Program to Replace the Spaces of a String with a Specific Character

Program to replace the spaces of a string with a specific character

Explanation

In this program, we need to replace all the spaces present in the string with a specific character.

String: Once in a blue moon
String after replacing space with '-': Once-in-a-blue-moon 

One of the approach to accomplish this is by iterating through the string to find spaces. If spaces are present, then assign specific character in that index. Other approach is to use a built-in function replace function to replace space with a specific character.

Algorithm

Define a string.
Determine the character 'ch' through which spaces need to be replaced.
Use replace function to replace space with 'ch' character.

Solution

Python

string = "Once in a blue moon";
ch = '-';
 
#Replace space with specific character ch
string = string.replace(' ', ch);
 
print("String after replacing spaces with given character: ");
print(string);

Output:

String after replacing spaces with given character: 
Once-in-a-blue-moon

C

#include <stdio.h>
#include <string.h>
 
int main()
{
    char string[] = "Once in a blue moon";
    char ch = '-';
    
    //Replace space with specific character ch
    for(int i = 0; i < strlen(string); i++){
        if(string[i] == ' ')
            string[i] = ch;
    }
    
    printf("String after replacing spaces with given character: \n");
    printf("%s", string);
        
    return 0;
}

Output:

String after replacing spaces with given character: 
Once-in-a-blue-moon

JAVA

public class ReplaceSpace
{
    public static void main(String[] args) {
        String string = "Once in a blue moon";
        char ch = '-';
        
        //Replace space with specific character ch
        string = string.replace(' ', ch);
        
        System.out.println("String after replacing spaces with given character: ");
        System.out.println(string);
    }
}

Output:

String after replacing spaces with given character: 
Once-in-a-blue-moon

C#

using System;
                    
public class ReplaceSpace
{    
    public static void Main()
    {
        String string1 = "Once in a blue moon";
        char ch = '-';
        
        //Replace space with specific character ch
        string1 = string1.Replace(' ', ch);
        
        Console.WriteLine("String after replacing spaces with given character: ");
        Console.WriteLine(string1);
    }
}

Output:

String after replacing spaces with given character: 
Once-in-a-blue-moon

PHP

<!DOCTYPE html>
<html>
<body>
<?php
$string = "Once in a blue moon";
$ch = '-';
 
//Replace space with specific character ch
$string = str_replace(' ', $ch, $string);
 
print("String after replacing spaces with given character: <br>");
print($string);
?>
</body>
</html>

Output:

String after replacing spaces with given character: 
Once-in-a-blue-moon
