In C Please

*Asked before but all previous answers do not work correctly*

10.6 LAB: Warm up: Parsing strings

(1) Prompt the user for a string that contains two strings separated by a comma. (1 pt)

• Examples of strings that can be accepted:
  • Jill, Allen
  • Jill , Allen
  • Jill,Allen

Ex:

Enter input string: Jill, Allen

(2) Report an error if the input string does not contain a comma. Continue to prompt until a valid string is entered. Note: If the input contains a comma, then assume that the input also contains two strings. (2 pts)

Ex:

Enter input string: Jill Allen Error: No comma in string. Enter input string: Jill, Allen

(3) Extract the two words from the input string and remove any spaces. Store the strings in two separate variables and output the strings. (2 pts)

Ex:

Enter input string: Jill, Allen First word: Jill Second word: Allen

(4) Using a loop, extend the program to handle multiple lines of input. Continue until the user enters q to quit. (2 pts)

Ex:

Enter input string: Jill, Allen First word: Jill Second word: Allen Enter input string: Golden , Monkey First word: Golden Second word: Monkey Enter input string: Washington,DC First word: Washington Second word: DC Enter input string: q

Code

#include <stdio.h>

#include<string.h>

int checkComma(char []);

#define MAX_SIZE 50

int main() {

char str[MAX_SIZE];

char firstWord[MAX_SIZE/2];

char secondWord[MAX_SIZE/2];

int commaPos,i,j;

while(true)

{

printf("Enter input string:\n");

scanf("%[^\n]%*c", str);

if(strcmp(str, "q")==0)

break;

commaPos=checkComma(str);

if(commaPos>0)

{

j=0;

for(i=0;i<commaPos;i++)

{

If(str[i]!=' ')

firstWord[j]=str[i];

j++;

}

firstWord[i]='\0';

j=0;

for(i=commaPos+1;i<str[i]!='\0';i++)

if(str[i]!=' ')

{

secondWord[j]=str[i];

j++;

}

secondWord[j]='\0';

printf("First word: %s\n",firstWord);

printf("Second word: %s\n",secondWord);

}

else

{

printf("Error: No comma in string.\n");

}

}

}

int checkComma(char str[])

{

int i=0;

for(i=0;str[i]!='\0';i++)

if(str[i]==',')

return i;

return -1;

}

output
