Hi Guys,
Look at the following code; Why doesnt it indicate whether its passed by val or pass by ref (by using the '&' operator?)? Or by default C is passed by ref?
Are there some default rules somehow?
Please advise
Code:/********************************************************************* * * Purpose: Reverse characters in a string. * Author: K&R * Date: * *********************************************************************/ void reverse(char s[]); main() { char text[80]="martin"; printf("string is %s\n", text); reverse(text); printf("string is %s\n", text); } void reverse(char s[]) { int c, i, j; for (i=0, j=strlen(s)-1; i < j;i++, j--) { c = s[i]; s[i] = s [j]; s[j] = c; } }
