Hi,
I am new to programming.
I am trying to do the foolowing program.
I am using Stack class to calculate simple arithmetic expressions involving integers,
such as 1+2*3.your program would execute operations in the order given,without regarding to the precedence of operators.
*Thus, the expression 1+2*3 should be calculated (1+2)*3=9,not 1+(2*3)=7.
If i get the input as 1+2*3,i know how to convert the
string 1,2,3 to Integer.but i don't know how to covert +,* from string type to operator.
Please help me to find out.
