How do you find the sum of odd and even numbers in C?

The program output is also shown below.

1. #include
2. void main()
3. {
4. int i, num, odd_sum = 0, even_sum = 0;
5. printf(“Enter the value of num\n”);
6. scanf(“\%d”, #);
7. for (i = 1; i <= num; i++)
8. {

How do you add numbers in a loop in C++?

You can try: int sum = startingNumber; for (int i=0; i < positiveInteger; i++) { sum += i; } cout << sum; But much easier is to note that the sum 1+2+… +n = n*(n+1) / 2 , so you do not need a loop at all, just use the formula n*(n+1)/2 .

What is loop syntax?

The syntax of a for loop in C programming language is − for ( init; condition; increment ) { statement(s); } Here is the flow of control in a ‘for’ loop − The init step is executed first, and only once. This step allows you to declare and initialize any loop control variables.

How do you add odd numbers to a number?

The total of any set of sequential odd numbers beginning with 1 is always equal to the square of the number of digits, added together. If 1,3,5,7,9,11,…, (2n-1) are the odd numbers, then; Sum of first odd number = 1. Sum of first two odd numbers = 1 + 3 = 4 (4 = 2 x 2).

How do you sum only even numbers in C?

Program: Write a program to find the sum of even numbers in C language.

1. #include
2. int main()
3. {
4. int i, n, sum=0;
5. printf(“Enter any number: “);
6. scanf(“\%d”, &n);
7. for(i=2; i<=n; i+=2)
8. {

How do you add odd and even numbers in Python?

In this python program to find Sum of Even and Odd Numbers in a List, User entered items = [2, 3, 4, 5], Even_Sum = 0, Odd_Sum = 0. if(NumList[1] \% 2 == 0) => if(3 \% 2 == 0) – Condition is False, so it enters into the Else block. if(5 \% 2 == 0) – Condition is False, so it enters into Else block.

What is 30/2 as a sum in C programming?

In our C Programming example, it is 30/2 = 15 This program allows the user to enter the number (n) he wishes to calculate the average and sum. Next, it will ask the user to enter individual items up to a declared number.

How to calculate sum and average in C programming?

This C program allows the user to enter the number (n) he wishes to calculate the average and sum. Next, it will ask the user to enter individual item up to a declared number. Using the For loop in C Programming it will calculate the sum and later it will calculate the average.

How to find sum of all even numbers in C programming?

If condition checks whether the remainder of the number divided by 2 is exactly equal to 0 or not. If the condition is True, then it is Even number, and the C Programming compiler will add i value to sum. This program to find Sum of all Even Numbers is the same as above.

How to find average of N number in C program?

The code analysis behind this C program to find Average of n Number The first printf statement will ask the user to enter n value. For example, if the user enters 2, then the second printf statement will ask the user to enter those two values, one after the other.
