18 C:\Dev-Cpp\project333 misc\cvc3roll.cpp expected primary-expression before ']' token

Code:

---

/* cvc3.h */

// roll string

#ifndef CVC3ROLL_H
#define CVC3ROLL_H

void rollup( char b[]) {
    for(int a; a < sizeof b ; a++ ) {
...
// roll func()
            }
            // std::cout << b << endl ;
            }
               
       
#endif


/* cvc3.cpp */

#include "cvc3rolle.h"
#include <iostream>

using namespace std;

int main(){
   
  char q[]  = "ababdddd test text of string for roll " ;
 
  for(int a = 0 ; a < 2 ; a++ ) {
          rollup(q[]);
          cout << q << endl;
          }

}

have tried "rollup(q)" rollup(&q) and changed .h to *q have tried

i know #define CVC3ROLL_H is diff from #include "cvc3rolle.h" .h mod several times seems not issue.

thinking cpp say

Code:

---

//: C03:Return.cpp
// Use of "return"
#include <iostream>
using namespace std;

char cfunc(int i) {
 ...
}

int main() {
  cout << "type an integer: ";
  int val;
  cin >> val;
  cout << cfunc(val) << endl;
} ///:~

almost same prog. mine use char while tcpp use int. and i use .h

tia any ideas ?

I'd say change:

Code:

---

void rollup( char b[]) {

---

to:

Code:

---

void rollup( char* b ) {

---

or even better:

Code:

---

void rollup( std::string& b ) {

---

i tried it that way. void rollup(char *q) already. got error can not convert chr* to char**.
took suggestion did it again with same error then i removed [] in the for loop. it compiled.

ok tested it worked. i messed up the for loop function call.
