编写C程序:求1\/1!+1\/2!+1\/3!+...+1\/n!(n!=1*2*3*4...n)急!急!帮帮啊...
int i,n,j=1;double sum=0;printf("输入n的值:");scanf("%d",&n);for(i=1;i<=n;i++){ j=j*i;sum=sum+(1\/double(j));printf("%d ,%f\\n",j,sum);} printf("sum=%f\\n",sum);}
用C语言,编写求n的阶乘的函数,求1\/1!+1\/2!+1\/3!+…1\/n!,直到最后两项...
答案是1.718282 代码如下:include <stdio.h> int main(){ double res=0.0, tmp=1.0;int i=1;while(1){ if(tmp*i\/(i+1)<1e-5)break;tmp\/=i;res += tmp;i++;} printf("%lf\\n", res);return 0;}
...输入一个正整数n,求1\/1!+1\/2!+1\/3!+……1\/n!的值。谢谢
int i ,n ,t=1 ;float s=0;printf("\\n请输入 n :");scanf("%d,",&n);for(i = 1;i<=n;i++){ t=t*i ;s+=1\/t ; } printf("S=%f ", s);getch();}
用C语言编写程序,求1+1\/(1+2)+1\/(1+2+3)+... +1\/(1+2+...+n),并将...
include<stdio.h> int main(){ int n,j;float sum=0,s=0;printf("请输入n的值:");scanf("%d",&n);for(j=1;j<=n;j++){ sum=sum+j;s=s+1\/sum;} printf("%g",s);return 0;} 需注意詹俊峰给的是典型的错误答案,请楼主思考为什么。
C++ 编写函数,计算1\/1!+1\/2!+1\/3!+ … +1\/n!。在主函数中输入n的值...
);result = fun(n);cout << setiosflags(ios::fixed) << setprecision(2) << result << "\\n";return 0;}double fun(int a){double s = 0;int i = 0, temp = 1;for (i = 1; i <= a; i++){temp *= i;s += 1.0 \/ temp;}return s;} 满足你要求了吧。嘿嘿!
