Practical C Programming

How to do it…

1. Enter a number to assign to the n variable:

printf("Enter a number ");scanf("%d",&n);

2. Invoke the findarmstrong function. The value assigned to n will get passed to this function:

findarmstrong(n)

3. In the function, the passed argument, n, is assigned to the numb parameter. Execute a while loop to separate out all the digits in the numb parameter:

while(numb >0)

4. In the while loop, apply the mod 10 (%10) operator on the number assigned to the numb variable. The mod operator divides a number and returns the remainder:

remainder=numb%10;

5. Push the remainder to the stack:

push(remainder);

6. Remove the last digit of the number in the numb variable by dividing the numb variable by 10:

numb=numb/10;

7. Repeat steps 4 to 6 until ...
