you noob. you're banned.

just kidding.

but seriously, you cant have a single array of floats "mixed with" ints.

they're all either one or the other. probably floats. some of the floats just happen to not have any fractional part.

i'm not sure i fully understand your question... you want to print them out exactly as entered? i guess theres a number of ways you could do this.

one way would be to input them as strings, and store them in a string array, then convert them to the appropriate value when needed. ... or, along those lines, a structure where you have the "as enetered" string element, along with a floating point "value" element

is this making sense? is this relevant to your question?

Yup, a string was what i thought, but i wondered if i could have an array of floats that i can print out as integers if they don't have fractional parts. and if i could print a float to the last digit, without zeros at the end, for example if the input is 1.6 i print 1.6, not 1.60000

well, you can use format specifiers

"%.3f" for instance will print up to 3 decimal places but only if they are non-zero digits.

"%.03f" will always print 3 decimal places even if they are zero digits.

You can have an array with different data types, you just need to point to them using void*

example:

void *array[] = {(int*)123, (char*)"Hello"};
cout << (int)array[0]; // prints 123
cout << (char*)array[1]; // prints "Hello"
commented: good call +3
