编程求1/2+1/3+1/4的和

#include<stdio.h>
void main(){
int i;
double sum=0;
for(i=2;i<=4;i++){
sum+=1.0/i;
}
printf("%lf",sum);
}

#includeint main(){ double sum1 = 0.0; double sum2 = 0.0; for(int i=1;i<=100;i+=2){ sum1 += 1.0/i; } for(int i=1;i<=100;i++){ sum2 += 1.0/i; } printf(" %lf %lf\n",sum1,sum2); return 0;}
