Any functions into which you pass string literals "I am a string literal"
should use char const *
as the type instead of char*
.
If you’re going to fix something, fix it right.
Explanation:
You can not use string literals to initialise strings that will be modified, because they are of type const char*
. Casting away the constness to later modify them is undefined behaviour, so you have to copy your const char*
strings char
by char
into dynamically allocated char*
strings in order to modify them.
Example:
#include <iostream>
void print(char* ch);
void print(const char* ch) {
std::cout<<ch;
}
int main() {
print("Hello");
return 0;
}
