Question

Assume the variable LIST is defined as a list of numbers. Write a code segment that utilizes a loop to total up all of the numbers in the list up to, but not including, the first negative number. Store the result in the variable TOTAL. % test cases % LIST = [ 1 4 6 -2 7 9]; TOTAL = 11; % LIST = [ -2 4 5 7 9]; TOTAL = 0; % your code segment here %----------------------- % set the variable TOTAL to be the sum of the all numbers in LIST up to the first negative number

Answer 1

Please find below, the required code for the program giving the sum of all numbers in a LIST, upto the first negative number.

NOTE: Nothing was described in the question regarding the coding language, so I have written the code in C++.

//start of code

#include <iostream>
using namespace std;

int main() {
   cout << "Enter the number of elements: ";
int length;
cin >> length;

int *LIST = new int[length];
  
for(int i=0; i<length;i++){
   cin>>LIST[i];
}
  
/*int LIST[6] = {1,4,6,-2,7,9}; //uncomment this, if static input is required and comment the above code
int length = 6; //and change the input data according to your need*/
int TOTAL=0;
for(int i=0;i<length;i++){ //loop through length of list to add each elements value to TOTAL
   if(LIST[i]<0){ //if value is less than zero, display total and exit the program
       cout<<"TOTAL = "<<TOTAL;
       return 0;
   }
   else{
       TOTAL = TOTAL + LIST[i]; //otherwise, add the element value to TOTAL
   }
}
cout<<"TOTAL = "<<TOTAL; //display TOTAL
   return 0;
}

//end of code

Hope this solves your problem, and if it does, please give this answer a thumbs up. Thank you.
