To solve this problem, we need to swap the alternate digits of the given input number.

Here are the steps to achieve this:

1. Read the input number from the user.
2. Convert the input number to a string for easier manipulation.
3. Initialize an empty string to store the swapped digits.
4. Iterate through the characters of the input string using a loop.
5. Check if the current index is even or odd.
6. If the index is even, append the next digit to the swapped string.
7. If the index is odd, append the current digit to the swapped string.
8. Continue this process until all the digits have been processed.
9. Convert the swapped string back to an integer.
10. Print the final swapped number as the output.

Here is the code in C to implement the above steps:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main() {
    int input;
    printf("Enter the input number: ");
    scanf("%d", &input);

    // Convert input to string
    char inputString[20];
    sprintf(inputString, "%d", input);

    // Initialize swapped string
    char swappedString[20] = "";

    // Swap alternate digits
    int length = strlen(inputString);
    for (int i = 0; i < length; i++) {
        if (i % 2 == 0) {
            // Append next digit
            swappedString[i] = inputString[i + 1];
        } else {
            // Append current digit
            swappedString[i] = inputString[i - 1];
        }
    }

    // Convert swapped string to integer
    int swappedNumber = atoi(swappedString);

    // Print the swapped number
    printf("Swapped number: %d\n", swappedNumber);

    return 0;
}

This code takes an input number from the user, swaps the alternate digits, and prints the swapped number as the output.
