Print sequence between two numbers and calculate its average

Write a C program that accepts a pair of numbers from the user and prints the sequence from the lowest to the highest number. Also, print the average value of the sequence.

Sample Solution:

C Code:

#include <stdio.h>

int main () {
    int p, x = 1, y = 1, i = 0, temp = 0;
    float sum_val = 0;

    // Prompt user for input
    printf("Input two pairs values (integer values):\n");

    // Read two integer values from user and store them in 'x' and 'y'
    scanf("%d %d", &x, &y);

    // Check if both 'x' and 'y' are positive
    if (x > 0 && y > 0) {
        // Swap 'x' and 'y' if 'y' is smaller than 'x'
        if (y < x) {
            temp = x;
            x = y;
            y = temp;
        }
        printf("\nSequence from the lowest to highest number:\n");

        // Loop to print and accumulate values from 'x' to 'y'
        for (p= 0, i = x; i <= y; i++) {
            sum_val += i; // Accumulate the values for average calculation
            printf("%d ", i);
            p++;
        }

        // Print the average value of the sequence
        printf("\nAverage value of the said sequence\n%9.2f", sum_val / p);
    }

    return 0; // End of program
}

Sample Output:

Input two pairs values (integer values):
14
25

Sequence from the lowest to highest number:
14 15 16 17 18 19 20 21 22 23 24 25
Average value of the said sequence
    19.50

Sample Output:

Input two pairs values (integer values):
35
13

Sequence from the lowest to highest number:
13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35
Average value of the said sequence
    24.00

• Write a C program to print all numbers between two limits and calculate their average using an iterative approach.
• Write a C program to store the sequence in an array, then compute and print the average using pointer arithmetic.
• Write a C program to use a function that both prints the sequence from min to max and returns the calculated average.
