Write a program that removes all spaces from the given input.

Question

Write a program that removes all spaces from the given input.

Ex: If the input is:

Hello my name is John.

the output is:

HellomynameisJohn.

Your program must define and call the following function. The function should return a string representing the input string without spaces.

string RemoveSpaces(string userString)

#include <iostream>

using namespace std;

/* Define your function here */

int main() {

/* Type your code here. Your code must call the function. */

return 0;

}

I need help please

Answer 1

Hi you want skip all spaces.

for (int i = 0; str[i]; i++)

        if (str[i] != ' ')

            str[count++] = str[i];

Answer 2

using namespace std;

#include <iostream>

#include <string.h>

#include <stdlib.h>

#include <stdio.h>

#define BLANK_CHAR (' ')

int CountCharacters(char userChar, char * userString)

{

int countReturn=0;

int n = strlen(userString);

for (int iLoop=0; iLoop<n; iLoop++)

{

if (userString[iLoop]==userChar)

{

countReturn++;

}

}

return(countReturn);

}

/******************************************

Side Effects:

CALLER MUST FREE THE OUTPUT BUFFER that is returned

char * RemoveSpaces(char * userString)

{

{

int n = strlen(userString);

outbuff = (char *) malloc(n);

{

memset(outbuff,0,n);

int iIndex=0;

//copies non-blank chars to outbuff

for (int iLoop=0; iLoop<n; iLoop++)

{

if (userString[iLoop]!=BLANK_CHAR)

{

outbuff[iIndex]=userString[iLoop];

iIndex++;

}

} //for

}

}

return(outbuff);

}

int main()

{

char inbuff[255];

cout << " PLEASE INPUT THE STRING OF WHICH YOU WOULD LIKE TO STRIP WHITESPACE CHARS :>";

gets(inbuff);

char * outbuff = RemoveSpaces(inbuff);

if (outbuff !=NULL)

{

cout << ">" << outbuff << "<" << endl;

free(outbuff);

}

memset(inbuff,0,255);
