Write a while loop that adds the first 100 numbers (from 1 to 100) together. To do so, use a while loop that continues while the condition of cur_num being less than or equal to stop_num is True. Inside the loop, it should add cur_num to the running total variable, and also add 1 to cur_num. Make sure to check at the end that the value of total reflects the total summation.

I am writing JAVA and C++ program. Let me know if you want the program in some other programming language.  

Explanation:

JAVA program:

public class SumOfNums{

public static void main(String[] args) { //start of main function

int cur_num   = 1; // stores numbers

int stop_num= 100; // stops at this number which is 100

int total = 0; //stores the sum of 100 numbers

/* loop takes numbers one by one from cur_num variable and continues to add them until the stop_num that is 100 is reached*/

while (cur_num <= stop_num) {

 total += cur_num; //keeps adding the numbers from 1 to 100

//increments value of cur_num by 1 at each iteration

 cur_num = cur_num + 1;}

//displays the sum of first 100 numbers

System.out.println("The sum of first 100 numbers is: " + total);}}  

Output:

The sum of first 100 numbers is: 5050

C++ program

#include <iostream> //for input output functions

using namespace std; //to identify objects like cin cout

int main(){     //start of main() function body

int cur_num   = 1; // stores numbers

int stop_num= 100; // stops at this number which is 100

int total = 0;//stores the sum of 100 numbers

/* loop takes numbers one by one from cur_num variable and continues to add them until the stop_num that is 100 is reached*/

while (cur_num <= stop_num) {  

//keeps adding the numbers from 1 to 100

//increments value of cur_num by 1 at each iteration

 total += cur_num;

 cur_num = cur_num + 1; }  

//displays the sum of first 100 numbers

cout<<"The sum of first 100 numbers is: "<<total;}

The output is given in the attached screen shot.

nope i prefer two because it is simpler, i don't like all the powers you get

explanation:

but that's my opinion

professionals can use many types of technology that can them. some examples are, computers (they research and can use for programs for data, they are also used for job applications, school work, and even to make new ideas), speedometers (can get data for unknown data), sometimes something as small as a pen (used for rough drafts, to insert data, and again job applications).
