Problem with strings.

Hi all, my name is attreme and I'm learning to program as an aeronautical engineer.
This was supposed to be a simple program that would read four strings and then print only the ones that started witht the letter "b." When I run the program, I don't get any error messages, but the program immediatly exits with 0. I believe that my problem is in the string "si." I wanted it to change the string from s1 to s2 and so forth, but I think it's just not reading. Please help.

Code:

---

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

int main() {
    char s1[5] = "abcd", s2[5] = "bcde", s3[5] = "bdef", s4[5] = "defg";
    int i;
    char sj[5] = "aaaa";
    char si[5];
    for (i = 0; i <=4; i++){
        strcpy (sj, si);
        if ((strncmp (sj, s2, 1)) == 0){
            printf ("%s", sj);
        }
    }
    return 0;
}

Thanks all.

Try This

Code:

---

#include<stdio.h>


int main() {
    char s[5][5] = {"abcd","bcde","bdef","defg","bact"};
    int i;
    for (i = 0; i <=4; i++)
        {
   
        if (s[i][0]=='b')
                {
            printf ("\n%s", s[i]);
        }
    }
    return 0;
}

Using strings within an array instead so that I could call each one by one instead of individual strings...hadn't thought of that.
Thank you very much.
