printf takes a format first and then it takes the values, example coming:

[wet aurora]

the %c %d thing?

[elder mist]

int a = 1;
int b = 2;

printf("%d + %d = %d", a, b, a + b);

[wet aurora]

ohh

so we cant just print variables directly

[elder mist]

indeed

[wet aurora]

int a =30;
int b = a+5;
int c =b+1, e;
printf ("%d", a , "%d" , b , "%d", c , "%d", e)

is this the correct way?

[elder mist]

no, first comes the format as the first argument, then come the values

[wet aurora]

hmm

[elder mist]

printf(formatString, ...values)

also, what are you trying to achieve with int c =b+1, e;

[wet aurora]

int a =30;
int b = a+5;
int c =b+1, e;
printf ("%d , %d , %d, %d", a , b, c, e)

[elder mist]

yes printf is correct there

don't forget your ; tho

[wet aurora]

i wass looking at a tutorial and it was showing how one can declare e too as a variable but not assiging any value to it

[elder mist]

ah, that's indeed what that does

[wet aurora]

yes sir!

[wet aurora]

tysm for the help!

[elder mist]

nw

Thank you and let us know if you have any more questions!

This thread is now set to auto-hide after an hour of inactivity

[wet aurora]

#include<stdio.h>

int main(){
    int a=30;
    int b=a+5;
    int c= b+1, e;
    printf("%d , %d , %d, %d", a , b, c, e);
}```
it is still showing the same problem tho

argument of type "int" is incompatible with parameter of type "const char *"

[elder mist]

I mean it compiles for me

are you actually building?

[wet aurora]

no im just running this

[elder mist]

your intellisense might not yet have caught up

[wet aurora]

im a beginner

[elder mist]

how are you running it

[wet aurora]

gcc

[elder mist]

show your process

[elder mist]

are you running it or is it just showing that before running

[wet aurora]

this is before running

[wet aurora]

and this comes after running

[elder mist]

your instructions.c file doesn't exist

gcc must be run in the same folder where the c file is

or you must specify the full path to the folder where it is + the c file

[wet aurora]

hmm i think you are right

im typing the name wrong

its instruction.c

💀

[wet aurora]

one more question

the e variable dont have a value assigned

why is e coming as 4200816?

[elder mist]

well yesn't, you didn't initialize it
it did make space on your memory for it.
that means that whatever was there before you made space for it in memory will be shown

i.e. useless garbage

hence why you'd always want to set a value before using a variable

or you'll get something random

[wet aurora]

wait

so like the space it was assigned to it

previously haad 4200816 stored in it

and thats why it got printed//

?

[elder mist]

ye

something like that

[wet aurora]

hmm okay!

thanks once again for the help!

[elder mist]

np

[tropic yoke]

It’s undefined behavior. Maybe that was a value that was stored there previously, or maybe not. It could be a value filled by the OS or literally anything else

[wet aurora]

Alright thanks!
