最簡單的c語言代碼

A. 寫一個簡短的C語言代碼

#include<stdio.h>

intmain()
{
	屬doublea,b,c;
	scanf("%lf",&a);
	scanf("%lf",&b);
	c=a+b;
	printf("firstnumber:%.2lf",a);
	printf("
secondnumber%.2lf",b);
	printf("
	%.2lf",a);
	printf("
+	%.2lf",b);
	printf("
-------------
");
	printf("	%.2lf
",c);

	return0;
}

B. 求寫一個簡單的c語言代碼，要最簡單的那種。謝謝

//#include"stdafx.h"//Ifthevc++6.0,withthisline.
#include"stdio.h"
intmyfact(intn){
if(n==1||n==0)
return1;
elsereturnn*myfact(n-1);
}
intmain(void){
intN,sum;
while(1){
printf("InputN(0<=N<=100000letterend)...
N=");
if(scanf("%d",&N)<=0)
break;
if(N>=0&&N<=100000){
for(sum=0;N;sum+=myfact(N%10),N/=10);
printf("Theresultis%d.
",sum);
}
elseprintf("Error,redo:");
}
return0;
}
