c语言求两个数之间的和跟差

#includestdio.h

voidmain()

{

inta,b;

printf(“请输入两个整数:”);

scanf(“%d%d”,a,b);

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

}

C语言求两个数的和差积商余数

#include”stdib.h”

#include”stdlib.h”

intmain()

{

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

floatd;

printf(“输入两个人整数：”);

scanf(“%d%d”,sum1,sum2);

if(sum2==0){

a=num1+num2;

b=num1-num2;

c=num1*num2;

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

system(“pause”);

return0;

}

C语言中求两个数的差程序如何编写

直接定义两个变量，然后输出相差结果就可以了。掌握基本的语法知识就挺好写的

请用C++ 编写程序，计算结果保存在TXT

楼上大哥,问题补充有误，担忧乘不上下面的只能用这个形式：呵呵

我用的是VC ++编译，并且我需要复制过去就直接能编译的程序，因为我vc还不是很了解！

麻烦你了

还有能不能将运行结果导入excle结果最好500*500显示！

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

其他地方可以改

下层则是出现这种情况：

怎么修改。

c语言求差程序

代码参考：

#includestdio.h

void main()

{

int a,b,c;

printf(“减数:”);

scanf(“%d”,a);

printf(“被减数:”);

scanf(“%d”,b);

c=a-b;

printf(“减数减去被减数的差为%d\n”,c);

}

C语言：一组数，求这组数相邻差值最小的的两个数并指出他们所在的位置

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

c语言求两个数的差值

既然只有两个值并且是int可以相减取绝对值.

printf(“The result is:%d”,abs(x-y));

记得要#include math.h
