#include <stdio.h>

int main() {
int num, sum = 0;

// Reading numbers until a negative number is encountered using a while loop and break
while (1) {
printf(“Enter a number (enter a negative number to stop): “);
scanf(“%d”, &num);

if (num < 0) {
break; // Exit the loop if a negative number is encountered
}

sum += num;
}
