Deelaw CS GO says:


int main()
int favorite ;
printf(“If you like COD or Java then you are my best friendn”);
scanf(” %d” , &favorite);

if ((favorite == ‘COD’) || (favorite == ‘Java’)){
printf(“You are my best friend”);
printf(“We are enemies”);
return 0 ;

This code never runs the “printf(“You are my best friend”); ” if the answer is COD or Java it skips that and prints We are enemies

asdiofjasdf says:

Hm, having a struggle. I dont know the difference between arrays and variables. Makes it difficult to know when to put &.

Osi famosi says:

Im not from the Us and i see lots of comments like “Your videos help me a lot at school”. My question is: is coding a common subject in the Us?

agenten says:

Hi these videos are amazing but I wonder if you could zoom in your text quite a bit because it’s very hard to sit back and watch on my small 1080p monitor.

Ani Pathak says:

ying tang says:

I write this code. When I put 71, it says “Bad choice.”, but when I put 7.9, it says”You make the right choice”. Why?


int main()
int number;
printf(“What is your favorite number? n”);
scanf(” %d”, &number);

if(number==7 || number==1){
printf (“nYou make the right choice.n”);
printf(“Bad choice.n”);
return 0;

I know this is stupid and simple compared to your guys’ stuff but I’m proud of it:


int main()
char answer;
printf(“Do you have school tomorrow? y/n n”);
scanf(” %c”, &answer);

if( (answer==’y’) || (answer==’n’) ){
printf(“Didn’t ask you. Shut it. n”);
int scale;
printf(“On a scale of 1-10, how mad are you right now? n”);
scanf(” %d”, &scale);

if(scale > 5){
printf(“ur mad lel n”);
if(scale < 5){ printf(“Get mad then! n”); } printf(“Goodbye.”); return 0; }

Nathan Coates says:

your so awesome

Mike M says:

make sure to use single quotes instead of double quotes when checking a statement. Single quotes are used for chars and double for strings.

Zackbare says:

Zero dislikes!!

Engku Fizz says:

erm.. why did you use %c instead of %s for string? and why we use single quotation instead of double quotation for y and n? is it because of y and n are not a string? if it is not a string then what it is?

vljzlj says:

It is gonna be displayed as “good job” even if they type ” yes” instead of just “y” because it stars with a “y” or “n”. :)

Gobberfisch says:

What about xor? C must have something like this, am I right?

Mo's TV says:

Can any body help me here .
I actually try running this code, but I keep getting error with in the if state that I don’t understand, the program is about asking user for their login name and afterward make sure that they provide the required name, using the if statement. 


int main(){
           char name[10];      // jubril, darame
    printf(“Enter Login namen”);
    scanf(” %s”,  name);
    printf(“welcome %s”, name);
    if (name == “jubril”) {
        printf(“you welcome sire “);       
        printf(“sorry u are not autorized here”);
    }return 0;

guoitdreuy says:

Hey I know this is just a simple example to show the OR test but I ran the program and entered yn and the program returned ‘good job you didn’t mess anything up’ How would you structure it so that it can ONLY be y or and not both? Cheers
