Capitalizing all characters of a string

Mar 14th, 2008

All I need to know is how to capitalize all of the characters of a string. What kinds of functions would I use?

you need a loop and the macro toupper(). For example of how to convert a single character to upper case please read the related thread that appeared immediately next to the one you created.

Don't PM me with questions -- you might get a nasty PM in response. If you have a question then post it in one of the forums.

you can make it a function:

 Help with Code Tags 
 c Syntax (Toggle Plain Text) 
void strToUppercase(char * myString)
{
   while(*myString)
      *myString = toupper(*myString++)
}
void strToUppercase(char * myString)
{
   while(*myString)
      *myString = toupper(*myString++)
}

or perhaps a more "easy to understand" bit of inline code:

 Help with Code Tags 
 c Syntax (Toggle Plain Text) 
char myString[128];
 
strcpy(myString,"the quick brown fox jumped over the lazy dogs");
 
for(a = 0; a<strlen(myString); a++)
{
   if (myString[a] >= 'a' && myString[a] <= 'z')
      myString[a] -= 0x20;
}
char myString[128];

strcpy(myString,"the quick brown fox jumped over the lazy dogs");

for(a = 0; a<strlen(myString); a++)
{
   if (myString[a] >= 'a' && myString[a] <= 'z')
      myString[a] -= 0x20;
}
