C nested loops ➰

[@BroCodez]

#include
int main()
{
//nested loop = a loop inside of another loop
int rows;
int columns;
char symbol;
printf("
Enter # of rows: ");
scanf("%d", &rows);
printf("Enter # of columns: ");
scanf("%d", &columns);
scanf("%c"); //clears
from buffer
printf("Enter a symbol to use: ");
scanf("%c", &symbol);
for(int i = 1; i

i tried to run this but any number i input it always show 10 columns, why is that?

[@jrogeet]

nvm i fixed it, it works on devc++ compiler but in online compiler and vscode it didn't
so i just add &symbol at the end scanf("%c", &symbol); like this
instead of just scanf("%c");

Thank you very much, I was looking for something to explain the nested loop and how they interact which you explained in 3:14, "in order for one iteration of the inner loop to run, the inner loop basically has to end, to stop"

[@axiking6894]

if the scanf("%c"); don't work for some peoples, replace it by getchar(); at the same place he put the scanf("%c");

[@baradelv_]

thank you so much man

[@hamidabduljaabbar8419]

thanks

[@melsa8594]

Hello, it still doesnt work. What should I do?

[@axiking6894]

@@melsa8594 use scanf(%*c);

[@masterschlib]

you could also scan past the
character from scanf by putting a space before “%c”
like “ %c”
correct me if i’m wrong tho lol

[@nourguilal]

thnx G IT WORKS

[@ahmetyusufata]

at here right?: printf("Enter a symbol to use: ");
scanf(" %c", &symbol);

[@masterschlib]

@@ahmetyusufatayeah i think that’s right

[@jezrielmaydelossantosilawa6647]

my problem is I need to do a 5 10 15 20 up to 500 but it should be at 11 rows. how do I do that.

[@prosaufi3692]

First loop i is 11 times . Then 2nd loop just incremeent j += 5

[@Leshotgun]

vsc gets hung up on the fact that the additional scanf statment(the one added to clear the
) and it wont compute correctly

[@oscare123]

You could also write getchar(); to consume the /n
or you could add a space before %c like this scanf(" %c", &symbol); to tell it to ignore whitespace characters such as /n.

[@dillikalaunda4632]

hey! i love your channel! i tried to replicate this code and for some reason, it prints the character twice the number i put in columns, i fixed it by making the initial value of j = 6, but i dont think thats supposed to happen, cause it doesnt make any sense. please help?

[@OnkabetseMogomotsi-k1d]

My end results prints to infinite it never stops unless I kill the terminal and I did exactly like you did. What could I have done wrong?

[@frankezic4245]

thanks, Bro (Code)

[@giahuybui8323]

why my output is 10 columns even though I type another number when enter the columns
?

[@zuki2018]

Are you on a Mac? I have the same issue, using getchar(); instead of scanf("%c"); solves the problem, as suggested in comments below.

[@dkp8230]

Hey thanks man , that worked

[@PSIwolf39]

Here's a nested loop I made:
#include
#include
#include
#include
#include
int main(){
for(int i = 0; i

[@ZuKosElorian]

what is this abomination

[@Vegeta6777]

It recognises the enter rows, columns, and symbol but after that nothing prints ??

[@boweryst11]

tried anything but it just keeps saying more% conversions than data arguments

[@hamidabduljaabbar8419]

same here

[@crunchypatatas3939]

yoww is this C sharp? (C#)

[@elsayedelsaghir8723]

thank you bro

[@cholobikomochi5952]

Create a Program applying NESTED LOOP that will display the output 123 345 567. please help me i can not do it

[@houbini6097]

If you still need it. This should work.
#include
int main(void)
{
int j = 2;
int count;

for(int i=1; i

code... where?

[@ryanalnaser914]

whatever anything before or after or anything or I do or did or anything or anytime

[@amirrezabehzadi8520]

use this if scanf for clearing buffer not working,
while (getchar() != '
') { }

thank uuuuuuuu
