GCC Compiler Error on Binary operands

[Shantanu Godbole]

temp1[i] = number%pow(10,i )/pow(10,i-1);

An error is shown in this line even though i include math.h library and use the correct operators

ERROR: invalid binary operands to %
How to deal with it?

[arnaudk]

The operands of % must be of type int. Are you sure they're integers? For one, pow() returns a double....

[donbock]

temp1[i] = number%pow(10,i )/pow(10,i-1);

You have two operations (% and /). What order do you want them to occur in? Don't spend 5 minutes looking up the C order-of-operations rules; spend 30 seconds adding parentheses.

I'm going to a guess: you're seeking to solve
temp1[i] = number % (pow(10,i)/pow(10,i-1));
[arnaudk is write: this expression is still illegal because of non-int argument.]

Write that out with pencil and paper as an arithmetic problem rather than as a coding problem. Look for ways to simplify the expression.

[weaknessforcats]

temp1[i] = number%pow(10,i )/pow(10,i-1);

If you are trying to conver an integer to a string, this is not how you do it.

To get the value of a decimal position, do this:

(theInteger / value) %10 + '0'

where value is 100 or 1000 etc. The '0' converts the integer result to an ASCII character between 0 and 9 and it's that that goes in the string.
