## C Program to Find the Runner-Up Score: Explained Step by Step

### What is a Runner-Up Score?

Before we dive into the details of the program, let’s clarify what a runner-up score means. In a list of numbers, the runner-up score is the second-highest value.

For example, if we have a list [5, 7, 2, 9, 3], the runner-up score would be 7 since it is the second-highest value in the list.

### Algorithmic Approach to Finding the Runner-Up Score

To find the runner-up score in a given list, we can follow a simple algorithmic approach:

1. Initialize two variables, `max` and `runnerUp`, to the smallest possible value.
2. Iterate through each element in the list.
3. Compare the current element with the `max` variable.
4. If the current element is greater than `max`, update both `max` and `runnerUp` accordingly.
5. If the current element is less than `max` but greater than `runnerUp`, update `runnerUp` only.
6. Repeat steps 3-5 until all elements in the list are processed.
7. Finally, the value stored in `runnerUp` will be the runner-up score.

Let’s now write a C program to implement this algorithm.

## C Program to Find the Runner-Up Score

``````#include <stdio.h>

int findRunnerUp(int arr[], int size) {
int max = -9999; // Initialize max to a very small value
int runnerUp = -9999; // Initialize runnerUp to a very small value

for (int i = 0; i < size; i++) {
if (arr[i] > max) {
runnerUp = max;
max = arr[i];
} else if (arr[i] > runnerUp && arr[i] < max) {
runnerUp = arr[i];
}
}

return runnerUp;
}

int main() {
int scores[] = {5, 7, 2, 9, 3};
int size = sizeof(scores) / sizeof(scores[0]);

int runnerUp = findRunnerUp(scores, size);

printf("The runner-up score is: %d\n", runnerUp);

return 0;
}``````

The above C program takes an array of scores and finds the runner-up score using the algorithm we discussed earlier.

In this example, the runner-up score would be 7.

Q1: What is the purpose of finding the runner-up score?

Finding the runner-up score is useful in various scenarios, especially in sports competitions, where it is important to identify the second-best performer.

Q2: Can the runner-up score be the same as the highest score?

No, the runner-up score cannot be the same as the highest score. It must be the second-highest value in the list.

Q3: What if there are multiple occurrences of the highest value in the list?

In our algorithm, if there are multiple occurrences of the highest value, the runner-up score will be the next highest value.

Q4: Can this program handle large lists of scores?

Yes, the program can handle lists of any size. It iterates through the list once, making it efficient for large datasets.

Q5: Is the program compatible with other programming languages?

While this specific program is written in C, the algorithm can be implemented in other programming languages with some modifications.

Q6: Can I use this program for non-numeric data?

No, this program is designed to find the runner-up score in a list of numbers. It won’t work for non-numeric data.
