C Exercises: Sum of n odd numbers starting from m

C Basic Declarations and Expressions: Exercise-123 with Solution

Write a C program that reads two integers m, n and compute the sum of n odd numbers starting from m.

Sample Solution:

C Code:

#include <stdio.h>
int main ()
{

  int m, n, i, j, k, sum_odd_nums = 0;

  printf("\nInput two integes (m, n):\n");
  scanf("%d %d", &m, &n);

  printf("\nSum of %d odd numbers starting from %d: ",n,m);
   for (k = 0, j = m; k < n; j++)
    {

      if (j % 2 != 0)
      {

        sum_odd_nums += j;
        k++;

      }
    }

    printf("\n%d", sum_odd_nums);
  }

Sample Output:

Input two integes (m, n):
65
5

Sum of 5 odd numbers starting from 65:
345

C Programming: Tips of the Day

Static variable inside of a function in C

The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().

The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.

The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
