Thread: Lower to Upper

where do i insert the LowUpp(); function into my main(); to get it to make the lowercase letters into uppercase?

Code:

#include <stdio.h> 

int LowUpp(int ch)
{
	if ( 'a' <= ch && ch <= 'z' )
	{
		return (ch + 'A' - 'a');
	}
	else
	{
		return ch;
	}
}

int main() 
{
	int LowUpp(int ch);
	char word[50]; 
	char userstring[1024]; 
	int wordcount = 0; 
	int charcount = 0;
	int i = 0; 
	int j = 0; 

	printf("Enter your input: "); 

	if(fgets(userstring, 1024, stdin) == NULL) 
		return 0;

	while(userstring[i] != '\0') 
	{
		if((userstring[i] != ' ') && (userstring[i] != '\n') && (userstring[i] != '\t'))
		{
			charcount++;

			word[j++] = userstring[i]; 
		}

		else
		{
			word[j] = '\0';

			printf("%s \n", word); 
	
			wordcount++;
	
			j = 0;
		}

		i++; 
	} 

	printf("There were %d words and %d characters.\n", wordcount, charcount); 

	return 1;
}
