ok thank you for help

i changed the code to avid overrun and you said better solution and more easy


[CODE]#include<stdio.h>

int main(){
int const MAX_LEN =100;
char arr[MAX_LEN];
int i;
int judge=0;

i changed the code


#include<stdio.h>

int main(){

char arr[100],OH[]={'O','o','H','h'};
int i,x=0;
printf("please input ");

that's right this is an array i edited the code



#include<stdio.h>



int main(){

yes i edited the code after i post it ,you posted too fast

hello,
this code give me the same output not OH


#include<stdio.h>

int main(){

char arr[100];
int i;

i'm going to do that practice and practice
i need more problems that let me learn

Working

#include<stdio.h>
#include<string.h>
int main()
{

i changed it then i changed it to 'A','Z'
thank you :)

:wink:
that's right no update happen in the main function it just change the value then nothing
The correct code

#include<stdio.h>
#include<string.h>
#include<stdbool.h>
char...

mr std10093
i red the topic about why not using BUFSIZ it's size changeable from compiler to other
so where can i use it socket programming or what ?
i mean best situation to use BUFSIZ an nothing...

mr.Adak
i will let user input in char array and i will check every char if it upper then change to lower if it lower change to upper and the ascii symbol normal
that's my logic can you write to me...

Thanks i forgot that c++ has toupper tolower function so i changed all name
i removed the second check in to_lower to_upper
and <= >=;

could you tell me what IDE or compiler you use?
i still...

i need program that i input string like this
TOSst!@
and output
tosST!@

the proplem in source that if write anything it just output it the same

i used fgets and made new var for strlen()
but the same proplem :frown:


#include<stdio.h>
#include<string.h>
#include<stdbool.h>
char toupper(char);
char tolower(char);
bool islower(char);

Hello
please
1-what is the proplem with this code
2-how can i use fgets in this code
3- can i use BUFSIZ
which will be more faster BUFSIZ or strlen()

thank you laserlight

okay but what must i do

:D thank you KansaiRobot



#include<stdio.h>
