Establish a sequential stack, and run operations in the sequential stack. General operations include：Create stack, push element into stack, pop element from the stack, display element in the stack, check if the stack is full. Implementation of algorithm Use stack to convert the decimal digit to octal digit. Define a function of conversion, create a stack, read N and push it into stack. Get the remainder of N%8 and push into stack. Go on the %8 until the remainder is 0. Pop the remainder and get the octal digit.
