C - Convert an uppercase letter to lowercase

Question

A really simple program  I just want to turn an  A  into an  a   but output is giving me  A      include  lt stdio h gt   int main void        putchar lower  A          lower a   int a         if   a  gt   65   amp  amp   a  gt   90           a   a   32       return a

You messed up the second part of your if condition  That should be a  lt   90   Also  FYI  there is a C library function tolower that does this already    include  lt ctype h gt   include  lt stdio h gt   int main         putchar tolower  A

I believe you want  lt   90  lower a   int a         if   a  gt   65   amp  amp   a  lt   90           a   a   32       return a        Although tolower would probably just save you the hassle unless you wanted to do this yourself  http   www cplusplus com reference cctype tolower

If condition is wrong  Also return type for lower is needed    include  lt stdio h gt   int lower int a          if   a  gt   65   amp  amp   a  lt   90           a   a   32       return a       int  tmain int argc   TCHAR  argv           putchar lower  A          return 0

Use This code   include lt stdio h gt   include lt conio h gt   include lt stdlib h gt  void main    char a 10   clrscr    gets a   int i length 0  for i 0 a i     0  i    length  1  for i 0 i lt length i     a i  a i  32    printf   s   amp a   getch

In ASCII the upper and lower case alphabet is 0x20  in ASCII 0x20 is space      apart from each other  so this is another way to do it   int lower int a         return a

include  lt stdio h gt   include  lt string h gt   int main         char string      Strlwr in C        printf   s n  strlwr string         return  0      use strlwr for lowering the case

One way to make sure it is correct is by using character instead of ascii code   if   a  gt   65   amp  amp   a  lt   90     what you want is to lower a case  it s better  to use something like if  a  gt    A   amp  amp  a  lt    Z     You don t have to remind all ascii code

include lt stdio h gt   void main      char a    clrscr     printf  enter a character      scanf   c   amp a     if a gt  65 amp  amp a lt  90     printf   c  a 32    else    printf  type a capital letter      getch

You can convert a character from lower case to upper case and vice-versa using bit manipulation as shown below    include lt stdio h gt  int main      char c    printf  Enter a character in uppercase n      scanf   c   amp c     c          perform or operation on c and       printf  The lower case of  c is  n  c     c amp          perform  and  operation with     to get upper case letter     printf  Back to upper case  c n  c        return 0

In ASCII the upper and lower case alphabet are 0x20 apart from each other  so this is another way to do it    int lower int a         if   a  gt   0x41   amp  amp   a  lt   0x5A           a    0x20       return a
