How to convert infix to postfix using stack of data structures

[Avisek Dewan]

i need a c program to convert infix to postfix using stack of data structures

[weaknessforcats]

For infix, pop the struct, pop the amount to add to the struct. Add the amoun top the struct.

For postfix, do the same except save the original pop and push the result back onto the stack. After you use the saved value, pop the stack to replace the saved value.
