C program to find sum of series 1+1/2+1/3+1/4+1/5........+1/N - My CS Tutorial

In this tutorial we will learn how to write a program that print the sum of a series.If the series is...

1+1/2+1/3+1/4+1/5........+1/N

C program code

#include<stdio.h>

#include<conio.h>

void main()

{

int a,num;

float sum=0;

printf("\n Enter the range of series:\n ");

scanf("%d",&num);

for(a=1;a<=num;a++)

{

 sum+=(float)1/a;

}

printf("\n The value of series:\n ");

for(a=1;a<=num;a++)

{

 if(a<num)

 {

  printf("1/%d + ",a);

 }

 else

 {

  printf("1/%d = ",a);

 }

}

printf("%f\n",sum);

getch();

}

OUTPUT:

In this output the value of number(range) is 7

The series is
1+1/2+1/3+1/4+1/5+1/6+1/7

And the sum of this series is 2.592857
