Chapter 8: C Pointers and Arrays
void func1()func2 it is equal ‘n’, but this change has no effect on
in both functions is pure coincidence. We could}ut Let’s define:e it{
char olay = ‘m’;
...
func2(olay);
...
}
void func2(char olay)
{
...
olay++;
...
}
After olay is incremented in
olay in func1. The name ‘olay’
have func2:
void func2(char yalo)
{
...
yalo++;
...
and accomplished the same task.
B
void func2(char *)Then us
void func1()
{
char olay = ‘m’;
...
func2(&olay); // give func2 the address of the variable olay
...
}
