Hope it helps! :)

Answer 2

itoa () function in C language converts int data type to string data type. Syntax for this function is given below.

char *  itoa ( int value, char * str, int base );

“stdlib.h” header file supports all the type casting functions in C language. But, it is a non standard function.
