Write a program using C language that sorts the 10 rollno,s of your class placed in an array of size 10?Input:87109132546 Output:12345678910

Here’s a simple C program that sorts the roll numbers stored in an array of size 10. The program uses the bubble sort algorithm for sorting the roll numbers.

C Program to Sort Roll Numbers

#include <stdio.h>

int main() {
    int rollno[10], i, j, temp;

    // Input 10 roll numbers
    printf("Enter 10 roll numbers: ");
    for(i = 0; i < 10; i++) {
        scanf("%d", &rollno[i]);
    }

    // Bubble sort algorithm
    for(i = 0; i < 10 - 1; i++) {
        for(j = 0; j < 10 - i - 1; j++) {
            if(rollno[j] > rollno[j + 1]) {
                // Swap
                temp = rollno[j];
                rollno[j] = rollno[j + 1];
                rollno[j + 1] = temp;
            }
        }
    }

    // Output sorted roll numbers
    printf("Sorted roll numbers: ");
    for(i = 0; i < 10; i++) {
        printf("%d ", rollno[i]);
    }
    
    return 0;
}

How the Program Works

1. Input: The program prompts the user to enter 10 roll numbers which are stored in an array.
2. Sorting: The program implements the bubble sort algorithm to sort the roll numbers in ascending order.
3. Output: Finally, it prints the sorted roll numbers.

Final Answer

Use the above code to sort roll numbers. Input: 8710913254 will yield Output: 1 2 3 4 5 7 8 9 10.
