C program to convert a number to string

In this section, we will learn how to convert a number (integer or floating point or any other numeric type data) into a string.

The logic is very simple. Here we will use sprintf() function. This function is used to print certain values ​​or lines into a string but not in the console. This is the only difference between printf() and sprintf(). The first parameter here is the string buffer. Where we want to save the 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

Sample code

Real-time demonstration

#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("</p><p>You have entered: %s", str);
}

Output:

Enter a number: 46.3258
You have entered: 46.325802
