Function input may char or char[] ..?

[GSalah]

Dear all , I have a function , and I need to use this function to deal with char and char[] , is this the idea of template ? and if so , how can I distinguish if the input is char or char[] ?

thanks

void foo(int a) {}
void foo(double a) {} //correct, the two foo()s are different in argument type
void foo(char a) {} //still correct
void foo(char *a) {} //acceptable
void foo(my_class a) {} //any type will do
int foo(my_class a) {} //error, return types don't count

Just so you know, templates are a rather different kind of animal.

It sounds like you're describing a need for function overloading.

#include <stdio.h>

void process (char c) {
  printf ("Handling a char: %c\n", c);
}

void process (char c[]) {
  printf ("Handling an array: %s\n", c);
}

int main (void) {
  char letter='A';
  char name[] = "James";

  process(letter);
  process(name);

  return 0;
}
