Program to Remove Spaces from String

As we all know the String is a collection of character data types. In strings, only one variable is declared which can store multiple values. First, we will take the input string from the user. Then we will remove the spaces from the string using the while loop.

With the help of this program, we can Remove Spaces from String.

Algorithm:-

1. Declare the variables for the program. 

2. Take the input string from the user. 

3. Remove the spaces from the string. 

4. Print the output. 

5. End the program.

5. End the program.

Program to Remove Spaces from String:-

#include<stdio.h>
int main()
{
    //Declaring the variables for the program
    char str[50];
    int i=0, j, chk;
    /* 
    str=it will store the string input value
    i=it will store the integer value
    j=it will store the integer value
    chk=it will store the integer value
    */
    /* Taking the input string from the user */
    printf("Enter a String: ");
    gets(str);
    /* removing the spaces from the string */
    while(str[i]!='\0')
    {
        chk=0;
        if(str[i]==' ')
        {
            j=i;
            while(str[j-1]!='\0')
            {
                str[j] = str[j+1];
                j++;
            }
            chk = 1;
        }
        if(chk==0)
            i++;
    }
    /* printing the string value without spaces */
    printf("\nString (without spaces): %s", str);

    return 0;
}

#include<stdio.h>

int main()

{

//Declaring the variables for the program

char str[50];

int i=0, j, chk;

str=it will store the string input value

i=it will store the integer value

j=it will store the integer value

chk=it will store the integer value

/* Taking the input string from the user */

printf("Enter a String: ");

gets(str);

/* removing the spaces from the string */

while(str[i]!='\0')

{

chk=0;

if(str[i]==' ')

{

j=i;

while(str[j-1]!='\0')

{

str[j] = str[j+1];

j++;

}

chk = 1;

}

if(chk==0)

i++;

}

/* printing the string value without spaces */

printf("\nString (without spaces): %s", str);

return 0;

}

Output:-

In the above program, we have first initialized the required variable.

str[50] = it will hold the string value.

i = it will hold the integer value.
j = it will hold the integer value.
chk = it will hold the integer value.

Taking the input string from the user.

Removing the blank spaces from the string.

Printing the output.
