C Program to convert a number to a string

In this section we will see how to convert a number (integer or float or any other numeric type data) 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 42.26 Output: This program will return the string equivalent result of that number like "42.26"

Algorithm

Step 1: Take a number from the user Step 2: Create an empty string buffer to store result Step 3: Use sprintf() to convert number to string Step 4: End

Example Code

 Live Demo

#include<stdio.h> main() {    char str[20]; //create an empty string to store number    float number;    printf("Enter a number: ");    scanf("%f", &number); sprintf(str, "%f", number); //make the number into string using sprintf function printf("
You have entered: %s", str); }

Output:

Enter a number: 46.3258 You have entered: 46.325802
