So direct and to the point, yet very instructional. You're the best bro.

strlwr(string) and strupr(string) don't exist in standard c library string.h. you have to have a little fun and create it yourself, by using a loop that calculates the correspondent lower/uppercase char in the ASCII table and replacing it, or usinc ctype.h and tolower()/toupper() functions to convert cases. the same for strset(), strnset(), strrev(), strcmpi() and strnicmp() not defining the size of the strings results in stack overflow/stack smashing and unexpected behaviour. Examples for string to lowercase/uppercase (this doesn't accept string literals as arguments): #include char* stringToUpper(char * string){ int i = 0; while (string[i] != '\0'){ string[i] = (char)toupper(string[i]); i++; } return string; } char* stringToLower(char * string){ int i = 0; while (string[i] != '\0'){ string[i] = (char)tolower(string[i]); i++; } return string; }

[@QuimChaos]

better, much better: #include #include void stringToUpper(char * string){ while (*string != '\0'){ *string = (char)toupper(*string); string++; } } void stringToLower(char * string){ while (*string != '\0'){ *string = (char)tolower(*string); string++; } } int main() { char string1[50] = "Hello"; stringToUpper(string1); printf("To upper %s ", string1); stringToLower(string1); printf("To lower %s ", string1); return 0; }

I cannot find those two functions in IBM documentary for C standard libraries, although it works in Visual Studio Code. Maybe they added those function recently?

[@brisauce6944]

Thank you for clarifying this! It's confusing to a new programmer like me when I see things like "implicit declaration of is not valid in c99", despite it being mentioned in a tutorial video. You're a sanity saver man!

[@Birendra-Chess]

Thank You bro, I Wasted one hour on this.

[@kennya51]

The in MacOS/Linux different of that of the Windows . strlwr(), strupr() are "non-standard", so they only exist in the Windows one, which BroCode is using.

[@xetycm.8923]

I was to so some of the functions (like strlwr, strcmpi, and etc) but for some reason they didn't exist in the string.h library (it kept saying the function doesn't exist). some people suggest that I make these functions myself using other libraries; but is there a way to fix the issue i'm having?

How can strcat() make string1 bigger without malloc? And I thought that a string created using [] is constant.

[@kurisey8020]

What does case sensitivity mean?

[@akeem3127]

Upper vs upper, if the first was a variable and you try to print with a second it would give and error

[@delright6829]

im little bit confused everything here works besides strset,strnset and strrev vs isnt recognizing them. i believe theyre not included in string.h and stdio.h is there a fix to it ? im writing my exam next week and were only allowed to use libraries we got shown example: bool etc aint allowed.

Sir, strupr and strlwr both these functions aren't working even after including string header file. How to fix it

[@trungdu9354]

Looked up source of didn't see them function in there so to fix had to manually write a internal code inside code, or could make my own newfunction.c file and import it there since going use it often (Put these 2 codes above your int main() not inside it) //Beginner Version strlwr() char * strlwr(char * s){ char *t = s; if (!s){ return 0; } int i = 0; while ( *t != '\0' ){ if (*t >= 'A' && *t = 'a' && *t

Thank you ❤️

[@mohammedisarezwani]

how can we remember all these functions ?

[@Mr.noname_]

by taking notes my dear haha

[@zraie2455]

You don't need to remember all these functions! You can pretty much write code using your knowledge so far that accomplishes what these functions do. Knowing these functions just makes it easier for you to write code as you won't have to write new functions in your code with a specific purpose if you remember that there's a library which already does that. I.e. you won't have to create an pow(x, y) function in your program if you remember that math.h has a library with a similar function.

@@_____Shadow_____ yes, i did. still, it didn't work.

it would help if you share which error did you get when you tried to run em

[@collin7776]

@@tituskace5566 So the strlwr and strupr along with some other functions listed in this video are part of the Microsoft implementation of C. Mac/linux/unix have to use different functions to alter strings. You can either use the ctype.h or code the functions yourself.
