This is C language.

Edit a new file p1.c. This will be the driver for the program and contains a main function. It enforces an old standard: ANSI.

Using a series of Push and Pop functions, simulate a postfix evaluation of the expression:5 9 8 + 4 6 * * 7 * +

Hint: Push the numerical values. Pop two operands when an operator is encountered. Push the result back on the stack.

p1.c:

/* * File: p1.c -- C driver for dynamic stack * * TODO: add your name, class, date (also add same to stackd.[ch] */ #include \"stackd.h\"

void show(stack s) { PrintStack(s); printf(\"--- \"); }

int main(void) { stack s; el_t e;

/* TODO: Demonstrate the operation of this postfix expression. * 5 9 8 + 4 6 * * 7 * + */

return 0; }
