**C Program to find Sum of numbers in a given range**

#include <stdio.h>

int main()

{

int fvalue,lvalue,sum=0;

printf("Enter the first and last value: ");

scanf("%d %d",&fvalue,&lvalue);

for(int i=fvalue;i<=lvalue;i++)

sum=sum+i;

printf("%d",sum);

return 0;

}

**C++ Program to find Sum of numbers in a given range**

#include <iostream>

using namespace std;

int main()

{

int first,last,sum=0;

cout<<"Enter the first and last values: ";

cin>>first>>last;

for(int i=first;i<=last;i++)

sum=sum+i;

cout<<sum;

return 0;

}

**Java Program to find Sum of numbers in a given range**

import java.util.Scanner;

public class Main

{

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

System.out.print("Enter a number: ");

int first = sc.nextInt();

int last = sc.nextInt();

int sum= 0;

for(int i=first;i<=last;i++)

sum = sum + i;

System.out.print(sum);

}

}

**Python Program to find Sum of numbers in a given range**

first=int(input("Enter first value: "))

last=int(input("Enter last value: "))

Sum=0

for i in range(first,last+1):

Sum=Sum+i

print(Sum)
