Convert String to char

[9966]

Hi, currently I'm having a problem on converting a string type array into a char type. An example is as follows:

string fruits[20];
vector <char> temp;

The fruits array HAS to be a string type and temp vector HAS to be a char type. This can't be changed. So I've a problem on storing the element of fruits array into temp vector as follows:

temp.push_back(fruits[0]); <-----I know this is wrong.

So can I know how to convert string array into char type? Thank you

Are you sure about this??

A fruits element might be PEACH. All you can out in the vector is one letter, liked the P or A or the H.

However, if fruits[0] is a string then fruits[0][0] is the first character in the string.

hmm... yes actually that's what I want. Because initially I've stored all the fruit's name into a string array and it's used by other function. And somewhere down the whole code, I need to compare character by character of the fruit's name. For example:

1. P A P A Y A
2. P E A C H

I need to compare "P" with "P", since it's the same, then I've to proceed on the second alphabet which is "A" and "E" and so on...

And I don't understand why you said fruits[0][0] will be equal to "P". Could you please explain it further? Sorry I'm just a new learner..

You can imagine an array of string as an array of arrays, or a 2 dimensional array, if for example we have:

string fruits[3];
fruits[0] = "peach";
fruits[1] = "grape";
fruits[2] = "kiwi";
 

if you take fruits at position [0][0] you have char 'p', at position [0][1] you have the char 'e', at position fruits[2][2] you have char 'w'.
by looping through the fruits 2d array you can access all the chars.
this:

printf("%c", fruits[1][2]);
 

will print the char 'a'.

I see.. okay I'll try to implement it onto my code. Thanks a lot

1. P A P A Y A
2. P E A C H

It looks like you only need a vector<string>.

vector<string> fruits;
 

Can you not compare your names by:

if (fruits[1] == fruits[2])  // or fruits[1] < fruits[2])  etc...
{
//etc..
