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);
}

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;

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
