[nobantahir]

you're saving me from a professor who can't teach so I'm gonna watch all the ads I need to I love you

[aj-sknf]

in less than 6 minutes you taught me more about C and strings in C than i ever learned in a full semester on C programming. thank you, @EngineerMan!!

[nahoooj]

Thank you! Easy to understand as a beginner and straight to the point

[remotetechie]

Amazing content, great explanations. I love those short but really good comments for every code line!

[mikobrown]

Incredible, short and easy to understand. Thank you!

[shailendrakunwar]

Very precise an informative video .Thank you for uploading and hoping to see further more videos like this.

[devinramsden]

Great vids for brushing up on c before some classes, much love brother

[Mike-gseo]

Great explanation. Would appreciate something on structs if possible, in particular use of the flexible array member (unsized last element in struct). thanks

[QmVuamFtaW]

you explained more about strings in 6 minutes than my teacher did in the whole semester...

[soundsgood]

Dude this is so trippy coming from Java, thank you!

[EchoVidsu]

Best explanation so far on c strings. Thanks

[bishtss]

Nice content full of information. Thanks clearing the doubts.

[bigfella]

Engineer bro I want to thank you so much you need to teach I mean that! I had 2 eureka moments watch this video!

[chantelleboutin]

Succinct and to the point. Very educational.

Here's a challenge, using Git to control a solo project from multiple computers. Git still seems nebulous and complex. Maybe you can show us how with no time a wasting.

[pwlegolas]

thank you engineer man... Your videos help a lot !

To print integer arrays, we would normally need a loop and some variable to move through the indices, one after the other.
But why isn't this the case with character arrays? Why do we just type the array variable name and everything works fine?

[kelechistewart]

Thanks for another helpful video! Could you possibly do one on creating different structures in C, for example a Binary Tree?

[RussTeeTrombone]

Awesome and succinct. Thanks a ton for these.

Hi Engineer Man! Thank you for posting this video and welcome to YouTube! In your intro video you said that you like video request so here is one for you... I am trying to create a program in C to load a tab delimited text file, from any folder on my computer(in the future to be input from the user), print the text (strings, I believe) from the text document to the screen, then sort the information based upon a certain column, reprint it to the screen, and then finally save it to a new text file. Can you help me, and everyone else, by showing me how I might go about doing this? This is not for hw/class, it is a personal project.

Here is what I have so far:

#include <stdio.h>
#include <string.h>
#define N 30
int main()
{
char name[];
char course[];
FILE *pointer = fopen("C:\\Users\\Jesse Hight\\Desktop
\\TutoringCodeFolder\SimplifiedStudentRequests", "r");
test=fscanf(pointer, "%s, %s", &name[N], &course[N]);

printf("%s\t%s", name[ ], course[ ]);
fclose(f);

/*
Idea:
row 1 of array 1 (from the original file)=row 1 of array2.
search array 1 for a course equal to row 1 of array 2.
for( )
if(array1[i][2]==array2[1][3]
array2[k][L]=array1[i][2]
k++
L=3
else
search array1 for new subject not equal to current/last row of array2
new subject from array1=next row of array2
*/

}


The original text file looks like:

Jesse ES 330-01
John MA 330-01
Alexa MA 330-01
Jose FN 361-01
Dave FN 361-01
Gabriel ES 330-01
Steve FN 361-01
Parker FN 361-01
Robert FN 361-01
Caroline ES 330-01


And I would like the output to be like this, with the list sorted by common classes:

Jesse ES 330-01
Caroline ES 330-01
Gabriel ES 330-01
John MA 330-01
Alexa MA 330-01
Jose FN 361-01
Dave FN 361-01
Steve FN 361-01
Parker FN 361-01
Robert FN 361-01


Thank you!

Isn't the NULL byte '/0' the same as 0 or zero? I have successfully used a plain zero to terminate strings in C. Is that just a compiler specific (Boreland 4.5) exception?
