code will not space my sentences

Question

hey, my code works but when I type in a sentence there aren't any spaces between. can someone tell me what I need to do to fix it?
Thank you!

#include <cs50.h>
#include <stdio.h>
#include <string.h>
#include <ctype.h>
#include <stdlib.h>

int main(int argc, string argv[])
{
if (argc != 2)
{
printf("Usage: ./caesar key\n");
return 1;
}

int k = atoi(argv[1]);
do
{
string p = get_string("plaintext: ");
for (int i = 0, n = strlen(p); i < n; i++)
{
if (islower(p[i]))
{
printf("%c", (((p[i] + k) - 97) % 26) + 97);
}
else if (isupper(p[i]))
{
printf("%c", (((p[i] + k) - 65) % 26) + 65);
}

}
printf("\n");
return 1;
}
while (argc == 2);

}

Answer 1

Assuming get_string supports space separated strings.
Just add another else if that tests if p[i] is a space and then print a space?
