Write a program in which the driver simply calls a function

Resolved Question:

Write a program in which the driver simply calls a function
named inToPostfix which reads an infix expression from
standard input and writes the equivalent postfix expression
to standard output. The infix expression includes operands,
parentheses, and operators, where the operands are single
lowercase characters, and the operators are +, -, *, /, and
^ (exponentiation).

Use the STL container stack to store a stack of characters.
Include error checks in the code.

Your program should be implemented in a single file.

I am using Putty and when I tried to compile it, I got these errors.



infix_to_postfix.cpp: In function ‘int main()’:
infix_to_postfix.cpp:12:17: error: ‘system’ was not declared in this scope
infix_to_postfix.cpp: In function ‘void infix_to_postfix()’:
infix_to_postfix.cpp:30:22: warning: converting to non-pointer type ‘char’ from NULL [-Wconversion-null]
infix_to_postfix.cpp:31:20: warning: converting to non-pointer type ‘char’ from NULL [-Wconversion-null]

Expert:  LogicPro replied 9 months ago.
I am using Windows and it is working fine here.
Remove the line system("pause") from code and then let me know.
Customer: replied 9 months ago.

I'm still getting these errors now.


 


infix_to_postfix.cpp:29:22: warning: converting to non-pointer type ‘char’ from NULL [-Wconversion-null]
infix_to_postfix.cpp:30:20: warning: converting to non-pointer type ‘char’ from NULL [-Wconversion-null]

Expert:  LogicPro replied 9 months ago.
these are only warnings.
Try to run your program. It should run now.
Customer: replied 9 months ago.

It's working well. But I was wondering if you could explain this part so I can understand what's going on:


char Symbol [5] = {NULL};


char Temp [5] = {NULL};
