C

a program to find the sum of all the odd numbers upto a given lnumber in c

int limit,i,sum=0;
	setbuf(stdout,NULL);
	printf("Enter a limit");
	scanf("%d",&limit);
	for(i=1;i<=limit;i++){
		if(i%2!=0){
			printf("%d
", i);
			sum=sum+i;
		}

	}
	printf("The sum of odd numbers from 0 to %d are :%d",limit,sum);

C program to calculate the sum of odd and even numbers

#include <stdio.h>void main(){int i, number, odd_sum = 0, even_sum = 0;printf("Enter the value of number
");scanf("%d", &number);for (i = 1; i <= number; i++){if (i % 2 == 0)even_sum = even_sum + i;elseodd_sum = odd_sum + i;}printf("Sum of all odd numbers = %d
", odd_sum);printf("Sum of all even numbers = %d
", even_sum);}
