Sum of numbers from 1 to 100 in c

May 22, 2018 · To get the result in O(1) time we can use the formula of summation of n natural numbers.For the above example, a = 4 and N = 23, number of multiples of a, m = N/a(integer division). The multiples are 4, 8, 12, 16, 20.

Sum can be obtained in many ways.One of the way is using for loop. Code is - #include<stdio.h> main() { int i,sum=0; for(i=1;i<=100;i++) { sum=sum+i; } printf(“Sum of nos 1 to 100 =%d”,sum); }

Hence, required sum of the integers between 100 and 200 that are divisible by 9 is 1683. (ii) The sum of the integers between 100 and 200 which is not divisible by 9 = (sum of total numbers between 100 and 200) – (sum of total numbers between 100 and 200 which is divisible by 9). Hence, the required sum is 13167. Question 6:

Sep 15, 2010 · Therefore, the sum of the numbers from 1 through 6 maybe expressed as (6/2)(6+1) = 3 (7) = 21. Now try a few examples and see if our the pattern holds. If we use this pattern, we can easily add the number from 1 through 100. We have the following pairs: (1 + 100), (2 +99), (3 + 98) and so on (see figure below). That is, we have 100/2 pairs of ...

The digit sum of any number base k is equivalent to its remainder upon division by (k-1). For binary numbers, number expressed to base 2, the proposition is true but rather bizarre. The digit sum of any binary number except zero is one and the remainder of any number upon division by one is zero.

Apr 23, 2000 · A formula young Gauss discovered when trying to add the numbers 1-100, which goes n (n+1)/2, which is (50*51)/2, or 5050. He found it by discovering that 100+1=101, 99+2=101, 3+98=101...50+51=101. He found out that by wrapping the numbers around, that is adding (100-1) and (1-100) together, he would get the number 100 at every term.
Jul 15, 2019 · The sum of odd numbers are: 105 The sum of even numbers are: 120. Methodology: First, define an array with elements. Next, declare and initialize two variables to find sum as oddSum=0, evenSum=0. Then, use the “for loop” to take the elements one by one from the array.
Lets you pick a number between 1 and 100. Use the start/stop to achieve true randomness and add the luck factor. Pick unique numbers or allow duplicates.
