Question

Write a function oneSpaceAfterPeriod( String Parameter ) that will return a string with one space after every period. Another function twoSpaceAfterPeriod (String Parameter) that will return a string with two spaces after every period.

Answer 1

ONE SPACE METHOD

//method to provide one space after period symbol
string oneSpaceAfterPeriod(string s)
{
    int i,j=0;
    char s1[s.size()+1]; //allocate memory for a character array according to size of s
    for(i=0;i<s.length();i++)
    {
        if(s[i]=='.') //if period symbol found
        {
            s1[j]='.'; //copy the period symbol to converted string
            j++; //j is used for the index of converted string
            s1[j]=' '; //assign a white space to the string
            j++;
           }
           else
           { //copy all charcters except period symbol
               s1[j]=s[i];
               j++;
           }
             
   }
   s1[j]='\0'; //assign null to end
     
   return s1; //return converted string
}

TWO SPACE METHOD

//method to provide two white spaces after period symbol
string twoSpaceAfterPeriod(string s)
{
    int i,j=0;
    char s1[s.size()+1];
    for(i=0;i<s.length();i++)
    {
        if(s[i]=='.')//if period symbol found
        {
            s1[j]='.'; //copy the period symbol to converted string
            j++;//j is used for the index of converted string
            s1[j]=' '; //assign a white space after period symbol
            j++;
            s1[j]=' ';//assign second white space
            j++;
           }
           else//copy all charcters except period symbol
           {
               s1[j]=s[i];
               j++;
           }
             
   }
   s1[j]='\0'; //assign null to end
     
   return s1; //return converted string
}
