(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

Explanation:
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#define MAX_LIMIT 50
int checkComma(char *input)
{
int flag = 0;
for(int i = 0; i < strlen(input); i++)
{
if(input[i] == ',')
{
flag = 1;
break;
}
}
return flag;
}
int main(void)
{
char input[MAX_LIMIT];
char *words[2];
char delim[] = ", ";
printf("\n");
do
{
printf("Enter input string: ");
fgets(input, MAX_LIMIT, stdin);
size_t ln = strlen(input) - 1;
if (*input && input[ln] == '\n')
input[ln] = '\0';
if(strcmp(input, "q") == 0)
{
printf("Thank you...Exiting\n\n");
exit(1);
}
else
{
if(checkComma(input) == 0)
{
printf("No comma in string.\n\n");
}
else
{
char *ptr = strtok(input, delim);
int count = 0;
while(ptr != NULL)
{
words[count++] = ptr;
ptr = strtok(NULL, delim);
}
printf("First word: %s\n", words[0]);
printf("Second word: %s\n\n", words[1]);
}
}
}while(strcmp(input, "q") != 0);
return 0;
}

chars2string(in1, in2)
if __name__ == '__main__':
main()
Explanation:
The programming language used is python 3.
The script first defines a function getChar and makes use of a while loop in combination with try and except blocks and IF statements, the code ensures that both inputs that are entered by the user after the prompt are 1 in length. i.e. Just one character. This function returns the two characters that were entered.
The second function that is defined is chars2string this function takes two arguments, It repeats each argument five times and returns a joined string.
Finally, the main function is defined and it calls the getChar function first, the values that are returned by this function is assigned to two variables, that is then passed on to the chars2string function. The main function is called and the Joined string is printed to the screen.
