Implement your own itoa() in C
In this section we will see how to convert an integer number to a string.
The logic is very simple. Here we will use the sprintf() function. This function is used to print some value or line into a string, but not in the console. This is the only difference between printf() and sprintf(). Here the first argument is the string buffer. where we want to save our data.
Input: User will put some numeric value say 42
Output: This program will return the string equivalent result of that number like “42”
Algorithm:
Step 1: Take a number as argument Step 2: Create an empty string buffer to store result Step 3: Use sprintf() to convert number to string Step 4: End
Example Code
#include<stdio.h>
char* my_itoa(int number) {
char str[20]; //create an empty string to store number
sprintf(str, "%d", number); //make the number into string using sprintf function
return str;
}
main() {
int number;
printf("Enter a number: ");
scanf("%d", &number);
printf("You have entered: %s", my_itoa(number));
}Output
Enter a number: 56 You have entered: 56
