C Program to Find the Sum of n odd Numbers
In this article, we are going to write a c program to find the Sum of n odd numbers
We will make this program in the following way -:
- C Program to Find the Sum of n odd Numbers in a Given Range (Using For Loop)
- C Program to Find the Sum of n odd Numbers Using While Loop
- C Program to Find the Sum of n odd Numbers Using Do While Loop
- C Program to Find the Sum of n odd Numbers Using Function
To make this program, we will use the following concept given below. If you do not know about these topics well, then you may not understand this program, so you should know about them in detail from the link given below.
Now without wasting time let’s start programming.
C Program to Find the Sum of n odd Numbers in a Given Range (Using For Loop)
Algorithm
- Program Start
- Variable Declaration (num1,num2,i,sum)
- Input Numbers
- Calculating Sum
- Displaying the Sum of n Odd Numbers in a Given Range
- Program End
Program
//C Program to Find the Sum of n odd Numbers in a Given Range (Using For Loop)
#include<stdio.h>
void main()
{
//Declaring Variable
int num1, num2, i, sum = 0 ;
//Input Number
printf("Enter Starting Number\n");
scanf("%d",&num1);
printf("Enter Ending Number\n");
scanf("%d",&num2);
for(i=num1;i<=num2;i++)
{ if(i%2==0)
{
continue ;
}
else
{
sum = sum + i;
}
}
printf("\nSum of odd Numbers in Given Range : %d", sum);
}
Output
Enter Starting Number
1
Enter Ending Numeber

Sum of odd Numbers in Given Range : 9C Program to Find the Sum of n odd Numbers Using While Loop
Program
//C Program to Find the Sum of n odd Numbers in a Given Range Using while Loop
#include<stdio.h>
int main()
{
//Declaring Variable
int num1, num2, sum = 0 ;
//Input Number
printf("Enter Starting Number\n");
scanf("%d",&num1);
printf("Enter Ending Number\n");
scanf("%d",&num2);
while(num1<=num2)
{ if(num1%2 != 0)
{
sum = sum + num1;
}
num1++;
}
printf("\nSum of odd Numbers in Given Range : %d", sum);
return 0;
}
Output
Enter Starting Number
10
Enter Ending Numeber

//Input Number
printf("Enter Starting Number\n");
scanf("%d",&num1);
printf("Enter Ending Number\n");
scanf("%d",&num2);
do
{ if(num1%2 != 0)
{
sum = sum + num1;
}
num1++;
}while(num1<=num2);
printf("\nSum of odd Numbers in Given Range : %d", sum);
return 0;
}Output
Enter Starting Number
11
Enter Ending Numeber

Sum of odd Numbers in Given Range : 75C Program to Find the Sum of n odd Numbers Using Function
To Calculate the sum n odd numbers through a function, first you need to know about the function. You can read about the function from the link given below.
Algorithm
- Program Start
- Declaring variables
- Input Number
- Calling Function to calculate Sum of n odd Numbers
- Print the Sum of n odd Numbers
- Program End
Program
//C Program to Find the Sum of n odd Numbers in a Given Range Using Function
#include<stdio.h>
int sum(int , int);
void main()
{
//Declaring Variable
int num1, num2, s ;
//Input Number
printf("Enter Starting Number\n");
scanf("%d",&num1);
printf("Enter Ending Number\n");
scanf("%d",&num2);
s = sum(num1, num2);
printf("\nSum of odd Numbers in Given Range : %d", s);
}
int sum(int num1, int num2)
{
int sum = 0;
do
{
if(num1%2 != 0)
{
sum = sum + num1;
}
num1++;
}while(num1<=num2);
return sum;
}Output
Enter Starting Number
1
Enter Ending Numeber
