operating symbols

[corbett]

how to ask the user to input operating symbols like "+","-","*" and then use it to operate on the numbers. The user should be asked to input the symbols not like this
1.+
2.-
3.*

[Dy7SLyTq]

input into a char and run a switch on it. depending on the symbol perform the operation. ie:
[code]
case '+':
lvalue += rvalue;
break;

[Ahmad1797]

there are plenty of ways

1) Use ASCII table and get values for algebraic symbols.

2) As DTSCode suggested you can use direct 'char' data type.
