Example 1: char to int c++
int x = (int)character - 48;
Example 2: integer to char c++
// for example you have such integer int i = 3; // and you want to convert it to a char so that char c = '3'; what you need to do is, by adding i to '0'. The reason why it works is because '0' actually means an integer value of 48. '1'..'9' means 49..57. This is a simple addition to find out corresponding character for an single decimal digit integer: i.e. char c = '0' + i; If you know how to convert a single decimal digit int to char, whats left is how you can extract individual digit from a more-than-one-decimal-digit integer it is simply a simple math by making use of / and % int i = 123 % 10; // give u last digit, which is 3 int j = 123 / 10; // give remove the last digit, which is 12 The logic left is the homework you need to do then.
Example 3: C++ int to char*
std::string s = std::to_string(number); char const *pchar = s.c_str(); //use char const* as target type
