Storing an integer into a char* in C++

Question

I'm writing some code that returns an integer, which then needs to be outputted using printw from the ncurses library. However, since printw only takes char*, I can't figure out how to output it.

Essentially, is there a way to store a integer into a char array, or output an integer using printw?

Answer 1

Use itoa() or sprintf() to convert integer to ascii string.

Example:

char s[50];
sprintf(s, "%d", someInteger);

now u can pass s as char*

Answer 2

itoa will help you.

Answer 3

The itoa function converts an int to char*.

Answer 4

printw() accepts const char * as a format specifier. What you want is

printw("%d",yournumber);

Answer 5

std::stringstream
