Question

Write a C program that meets the following requirements.

Uses a while loop to display the first 10 natural numbers (on one row, with a tab separating each number)

Uses a while loop to find the sum of the second set of 10 natural numbers.

Reads a user entry and displays all the natural numbers up to the user entry (on a column list with a new line separating each number).

Finds and displays the sum of all natural numbers up to the user entry (same user entry as above).

Uses a while loop to calculate and display the cube of the number entered (same user entry as above). Uses a while loop to display a multiplication table from one to ten of the number entered (same user entry as above).

Uses a while loop to display the user-entry-number of asterisks (each separated by a tab).

Uses a while loop to prompt the user for 10 additional integer values.

Calculates and displays the sum of the 10 integers entered on the previous step.

Calculates and displays the average of the 10 integers entered on the previous step.

int main()
{
    int i=1,j=11,temp;
    float avg,float_sum;
    int sum,input;
    //First Ten Natural Numbers
    printf("First Ten Natural Numbers:\n");
    while(i<=10)
    {
        printf("%d\t",i);
        i++;

    printf("\nSum of second set of 10 Natural Numbers: %d",sum);

    float_sum = sum;
    avg = float_sum/10;
    //PRINTING AVERAGE OF INTEGERS
    printf("\n Average of 10 integers Entered: %.4f\n",avg);
