C++ program tutorials to print sum of Series

C++ program to print sum of numbers from 1+2+3+.10

Sam Sir

// program name test035.cpp

// print sum of no from 1+2+3+....10

# include <iostream.h>

# include <conio.h>

void main()

{

int no,s=0;

for (no=1;no<=10;no++)

s=s+no;

cout<<"Sum of nos from 1 to 10 = "<<s<<"\n";

getch();

}

Output

Sum of nos from 1 to 10 = 55

 

  • Now make few changes and keep two statements s=s+no; and make following changes in printf statements withing { } brace brackets.

 

C++ program to print series of sum of numbers from 1+2+3+.10

Sam Sir

// program name test035.c

// print sum of no from 1+2+3+....10

# include <iostream.h>

# include <conio.h>

void main()

{

int no,s=0;

for (no=1;no<=10;no++)

{ s=s+no;

cout<<"Sum + "<<no<<" = "<<s<<"\n";

}

getch();

}

Output

Sum + 1 = 1

Sum + 2 = 3

Sum + 3 = 6

Sum + 4 = 10

Sum + 5 = 15

Sum + 6 = 21

Sum + 7 = 28

Sum + 8 = 36

Sum + 9 = 45

Sum + 10 = 55

 


C++ Program to calculate and print product of numbers from 1 to 10

Sam Sir

// program name test036.cpp

// print product of nos from 1*2*3*....10

# include <iostream.h>

# include <conio.h>

void main()

{

int no,p=1;

for (no=1;no<=10;no++)

p=p*no;

cout<<"Product of nos from 1 to 10 = "<<p;

getch();

}

Output

Product of nos from 1 to 10 = 24320

 

C Program print sum of 2 digit odd nos from 11+13+15....99

Sam Sir

// program name test037.cpp

// print sum of 2 digit odd nos from 11+13+15....99

# include <iostream.h>

# include <conio.h>

void main()

{

int no,s=0;

for (no=11;no<=99;no=no+2)

s=s+no;

cout<<"Sum of 2 digit odd nos from 11 to 99 = "<<s;

getch();

}

Output

Sum of 2 digit odd nos from 11 to 99 = 2475

 

C++ Program print sum of 2 digit nos divisible by 3 and 5

Sam Sir

// program name test038.cpp

// print sum of 2 digit nos divisible by 3 and 5

# include <iostream.h>

# include <conio.h>

void main()

{

int no,s=0;

for (no=10;no<=99;no++)

{ if (no%3==0 && no%5==0)

s=s+no;

}

cout<<"Sum of 2 digit nos divisible by 3 and 5 = "<<s;

getch();

}

Output

Sum of 2 digit nos divisible by 3 and 5 = 315

 


C++ program to print sum of series as 1+ 1/2+ 1/3+ 1/4 ....1/10

Sam Sir

// program name test039.cpp

// print sum of series as 1+ 1/2+ 1/3+ 1/4 ....1/10

# include <iostream.h>

# include <conio.h>

void main()

{

float no,s=0.0;

for (no=1;no<=10;no++)

{s = s+(1.0/no);

cout<<"\nSum of series as 1+ 1/2+ 1/3+ 1/4 ....1/10 = "<<s;

}

getch();

Sum of series as 1+ 1/2+ 1/3+ 1/4 ....1/10 = 2.92897

 

C++ program to print sum of series as 1/2+ 2/3+ 3/4 ....9/10

Sam Sir

// program name test040.cpp

// print sum of series as 1/2+ 2/3+ 3/4 ....9/10

# include <iostream.h>

# include <conio.h>

void main()

{

float no,s=0.0;

for (no=1;no<=9;no++)

{s = s+(no/(no+1));

cout<<"\nSum of series as 1/2+ 2/3+ 3/4 ....9/10 = "<<s;
