出。

所以,一般不會用一個循環輸出多個數組,這樣操作不方便,而且降低效率。

常規的做法是,在多個循環中,各自輸出不同的數組。

示例代碼如下:

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

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

return0;
}

㈦ c語言如何實現字元的批量輸入和批量輸出

你可以用讀取文件的方法批量輸入。
FILE
*fp=fopen("文件路徑.文件名.後綴","rb+"));
fscanf(fp,"%變數類型",&變數名);
有規律的字元或者隨機字元,也可以通過循環來批量輸入。『

㈧ C語言中如何實現輸入輸出多組數據,該如何結束輸入

c語言中實現多組數據輸入輸出主要有兩種方式:
1.首先輸入一個n,表示將有n個輸入輸出,例如:
#include
int main()
{
int n,a;
scanf("%d",&n);
while(n--){

scanf("%d",&a);

printf("輸出:%d\n",a);
}
return 0;
}
/*
運行結果:
3
255
輸出:255
156
輸出:156
125
輸出:125
*/2.使用while(scanf("%d",&n)!=eof){}語句,直達輸入ctrl+z,結束輸入,例如:
#include
int main()
{
int a;
while(scanf("%d",&a)!=eof){

printf("輸出:%d\n",a);
}
return 0;
}
/*
運行結果:
54
輸出:54
5156
輸出:5156
21
輸出:21
^z
*/

㈨ C語言如何多組數據輸入輸出

#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

㈩ c語言如何用switch進行多次輸出

提問者沒有把問題描述清楚。如果這個語句放在循環體中,那麼隨著循環執行多次,它就可以進行多次的輸出。另外如果在多個case中,進行輸出以後,沒有使用break語句進行中斷,那麼它會繼續往下之前下面的後續的輸出語句。
