C++ length of a string

Question

Is there a way I can get the length of c++ string? (Purpose is so I can then copy the characters to another array)

Answer 1

if you are using C++, not C, you should be able to use std::string which has method length().

Answer 2

Perhaps this can help you.

Answer 3

// Use this function:
int lengthOf(string str) {
int len = 0;
while(str[len]) { // Gets the character at len index. If it is there, then it will return a
// character, which is true in boolean, but no character
// (aka end of string) will result in undefined, which is false.
len++;
}
return len;
}

Answer 4

or if you're using char array
char s[]="hello";
cout<<sizeof(s)/sizeof(s[0]); //6, because it end with \0

Answer 5

you can use strlen() to find string length...but to copy the string you don't need to use strlen(),,,you can use strcpy() to copy the string

Answer 6

For null terminated strings that originate in other functions you have strlen()
