C program to calculate the sum of Numbers Until a Negative Value is Entered using break statement.

In this program, the goal is to continuously input numbers from the user and calculate their sum. The loop will keep adding the numbers until the user enters a negative number. As soon as a negative number is entered, the program will stop collecting input and print the total sum of all the entered positive numbers.

How it works:

• The program asks the user to enter numbers in a loop.
• It keeps adding the entered numbers to a variable sum.
• If the user enters a negative number, the loop ends using the break statement.
• The program then prints the total sum of all the non-negative numbers entered.

#include <stdio.h>

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

    // Infinite loop to keep asking for numbers
    while (1) {
        printf("Enter a number: ");
        scanf("%d", &num);

        // If the number is negative, break the loop
        if (num < 0) {
            break;
        }

        // Add the number to the sum
        sum += num;
    }

    // Print the total sum of the entered numbers
    printf("Sum of numbers: %d\n", sum);

    return 0;
}

Output -

Enter a number: 34
Enter a number: 67
Enter a number: 89
Enter a number: -90
Sum of numbers: 190
