Question

Write a C program named space_to_line.c that features a while loop that continuously reads input from the user one character at a time and then prints that character out. The exception is that if the user inputs a space character (‘ ‘), then a newline character (‘\n’) should be printed instead. This will format the output such that every word the user inputs is on its own line. Other than changing the spaces to newlines, the output should exactly match what the user inputs. If the user inputs a period character (‘.’) then the loop should break and the program should terminate. You should also print a single newline character after the loop breaks, but before the program exits. This just ensures that the shell prompt will be on a new line after the program finishes. For this problem, you should use getchar() to read input and putchar() to print input.

Answer 1

#include <stdio.h>
#include <conio.h>
int main()
{
char c;
while(1) {
c = getchar();
if (c == '.'){ //Break the loop if user enters '.'
break;
}
else if(c == ' ') { //Check if user entered space, print '\n' instead of space
putchar('\n');
}
else {
putchar(c);
}
}
putchar('\n'); // Single newline character before exiting the program
return 0;
}
