PROGRAM 34

Object

Write a program to print the sum of first 10 numbers horizontally.

Algorithm

1. Declare integer variables sum and i.
2. Set sum = 0.
3. Repeat FOR i = 1 to 10 by 1
   • sum = sum + i
   • Write “i +”.
   • [End of FOR loop.]
4. Write “= sum”.
5. Exit.

Flowchart

C++ Source Code

// program 34
#include<iostream>
using namespace std;

int main()
{
  int i, sum = 0;
  for (i = 1; i <= 10; i++)
  {
    sum = sum + i;
    cout << i << " + ";
  }
  cout << "\b\b= " << sum;
  return 0;
}

C Source Code

/*program 34*/
#include<stdio.h>

int main()
{
  int i, sum=0;
  for(i=1; i<=10; i++)
     {
     sum = sum + i;
     printf("%d + ", i);
     }
  printf("\b\b= %d", sum);
  return 0;
}

Output

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 = 55
