c語言求兩個數之間的和跟差

#includestdio.h

voidmain()

{

inta,b;

printf(“請輸入兩個整數:”);

scanf(“%d%d”,a,b);

printf(“%d+%d=%d\t%d-%d=%d”,a,b,a+b,a,b,a-b);

}

C語言求兩個數的和差積商餘數

#include”stdib.h”

#include”stdlib.h”

intmain()

{

intnum1,num2,a,b,c,e;

floatd;

printf(“輸入兩個人整數：”);

scanf(“%d%d”,sum1,sum2);

if(sum2==0){

a=num1+num2;

b=num1-num2;

c=num1*num2;

printf(“和%d,差%d,積%d”，a,b,c);}

else(sum2!=0){

a=num1+num2;

b=num1-num2;

c=num1*num2;

d=num1/num2;

e=num1%num2;

printf(“和%d,差%d,積%d,商%f,餘數%d”a,b,c,d,e);}

system(“pause”);

return0;

}

C語言中求兩個數的差程序如何編寫

直接定義兩個變量，然後輸出相差結果就可以了。掌握基本的語法知識就挺好寫的

請用C++ 編寫程序，計算結果保存在TXT

樓上大哥,問題補充有誤，擔憂乘不上下面的只能用這個形式：呵呵

我用的是VC ++編譯，並且我需要複製過去就直接能編譯的程序，因為我vc還不是很了解！

麻煩你了

還有能不能將運行結果導入excle結果最好500*500顯示！

若excle不顯示500*500，可以修改x=x+0.14和 y=y+0.14，顯示100*100的！

其他地方可以改

下層則是出現這種情況：

怎麼修改。

c語言求差程序

代碼參考：

#includestdio.h

void main()

{

int a,b,c;

printf(“減數:”);

scanf(“%d”,a);

printf(“被減數:”);

scanf(“%d”,b);

c=a-b;

printf(“減數減去被減數的差為%d\n”,c);

}

C語言：一組數，求這組數相鄰差值最小的的兩個數並指出他們所在的位置

#includemath.h

float dx=1e30;

int k;

for(int i=0;i29;i++)

if(fabs(a[i+1]-a[i])dx){dx=fabs(a[i+1]-a[i]); k=i;}

printf(“差值最小的是下標%d和%d：|%d-%d|=%d\n”,k,k+1,a[k+1],a[k],dx);

c語言求兩個數的差值

既然只有兩個值並且是int可以相減取絕對值.

printf(“The result is:%d”,abs(x-y));

記得要#include math.h
