For the given instructions you must use C language (DO NOT USE C++) Write a C program (not C++) to calculate and display the numeric result of a Postfix Arithmetic Expression. In the Postfix Notation, an arithmetic operator is placed after two operands, and parentheses are not used. EXAMPLE : Infix notation : (10 + 5)/2 + 6 - 10/2 Postfix notation : 10 5 + 2 / 6 + 10 2 / - Numeric result : 7.5 + 6 - 5 = 8.5 You should use the following method for calculating the numeric result of a postfix arithmetic expression: 1) In a loop, program asks user to enter the tokens in the POSTFIX arithmetic expression one-by-one. A token is a string defined as a char array. • Atoken can be either a float number operand (such as "152.43", "2.7", etc.), or it can be an arithmetic operator (such as "+", "-*, "*", "/" ). In order to finish the looping, user will enter the word "end" as the last token. There is no need to check the validity of the postfix arithmetic expression entered by user. 2) Whenever program reads an operand from keyboard, program pushes it onto a Stack as a float number. Program should convert the token string (operand) to a float number and then should push it onto the Stack.

For the given instructions you must use C language (DO NOT USE C++) Write a C program (not C++) to calculate and display the numeric result of a Postfix Arithmetic Expression. In the Postfix Notation, an arithmetic operator is placed after two operands, and parentheses are not used. EXAMPLE : : (10 + 5)/2 + 6- 10/2 Postfix notation : 10 5 + 2 / 6 + 10 2 / - Numeric result : 7.5 + 6 - 5 = 8.5 Infix notation You should use the following method for calculating the numeric result of a postfix arithmetic expression: 1) In a loop, program asks user to enter the tokens in the POSTFIX arithmetic expression one-by-one. • A token is a string defined as a char array. • A token can be either a float number operand (such as "152.43", "2.7", etc.), or it can be an arithmetic operator (such as "+", " -", "*", "/" ). • In order to finish the looping, user will enter the word "end" as the last token. There is no need to check the validity of the postfix arithmetic expression entered by user. 2) Whenever program reads an operand from keyboard, program pushes it onto a Stack as a float number. Program should convert the token string (operand) to a float number and then should push it onto the Stack. You should use the array-implemented Stack that can be found in the lecture slides, but you should not use the built in C++ STL stack class. 3) Whenever program reads an arithmetic operator from keyboard, program pops two operands from the Stack. Then program applies the arithmetic operation on those two operands, and pushes the intermediate result onto the Stack. 4) Looping finishes when all tokens are processed. Then program displays the final calculated numeric result on the screen.

EXAMPLE SCREEN OUTPUT To finish, enter the word "end". TEMPLATE CODE (YOU MUST USE) #include <stdio.h> Enter a token : 10 #include <stdlib.h> Enter a token : 5 #include <string.h> Enter a token : + Enter a token : 2 int main() { Enter a token : / Enter a token : 6 ...... Enter a token : + // You must use a float type variable named as // 'result' to print your output to screen. float result; Enter a token : 10 Enter a token : 2 Enter a token : / printf("Result is : %.2f \n", result); return e; Enter a token : - Enter a token : end } Result is : 8.50
