my code is not identifying type string. I am using c to program

CodePudding user response：

Parameter types are only put in function declarations, not function calls.

int letters = count_letters(string text);

should be

int letters = count_letters(text);

CodePudding user response：

C does not have a string type.

Although in C you can use the types char * and char[] to store and manipulate array of characters and treat them like strings.

define a string like this:

char *x = "hello"; // cannot be edited treat as read only (in most cases)

char x[5] = "hello";

char[5] = {'h','e','l','l','o','\0'}; // character at end signifies end of string
