Program to Print Number Series in C

In c language you can print any number series. Here i will show you how to print number series in c language with explanation. In case of print number series you need to focus on common difference between two numbers..

C program to Calculate 1 + 2 + 3 + 4 + 5 + ... + n series

#include<stdio.h>
#include<conio.h>

void main()
{
int i,n,sum=0;
clrscr();
    n=10;
    for(i=1;i<=n;i++)
    {
        sum+=i;
    }
    printf("Sum: %d",sum);
getch();
}

Sum: 55

C program to Calculate (1*1) + (2*2) + (3*3) + (4*4) + (5*5) + ... + (n*n) series

#include<stdio.h>
#include<conio.h>

void main()
{
int i,n,sum=0;
 clrscr();
	n=10;
    for(i=1;i<=n;i++)
    {
        sum+=i*i;
    }
    printf("Sum: %d",sum);
getch();
}

Sum: 385

C program to Calculate (1) + (1+2) + (1+2+3) + (1+2+3+4) + ... + (1+2+3+4+...+n) series

#include<stdio.h>
#include<conio.h>

void main()
{
 int i,j,n,sum=0;
 clrscr();
    n=10;
    for(i=1;i<=n;i++)
    {
        for(j=1;j<=i;j++)
        {
            sum+=j;
        }
    }
    printf("Sum: %d",sum);
getch();
}

Sum:385
