Answer:
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.
