My program asks for a user to input integer values. Is there a way, just in case a user inputs a real number with decimal places, to make the program check if it is a real number or an integer value? The numbers MUST be integer values otherwise it will mess up the program. |

the function strintok(String):Boolean will tell you if it can be converted to an integer. |

So, as DtY implied, you should get the input as a string and then use strintok (input), strint (input), strrealok (input), and strreal (input) to convert the variable to the appropriate type. |

Oh yah, I should have mentioned you need to get input as a string. Thanks |
