a code to change string to uppercase using integer values within the code.

There are built in library and MFC functions to perform this. Please explain what you mean by "change string to uppercase using integer values"?

One of these days I'm going to think of a really clever signature.

Hint: There's an offset of 32 between lower and upper cased letters. For example, the ascii value (int) of lower case 'c' is 99, and the same of upper case 'C' is 67.

The integer difference between a lowercase char and a uppercase char when subtracted is 32. simply subtract the lowercase by 32 to get a uppercase char.

#include #include int main(void)
{
char strchr[32] = "the quick fox";
int strlength=strlen(strchr);

    printf("Before\\n" );
printf("%s\\n\\n", strchr);

for (int i=0; i\= 97) && (strchr\[i\] <= 122)) 
	{
		strchr\[i\] = strchr\[i\] -32;
		
	}
}
    printf("After\\n" );	 
printf("%s\\n\\n", strchr);

return(0);

}

Using hexadecimal rather than decimal integer values makes the code much more readable.

I would consider a different variable name as strchr is the name of a CRT function.

What about:

if (islower(strchr[i]))
strchr[i] = toupper(strchr[i]);

You're right about strchr() . and islower(). http://www.cplusplus.com/reference/clibrary/cstring/strchr/[^]
