Question

C语言编程序：计算数列1+1/2+1/3+1/4+...+1/100的和并输出 帮一下 吧

Answer 1

#include <stdio.h>
int main(void)
{
double count = 0;
int turn;
for(turn=1; turn<=100; turn++) {
count = count + (1 / (double) turn);
}
printf("%Lf\n", count);
return 0;
}
输出测试:
5.187378

Answer 2

#include"stdio.h"
int main(void)
{
int n=100;
int i;
float sum=0;
for(i=1;i<=n;i++){
sum+=(1.0/i);
}
printf("%f",sum);
return 0;
}
