C itoa () function:
- 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.
Example program for C itoa () function:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
#include <stdio.h> #include <stdlib.h> #include <string.h> int main() { int a=54325; char buffer[20]; itoa(a,buffer,2); // here 2 means binary printf("Binary value = %s\n", buffer); itoa(a,buffer,10); // here 10 means decimal printf("Decimal value = %s\n", buffer); itoa(a,buffer,16); // here 16 means Hexadecimal printf("Hexadecimal value = %s\n", buffer); return 0; } |
itoa () function Output:
|
Binary value = 1101010000110101
Decimal value = 54325
Hexadecimal value = D435
