Problems
By inputting an integer operation formula and calling a function for the operation,
Write a program that outputs the results of the four basic operations (+ - * /). (For '/', output only the integer portion, and set the results of operations other than the four basic operations to 0.) (Write using an if_else statement.)
Example
10 + 20
10 + 20 = 30
