hi friends
i just tried to change some part of this code and i just wanna make it a public code
i mean i wanna change int main () and ask the operator to insert the expression and then the program calculate it and return the result.
for example in a code that i had for addition of two numbers my int main () was like this
int main ()
{
int number1, number2;
string a,b;
cout > a;
cout > b;
cout
This task is not elementary. A program from the "syntax analyzer" class should be created. It analyzes the string, recognizes user identifiers, numbers and mathematical operations, and creates the syntax tree of the mathematical expression. Then, a dialog can be generated in which the user enters the values of the identifiers. The last stage is a calculation of the expression.
Thanks dear aparna but i need a calculator that calculate + - × ÷
In your calculator i can not calculate an expression like 25/5 + 3×2
