Function to check operators...

Hi,

I want to write a function which takes two operators as characters and check if one has a higher, lower or equal precendece than the other. Operators are only going to be + * / -. I thought of one way: assign numbers to the operatos, number one to plus and numbers 2 to * and /. Then check if one is greater than the other. Can anyone think of some other way?

If that is all the program does, then ur approach is fine.

You cud simply put all the operator chars in a char array...

char a[]={'*','/','+','-',......}

Have some schema as above that 0,1 elements have same precedence, 2,3 have same, etc.etc.

Now find out the difference in indices of the inputted chars(ops), and display result based on that. :)

Another appraoch..

char a[]={'*','/',' ' (BLANK), '+','-'....}

Separate all "levels" of precedence by a BLANK. Now just find out whether u traversed through a ' ' between the positions of the two ops in the array. If u did, then display "op 1 is higher", otherwise display "both have same precdence". :)

Yep thnx
