strupr(), strlwr() and strrev() function in C | String Built-in Functions in C Programming [Part-1]
In this tutorial, I have demonstrated in Bangla the use of some string built-in functions like strupr(). strlwr() and strrev() string functions in C programming language with proper coding examples.
strupr(string) converts all the characters of the string to uppercase characters.
strlwr(string) converts all the characters of the string to lowercase characters.
