EDIT: As pointed out in the comment, itoa() is not a standard, so better use sprintf() approach suggested in the rivaling answer! You can use itoa() function to convert your integer value to a string. Here is an example: If you want to output your structure into a file there is no need to convert any value beforehand. You can just use … Read more
Python 3 In Python 3, this question doesn’t apply. The plain int type is unbounded. However, you might actually be looking for information about the current interpreter’s word size, which will be the same as the machine’s word size in most cases. That information is still available in Python 3 as sys.maxsize, which is the maximum value representable by … Read more
For reference—future Python possibilities:Starting with Python 2.6 you can express binary literals using the prefix 0b or 0B: You can also use the new bin function to get the binary representation of a number: Development version of the documentation: What’s New in Python 2.6
Am I correct to say the difference between a signed and unsigned integer is: Unsigned can hold a larger positive value and no negative value. Unsigned uses the leading bit as a part of the value, while the signed version uses the left-most-bit to identify if the number is positive or negative. Signed integers can … Read more
How do I generate a random int value in a specific range? I have tried the following, but those do not work: Attempt 1: Bug: randomNum can be bigger than maximum. Attempt 2: Bug: randomNum can be smaller than minimum.
In C++11 you can use std::to_string: If you’re working with prior to C++11, you could use C++ streams: Taken from http://notfaq.wordpress.com/2006/08/30/c-convert-int-to-string/

I thought this would be really simple, but it’s presenting some difficulties. If I have How do I combine them to get a single string “John21”?
The java.lang.Character.getNumericValue(char ch) returns the int value that the specified Unicode character represents. For example, the character ‘\u216C’ (the roman numeral fifty) will return an int with a value of 50. The letters A-Z in their uppercase (‘\u0041’ through ‘\u005A’), lowercase (‘\u0061’ through ‘\u007A’), and full width variant (‘\uFF21’ through ‘\uFF3A’ and ‘\uFF41’ through ‘\uFF5A’) forms have numeric values from 10 through 35. This is … Read more
In C, the language itself does not determine the representation of certain datatypes. It can vary from machine to machine, on embedded systems the int can be 16 bit wide, though usually it is 32 bit. The only requirement is that short int <= int <= long int by size. Also, there is a recommendation that int should represent the native capacity of the processor. All types … Read more
