Thread: wgiven a person’s name, prints a person’s initials

Oh totally sorry about that. I didn't even need to be using that anyway. I rewrote the program from scratch. Here is the new code.

Code:

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


int main(void)
{
    // Prompt the user to type their full name.
    printf("What is your full name? ");
    string s = get_string();
    
    // Checks if the string is not NULL.
    if (s != NULL)
    
    {   
        // Iterate over the characters one at a time.
        for (int i = 0, n = strlen(s); i < n; i++)
        {
            // Checks to see if s[i] is a space character.
            if (s[i] == " ")
                
                // Prints the first letter, and the letters after the space character.
                printf("%c%c%c", s[0], s[i+1], s[i+1]);
 
        }
        
        
          
    }
    
    printf("\n");


    return 0;
}

I'm getting an error when I try to run it though.
